Having - two buttons labeled "OK" in different windows or different tree locations is fine. - We used "..." above to signify whatever was already pushed to the ID stack previously: - - Begin("MyWindow"); - Button("OK"); // Label = "OK", ID = hash of ("MyWindow", "OK") - End(); - Begin("MyOtherWindow"); - Button("OK"); // Label = "OK", ID = hash of ("MyOtherWindow", "OK") - End(); - - - If you have a same ID twice in the same location, you'll have a conflict: - - Button("OK"); - Button("OK"); // ID collision! Interacting with either button will trigger the first one. - - Fear not! this is easy to solve and there are many ways to solve it! - - - Solving ID conflict in a simple/local context: - When passing a label you can optionally specify extra ID information within string itself. - Use "##" to pass a complement to the ID that won't be visible to the end-user. - This helps solving the simple collision cases when you know e.g. at compilation time which items - are going to be created: - - Begin("MyWindow"); - Button("Play"); // Label = "Play", ID = hash of ("MyWindow", "Play") - Button("Play##foo1"); // Label = "Play", ID = hash of ("MyWindow", "Play##foo1") // Different from above - Button("Play##foo2"); // Label = "Play", ID = hash of ("MyWindow", "Play##foo2") // Different from above - End(); - - - If you want to completely hide the label, but still need an ID: - - Checkbox("##On", &b); // Label = "", ID = hash of (..., "##On") // No visible label, just a checkbox! - - - Occasionally/rarely you might want change a label while preserving a constant ID. This allows - you to animate labels. For example you may want to include varying information in a window title bar, - but windows are uniquely identified by their ID. Use "###" to pass a label that isn't part of ID: - - Button("Hello###ID"); // Label = "Hello", ID = hash of (..., "###ID") - Button("World###ID"); // Label = "World", ID = hash of (..., "###ID") // Same as above, even though the label looks different - - sprintf(buf, "My game (%f FPS)###MyGame", fps); - Begin(buf); // Variable title, ID = hash of "MyGame" - - - Solving ID conflict in a more general manner: - Use PushID() / PopID() to create scopes and manipulate the ID stack, as to avoid ID conflicts - within the same window. This is the most convenient way of distinguishing ID when iterating and - creating many UI elements programmatically. - You can push a pointer, a string or an integer value into the ID stack. - Remember that ID are formed from the concatenation of _everything_ pushed into the ID stack. - At each level of the stack we store the seed used for items at this level of the ID stack. - - Begin("Window"); - for (int i = 0; i < 100; i++) - { - PushID(i); // Push i to the id tack - Button("Click"); // Label = "Click", ID = hash of ("Window", i, "Click") - PopID(); - } - for (int i = 0; i < 100; i++) - { - MyObject* obj = Objects[i]; - PushID(obj); - Button("Click"); // Label = "Click", ID = hash of ("Window", obj pointer, "Click") - PopID(); - } - for (int i = 0; i < 100; i++) - { - MyObject* obj = Objects[i]; - PushID(obj->Name); - Button("Click"); // Label = "Click", ID = hash of ("Window", obj->Name, "Click") - PopID(); - } - End(); - - - You can stack multiple prefixes into the ID stack: - - Button("Click"); // Label = "Click", ID = hash of (..., "Click") - PushID("node"); - Button("Click"); // Label = "Click", ID = hash of (..., "node", "Click") - PushID(my_ptr); - Button("Click"); // Label = "Click", ID = hash of (..., "node", my_ptr, "Click") - PopID(); - PopID(); - - - Tree nodes implicitly creates a scope for you by calling PushID(). - - Button("Click"); // Label = "Click", ID = hash of (..., "Click") - if (TreeNode("node")) // <-- this function call will do a PushID() for you (unless instructed not to, with a special flag) - { - Button("Click"); // Label = "Click", ID = hash of (..., "node", "Click") - TreePop(); - } - - - When working with trees, ID are used to preserve the open/close state of each tree node. - Depending on your use cases you may want to use strings, indices or pointers as ID. - e.g. when following a single pointer that may change over time, using a static string as ID - will preserve your node open/closed state when the targeted object change. - e.g. when displaying a list of objects, using indices or pointers as ID will preserve the - node open/closed state differently.

It provides a simple, platform-independent API for +creating windows, contexts and surfaces, reading input, handling events, etc. + +GLFW natively supports Windows, macOS and Linux and other Unix-like systems. +Experimental implementations for the Wayland protocol and the Mir display server +are available but not yet officially supported. + +GLFW is licensed under the [zlib/libpng +license](http://www.glfw.org/license.html). + +The latest stable release is version 3.2.1. + +See the [downloads](http://www.glfw.org/download.html) page for details and +files, or fetch the `latest` branch, which always points to the latest stable +release. Each release starting with 3.0 also has a corresponding [annotated +tag](https://github.com/glfw/glfw/releases) with source and binary archives. +The [version history](http://www.glfw.org/changelog.html) lists all user-visible +changes for every release. + +This is a development branch for version 3.3, which is _not yet described_. +Pre-release documentation is available [here](http://www.glfw.org/docs/3.3/). + +The `master` branch is the stable integration branch and _should_ always compile +and run on all supported platforms, although details of newly added features may +change until they have been included in a release. New features and many bug +fixes live in [other branches](https://github.com/glfw/glfw/branches/all) until +they are stable enough to merge. + +If you are new to GLFW, you may find the +[tutorial](http://www.glfw.org/docs/latest/quick.html) for GLFW 3 useful. If +you have used GLFW 2 in the past, there is a [transition +guide](http://www.glfw.org/docs/latest/moving.html) for moving to the GLFW +3 API. + + +## Compiling GLFW + +GLFW itself requires only the headers and libraries for your window system. It +does not need the headers for any context creation API (WGL, GLX, EGL, NSGL, +OSMesa) or rendering API (OpenGL, OpenGL ES, Vulkan) to enable support for them. + +GLFW supports compilation on Windows with Visual C++ 2010 and later, MinGW and +MinGW-w64, on macOS with Clang and on Linux and other Unix-like systems with GCC +and Clang. It will likely compile in other environments as well, but this is +not regularly tested. + +There are [pre-compiled Windows binaries](http://www.glfw.org/download.html) +available for all supported compilers. + +See the [compilation guide](http://www.glfw.org/docs/latest/compile.html) for +more information about how to compile GLFW yourself. + + +## Using GLFW + +See the [documentation](http://www.glfw.org/docs/latest/) for tutorials, guides +and the API reference. + + +## Contributing to GLFW + +See the [contribution +guide](https://github.com/glfw/glfw/blob/master/docs/CONTRIBUTING.md) for +more information. + + +## System requirements + +GLFW supports Windows XP and later and macOS 10.7 and later. Linux and other +Unix-like systems running the X Window System are supported even without +a desktop environment or modern extensions, although some features require +a running window or clipboard manager. The OSMesa backend requires Mesa 6.3. + +See the [compatibility guide](http://www.glfw.org/docs/latest/compat.html) +in the documentation for more information. + + +## Dependencies + +GLFW itself depends only on the headers and libraries for your window system. + +The (experimental) Wayland backend also depends on the `extra-cmake-modules` +package, which is used to generated Wayland protocol headers. + +The examples and test programs depend on a number of tiny libraries. These are +located in the `deps/` directory. + + - [getopt\_port](https://github.com/kimgr/getopt_port/) for examples + with command-line options + - [TinyCThread](https://github.com/tinycthread/tinycthread) for threaded + examples + - An OpenGL 3.2 core loader generated by + [glad](https://github.com/Dav1dde/glad) for examples using modern OpenGL + - [linmath.h](https://github.com/datenwolf/linmath.h) for linear algebra in + examples + - [Nuklear](https://github.com/vurtun/nuklear) for test and example UI + - [stb\_image\_write](https://github.com/nothings/stb) for writing images to disk + - [Vulkan headers](https://www.khronos.org/registry/vulkan/) for Vulkan tests + +The Vulkan example additionally requires the LunarG Vulkan SDK to be installed, +or it will not be included in the build. On macOS you need to provide the path +to the SDK manually as it has no standard installation location. + +The documentation is generated with [Doxygen](http://doxygen.org/) if CMake can +find that tool. + + +## Reporting bugs + +Bugs are reported to our [issue tracker](https://github.com/glfw/glfw/issues). +Please check the [contribution +guide](https://github.com/glfw/glfw/blob/master/docs/CONTRIBUTING.md) for +information on what to include when reporting a bug. + + +## Changelog + +- Added `glfwGetError` function for querying the

Important + * here is that if you define more widgets then columns defined inside the layout + * functions it will allocate the next row without you having to make another layouting + * call. + * + * Biggest limitation with using all these APIs outside the `nk_layout_space_xxx` API + * is that you have to define the row height for each. However the row height + * often depends on the height of the font. + * + * To fix that internally nuklear uses a minimum row height that is set to the + * height plus padding of currently active font and overwrites the row height + * value if zero. + * + * If you manually want to change the minimum row height then + * use nk_layout_set_min_row_height, and use nk_layout_reset_min_row_height to + * reset it back to be derived from font height. + * + * Also if you change the font in nuklear it will automatically change the minimum + * row height for you and. This means if you change the font but still want + * a minimum row height smaller than the font you have to repush your value. + * + * For actually more advanced UI I would even recommend using the `nk_layout_space_xxx` + * layouting method in combination with a cassowary constraint solver (there are + * some versions on github with permissive license model) to take over all control over widget + * layouting yourself. However for quick and dirty layouting using all the other layouting + * functions should be fine. + * + * Usage + * ------------------- + * 1.) nk_layout_row_dynamic + * The easiest layouting function is `nk_layout_row_dynamic`. It provides each + * widgets with same horizontal space inside the row and dynamically grows + * if the owning window grows in width. So the number of columns dictates + * the size of each widget dynamically by formula: + * + * widget_width = (window_width - padding - spacing) * (1/colum_count) + * + * Just like all other layouting APIs if you define more widget than columns this + * library will allocate a new row and keep all layouting parameters previously + * defined. + * + * if (nk_begin_xxx(...) { + * // first row with height: 30 composed of two widgets + * nk_layout_row_dynamic(&ctx, 30, 2); + * nk_widget(...); + * nk_widget(...); + * + * // second row with same parameter as defined above + * nk_widget(...); + * nk_widget(...); + * + * // third row uses 0 for height which will use auto layouting + * nk_layout_row_dynamic(&ctx, 0, 2); + * nk_widget(...); + * nk_widget(...); + * } + * nk_end(...); + * + * 2.) nk_layout_row_static + * Another easy layouting function is `nk_layout_row_static`. It provides each + * widget with same horizontal pixel width inside the row and does not grow + * if the owning window scales smaller or bigger. + * + * if (nk_begin_xxx(...) { + * // first row with height: 30 composed of two widgets with width: 80 + * nk_layout_row_static(&ctx, 30, 80, 2); + * nk_widget(...); + * nk_widget(...); + * + * // second row with same parameter as defined above + * nk_widget(...); + * nk_widget(...); + * + * // third row uses 0 for height which will use auto layouting + * nk_layout_row_static(&ctx, 0, 80, 2); + * nk_widget(...); + * nk_widget(...); + * } + * nk_end(...); + * + * 3.) nk_layout_row_xxx + * A little bit more advanced layouting API are functions `nk_layout_row_begin`, + * `nk_layout_row_push` and `nk_layout_row_end`. They allow to directly + * specify each column pixel or window ratio in a row. It supports either + * directly setting per column pixel width or widget window ratio but not + * both. Furthermore it is a immediate mode API so each value is directly + * pushed before calling a widget. Therefore the layout is not automatically + * repeating like the last two layouting functions. + * + * if (nk_begin_xxx(...) { + * // first row with height: 25 composed of two widgets with width 60 and 40 + * nk_layout_row_begin(ctx, NK_STATIC, 25, 2); + * nk_layout_row_push(ctx, 60); + * nk_widget(...); + * nk_layout_row_push(ctx, 40); + * nk_widget(...); + * nk_layout_row_end(ctx); + * + * // second row with height: 25 composed of two widgets with window ratio 0.25 and 0.75 + * nk_layout_row_begin(ctx, NK_DYNAMIC, 25, 2); + * nk_layout_row_push(ctx, 0.25f); + * nk_widget(...); + * nk_layout_row_push(ctx, 0.75f); + * nk_widget(...); + * nk_layout_row_end(ctx); + * + * // third row with auto generated height: composed of two widgets with window ratio 0.25 and 0.75 + * nk_layout_row_begin(ctx, NK_DYNAMIC, 0, 2); + * nk_layout_row_push(ctx, 0.25f); + * nk_widget(...); + * nk_layout_row_push(ctx, 0.75f); + * nk_widget(...); + * nk_layout_row_end(ctx); + * } + * nk_end(...); + * + * 4.) nk_layout_row + * The array counterpart to API nk_layout_row_xxx is the single nk_layout_row + * functions. Instead of pushing either pixel or window ratio for every widget + * it allows to define it by array. The trade of for less control is that + * `nk_layout_row` is automatically repeating. Otherwise the behavior is the + * same. + * + * if (nk_begin_xxx(...) { + * // two rows with height: 30 composed of two widgets with width 60 and 40 + * const float size[] = {60,40}; + * nk_layout_row(ctx, NK_STATIC, 30, 2, ratio); + * nk_widget(...); + * nk_widget(...); + * nk_widget(...); + * nk_widget(...); + * + * // two rows with height: 30 composed of two widgets with window ratio 0.25 and 0.75 + * const float ratio[] = {0.25, 0.75}; + * nk_layout_row(ctx, NK_DYNAMIC, 30, 2, ratio); + * nk_widget(...); + * nk_widget(...); + * nk_widget(...); + * nk_widget(...); + * + * // two rows with auto generated height composed of two widgets with window ratio 0.25 and 0.75 + * const float ratio[] = {0.25, 0.75}; + * nk_layout_row(ctx, NK_DYNAMIC, 30, 2, ratio); + * nk_widget(...); + * nk_widget(...); + * nk_widget(...); + * nk_widget(...); + * } + * nk_end(...); + * + * 5.) nk_layout_row_template_xxx + * The most complex and second most flexible API is a simplified flexbox version without + * line wrapping and weights for dynamic widgets. It is an immediate mode API but + * unlike `nk_layout_row_xxx` it has auto repeat behavior and needs to be called + * before calling the templated widgets. + * The row template layout has three different per widget size specifier. The first + * one is the static widget size specifier with fixed widget pixel width. They do + * not grow if the row grows and will always stay the same. The second size + * specifier is nk_layout_row_template_push_variable which defines a + * minimum widget size but it also can grow if more space is available not taken + * by other widgets. Finally there are dynamic widgets which are completely flexible + * and unlike variable widgets can even shrink to zero if not enough space + * is provided. + * + * if (nk_begin_xxx(...) { + * // two rows with height: 30 composed of three widgets + * nk_layout_row_template_begin(ctx, 30); + * nk_layout_row_template_push_dynamic(ctx); + * nk_layout_row_template_push_variable(ctx, 80); + * nk_layout_row_template_push_static(ctx, 80); + * nk_layout_row_template_end(ctx); + * + * nk_widget(...); // dynamic widget can go to zero if not enough space + * nk_widget(...); // variable widget with min 80 pixel but can grow bigger if enough space + * nk_widget(...); // static widget with fixed 80 pixel width + * + * // second row same layout + * nk_widget(...); + * nk_widget(...); + * nk_widget(...); + * } + * nk_end(...); + * + * 6.) nk_layout_space_xxx + * Finally the most flexible API directly allows you to place widgets inside the + * window. The space layout API is an immediate mode API which does not support + * row auto repeat and directly sets position and size of a widget. Position + * and size hereby can be either specified as ratio of allocated space or + * allocated space local position and pixel size. Since this API is quite + * powerful there are a number of utility functions to get the available space + * and convert between local allocated space and screen space. + * + * if (nk_begin_xxx(...) { + * // static row with height: 500 (you can set column count to INT_MAX if you don't want to be bothered) + * nk_layout_space_begin(ctx, NK_STATIC, 500, INT_MAX); + * nk_layout_space_push(ctx, nk_rect(0,0,150,200)); + * nk_widget(...); + * nk_layout_space_push(ctx, nk_rect(200,200,100,200)); + * nk_widget(...); + * nk_layout_space_end(ctx); + * + * // dynamic row with height: 500 (you can set column count to INT_MAX if you don't want to be bothered) + * nk_layout_space_begin(ctx, NK_DYNAMIC, 500, INT_MAX); + * nk_layout_space_push(ctx, nk_rect(0.5,0.5,0.1,0.1)); + * nk_widget(...); + * nk_layout_space_push(ctx, nk_rect(0.7,0.6,0.1,0.1)); + * nk_widget(...); + * } + * nk_end(...); + * + * Reference + * ------------------- + * nk_layout_set_min_row_height - set the currently used minimum row height to a specified value + * nk_layout_reset_min_row_height - resets the currently used minimum row height to font height + * + * nk_layout_widget_bounds - calculates current width a static layout row can fit inside a window + * nk_layout_ratio_from_pixel - utility functions to calculate window ratio from pixel size + * + * nk_layout_row_dynamic - current layout is divided into n same sized growing columns + * nk_layout_row_static - current layout is divided into n same fixed sized columns + * nk_layout_row_begin - starts a new row with given height and number of columns + * nk_layout_row_push - pushes another column with given size or window ratio + * nk_layout_row_end - finished previously started row + * nk_layout_row - specifies row columns in array as either window ratio or size + * + * nk_layout_row_template_begin - begins the row template declaration + * nk_layout_row_template_push_dynamic - adds a dynamic column that dynamically grows and can go to zero if not enough space + * nk_layout_row_template_push_variable - adds a variable column that dynamically grows but does not shrink below specified pixel width + * nk_layout_row_template_push_static - adds a static column that does not grow and will always have the same size + * nk_layout_row_template_end - marks the end of the row template + * + * nk_layout_space_begin - begins a new layouting space that allows to specify each widgets position and size + * nk_layout_space_push - pushes position and size of the next widget in own coordinate space either as pixel or ratio + * nk_layout_space_end - marks the end of the layouting space + * + * nk_layout_space_bounds - callable after nk_layout_space_begin and returns total space allocated + * nk_layout_space_to_screen - converts vector from nk_layout_space coordinate space into screen space + * nk_layout_space_to_local - converts vector from screen space into nk_layout_space coordinates + * nk_layout_space_rect_to_screen - converts rectangle from nk_layout_space coordinate space into screen space + * nk_layout_space_rect_to_local - converts rectangle from screen space into nk_layout_space coordinates + */ +/* nk_layout_set_min_row_height - sets the currently used minimum row height. + * IMPORTANT: The passed height needs to include both your preferred row height + * as well as padding.

+/* =============================================================== + * + * FONT + * + * ===============================================================*/ +/* Font handling in this library was designed to be quite customizable and lets + you decide what you want to use and what you want to provide. There are three + different ways to use the font atlas. The first two will use your font + handling scheme and only requires essential data to run nuklear. The next + slightly more advanced features is font handling with vertex buffer output. + Finally the most complex API wise is using nuklear's font baking API. + + 1.) Using your own implementation without vertex buffer output + -------------------------------------------------------------- + So first up the easiest way to do font handling is by just providing a + `nk_user_font` struct which only requires the height in pixel of the used + font and a callback to calculate the width of a string. This way of handling + fonts is best fitted for using the normal draw shape command API where you + do all the text drawing yourself and the library does not require any kind + of deeper knowledge about which font handling mechanism you use. + IMPORTANT: the `nk_user_font` pointer provided to nuklear has to persist + over the complete life time! I know this sucks but it is currently the only + way to switch between fonts. + + float your_text_width_calculation(nk_handle handle, float height, const char *text, int len) + { + your_font_type *type = handle.ptr; + float text_width = ...; + return text_width; + } + + struct nk_user_font font; + font.userdata.ptr = &your_font_class_or_struct; + font.height = your_font_height; + font.width = your_text_width_calculation; + + struct nk_context ctx; + nk_init_default(&ctx, &font); + + 2.) Using your own implementation with vertex buffer output + -------------------------------------------------------------- + While the first approach works fine if you don't want to use the optional + vertex buffer output it is not enough if you do. To get font handling working + for these cases you have to provide two additional parameters inside the + `nk_user_font`. First a texture atlas handle used to draw text as subimages + of a bigger font atlas texture and a callback to query a character's glyph + information (offset, size, ...).

Nuklear font baker + ------------------------------------ + The final approach if you do not have a font handling functionality or don't + want to use it in this library is by using the optional font baker. + The font baker APIs can be used to create a font plus font atlas texture + and can be used with or without the vertex buffer output. + + It still uses the `nk_user_font` struct and the two different approaches + previously stated still work. The font baker is not located inside + `nk_context` like all other systems since it can be understood as more of + an extension to nuklear and does not really depend on any `nk_context` state. + + Font baker need to be initialized first by one of the nk_font_atlas_init_xxx + functions. If you don't care about memory just call the default version + `nk_font_atlas_init_default` which will allocate all memory from the standard library. + If you want to control memory allocation but you don't care if the allocated + memory is temporary and therefore can be freed directly after the baking process + is over or permanent you can call `nk_font_atlas_init`. + + After successfully initializing the font baker you can add Truetype(.ttf) fonts from + different sources like memory or from file by calling one of the `nk_font_atlas_add_xxx`. + functions. Adding font will permanently store each font, font config and ttf memory block(!) + inside the font atlas and allows to reuse the font atlas. If you don't want to reuse + the font baker by for example adding additional fonts you can call + `nk_font_atlas_cleanup` after the baking process is over (after calling nk_font_atlas_end). + + As soon as you added all fonts you wanted you can now start the baking process + for every selected glyph to image by calling `nk_font_atlas_bake`. + The baking process returns image memory, width and height which can be used to + either create your own image object or upload it to any graphics library. + No matter which case you finally have to call `nk_font_atlas_end` which + will free all temporary memory including the font atlas image so make sure + you created our texture beforehand. `nk_font_atlas_end` requires a handle + to your font texture or object and optionally fills a `struct nk_draw_null_texture` + which can be used for the optional vertex output. If you don't want it just + set the argument to `NULL`. + + At this point you are done and if you don't want to reuse the font atlas you + can call `nk_font_atlas_cleanup` to free all truetype blobs and configuration + memory. Finally if you don't use the font atlas and any of it's fonts anymore + you need to call `nk_font_atlas_clear` to free all memory still being used. + + struct nk_font_atlas atlas; + nk_font_atlas_init_default(&atlas); + nk_font_atlas_begin(&atlas); + nk_font *font = nk_font_atlas_add_from_file(&atlas, "Path/To/Your/TTF_Font.ttf", 13, 0); + nk_font *font2 = nk_font_atlas_add_from_file(&atlas, "Path/To/Your/TTF_Font2.ttf", 16, 0); + const void* img = nk_font_atlas_bake(&atlas, &img_width, &img_height, NK_FONT_ATLAS_RGBA32); + nk_font_atlas_end(&atlas, nk_handle_id(texture), 0); + + struct nk_context ctx; + nk_init_default(&ctx, &font->handle); + while (1) { + + } + nk_font_atlas_clear(&atlas); + + The font baker API is probably the most complex API inside this library and + I would suggest reading some of my examples `example/` to get a grip on how + to use the font atlas.

use at your own risk + + Before #including, + + #define STB_IMAGE_WRITE_IMPLEMENTATION + + in the file that you want to have the implementation. + + Will probably not work correctly with strict-aliasing optimizations. + +ABOUT: + + This header file is a library for writing images to C stdio. It could be + adapted to write to memory or a general streaming interface; let me know. + + The PNG output is not optimal; it is 20-50% larger than the file + written by a decent optimizing implementation. This library is designed + for source code compactness and simplicity, not optimal image file size + or run-time performance. + +BUILDING: + + You can #define STBIW_ASSERT(x) before the #include to avoid using assert.h. + You can #define STBIW_MALLOC(), STBIW_REALLOC(), and STBIW_FREE() to replace + malloc,realloc,free. + You can define STBIW_MEMMOVE() to replace memmove() + +USAGE: + + There are four functions, one for each image file format: + + int stbi_write_png(char const *filename, int w, int h, int comp, const void *data, int stride_in_bytes); + int stbi_write_bmp(char const *filename, int w, int h, int comp, const void *data); + int stbi_write_tga(char const *filename, int w, int h, int comp, const void *data); + int stbi_write_hdr(char const *filename, int w, int h, int comp, const float *data); + + There are also four equivalent functions that use an arbitrary write function. You are + expected to open/close your file-equivalent before and after calling these: + + int stbi_write_png_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data, int stride_in_bytes); + int stbi_write_bmp_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data); + int stbi_write_tga_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data); + int stbi_write_hdr_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const float *data); + + where the callback is: + void stbi_write_func(void *context, void *data, int size); + + You can define STBI_WRITE_NO_STDIO to disable the file variant of these + functions, so the library will not use stdio.h at all. However, this will + also disable HDR writing, because it requires stdio for formatted output. + + Each function returns 0 on failure and non-0 on success. + + The functions create an image file defined by the parameters. The image + is a rectangle of pixels stored from left-to-right, top-to-bottom. + Each pixel contains 'comp' channels of data stored interleaved with 8-bits + per channel, in the following order: 1=Y, 2=YA, 3=RGB, 4=RGBA. (Y is + monochrome color.) The rectangle is 'w' pixels wide and 'h' pixels tall. + The *data pointer points to the first byte of the top-left-most pixel. + For PNG, "stride_in_bytes" is the distance in bytes from the first byte of + a row of pixels to the first byte of the next row of pixels. + + PNG creates output files with the same number of components as the input. + The BMP format expands Y to RGB in the file format and does not + output alpha. + + PNG supports writing rectangles of data even when the bytes storing rows of + data are not consecutive in memory (e.g. sub-rectangles of a larger image), + by supplying the stride between the beginning of adjacent rows. The other + formats do not. (Thus you cannot write a native-format BMP through the BMP + writer, both because it is in BGR order and because it may have padding + at the end of the line.) + + HDR expects linear float data. Since the format is always 32-bit rgb(e) + data, alpha (if provided) is discarded, and for monochrome data it is + replicated across all three channels. + + TGA supports RLE or non-RLE compressed data. To use non-RLE-compressed + data, set the global variable 'stbi_write_tga_with_rle' to 0. + +CREDITS: + + PNG/BMP/TGA + Sean Barrett + HDR + Baldur Karlsson + TGA monochrome: + Jean-Sebastien Guay + misc enhancements: + Tim Kelsey + TGA RLE + Alan Hickman + initial file IO callback implementation + Emmanuel Julien + bugfixes: + github:Chribba + Guillaume Chereau + github:jry2 + github:romigrou + Sergio Gonzalez + Jonas Karlsson + Filip Wasil + Thatcher Ulrich + +LICENSE + +This software is dual-licensed to the public domain and under the following +license: you are granted a perpetual, irrevocable license to copy, modify, +publish, and distribute this file as you see fit. + +*/ + +#ifndef INCLUDE_STB_IMAGE_WRITE_H +#define INCLUDE_STB_IMAGE_WRITE_H + +#ifdef __cplusplus +extern "C" { +#endif + +#ifdef STB_IMAGE_WRITE_STATIC +#define STBIWDEF static +#else +#define STBIWDEF extern +extern int stbi_write_tga_with_rle; +#endif + +#ifndef STBI_WRITE_NO_STDIO +STBIWDEF int stbi_write_png(char const *filename, int w, int h, int comp, const void *data, int stride_in_bytes); +STBIWDEF int stbi_write_bmp(char const *filename, int w, int h, int comp, const void *data); +STBIWDEF int stbi_write_tga(char const *filename, int w, int h, int comp, const void *data); +STBIWDEF int stbi_write_hdr(char const *filename, int w, int h, int comp, const float *data); +#endif + +typedef void stbi_write_func(void *context, void *data, int size); + +STBIWDEF int stbi_write_png_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data, int stride_in_bytes); +STBIWDEF int stbi_write_bmp_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data); +STBIWDEF int stbi_write_tga_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data); +STBIWDEF int stbi_write_hdr_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const float *data); + +#ifdef __cplusplus +} +#endif + +#endif//INCLUDE_STB_IMAGE_WRITE_H + +#ifdef STB_IMAGE_WRITE_IMPLEMENTATION + +#ifdef _WIN32 + #ifndef _CRT_SECURE_NO_WARNINGS + #define _CRT_SECURE_NO_WARNINGS + #endif + #ifndef _CRT_NONSTDC_NO_DEPRECATE + #define _CRT_NONSTDC_NO_DEPRECATE + #endif +#endif + +#ifndef STBI_WRITE_NO_STDIO +#include +#endif // STBI_WRITE_NO_STDIO + +#include +#include +#include +#include + +#if defined(STBIW_MALLOC) && defined(STBIW_FREE) && (defined(STBIW_REALLOC) || defined(STBIW_REALLOC_SIZED)) +// ok +#elif !defined(STBIW_MALLOC) && !defined(STBIW_FREE) && !defined(STBIW_REALLOC) && !defined(STBIW_REALLOC_SIZED) +// ok +#else +#error "Must define all or none of STBIW_MALLOC, STBIW_FREE, and STBIW_REALLOC (or STBIW_REALLOC_SIZED)." +#endif + +#ifndef STBIW_MALLOC +#define STBIW_MALLOC(sz) malloc(sz) +#define STBIW_REALLOC(p,newsz) realloc(p,newsz) +#define STBIW_FREE(p) free(p) +#endif + +#ifndef STBIW_REALLOC_SIZED +#define STBIW_REALLOC_SIZED(p,oldsz,newsz) STBIW_REALLOC(p,newsz) +#endif + + +#ifndef STBIW_MEMMOVE +#define STBIW_MEMMOVE(a,b,sz) memmove(a,b,sz) +#endif + + +#ifndef STBIW_ASSERT +#include +#define STBIW_ASSERT(x) assert(x) +#endif + +#define STBIW_UCHAR(x) (unsigned char) ((x) & 0xff) + +typedef struct +{ + stbi_write_func *func; + void *context; +} stbi__write_context; + +// initialize a callback-based context +static void stbi__start_write_callbacks(stbi__write_context *s, stbi_write_func *c, void *context) +{ + s->func = c; + s->context = context; +} + +#ifndef STBI_WRITE_NO_STDIO + +static void stbi__stdio_write(void *context, void *data, int size) +{ + fwrite(data,1,size,(FILE*) context); +} + +static int stbi__start_write_file(stbi__write_context *s, const char *filename) +{ + FILE *f = fopen(filename, "wb"); + stbi__start_write_callbacks(s, stbi__stdio_write, (void *) f); + return f != NULL; +} + +static void stbi__end_write_file(stbi__write_context *s) +{ + fclose((FILE *)s->context); +} + +#endif // !STBI_WRITE_NO_STDIO + +typedef unsigned int stbiw_uint32; +typedef int stb_image_write_test[sizeof(stbiw_uint32)==4 ?

should be asked either in the [support +section](http://discourse.glfw.org/c/support) of the forum, under the [Stack +Overflow tag](https://stackoverflow.com/questions/tagged/glfw) or [Game +Development tag](https://gamedev.stackexchange.com/questions/tagged/glfw) on +Stack Exchange or in the IRC channel `#glfw` on +[Freenode](http://freenode.net/). + +Questions about the design or implementation of GLFW or about future plans +should be asked in the [dev section](http://discourse.glfw.org/c/dev) of the +forum or in the IRC channel. Please don't open a GitHub issue to discuss design +questions without first checking with a maintainer. + + +## Reporting a bug + +If GLFW is behaving unexpectedly at run-time, start by setting an [error +callback](http://www.glfw.org/docs/latest/intro_guide.html#error_handling). +GLFW will often tell you the cause of an error via this callback. If it +doesn't, that might be a separate bug. + +If GLFW is crashing or triggering asserts, make sure that all your object +handles and other pointers are valid. + +For bugs where it makes sense, a short, self contained example is absolutely +invaluable. Just put it inline in the body text. Note that if the bug is +reproducible with one of the test programs that come with GLFW, just mention +that instead. + +__Don't worry about adding too much information__. Unimportant information can +be abbreviated or removed later, but missing information can stall bug fixing, +especially when your schedule doesn't align with that of the maintainer. + +__Please provide text as text, not as images__. This includes code, error +messages and any other text. Text in images cannot be found by other users +searching for the same problem and may have to be re-typed by maintainers when +debugging. + +You don't need to manually indent your code or other text to quote it with +GitHub Markdown; just surround it with triple backticks: + + ``` + Some quoted text. + ``` + +You can also add syntax highlighting by appending the common file extension: + + ```c + int five(void) + { + return 5; + } + ``` + +There are issue labels for both platforms and GPU manufacturers, so there is no +need to mention these in the subject line. If you do, it will be removed when +the issue is labeled. + +If your bug is already reported, please add any new information you have, or if +it already has everything, give it a :+1:. + + +### Reporting a compile or link bug + +__Note:__ GLFW needs many system APIs to do its job, which on some platforms +means linking to many system libraries. If you are using GLFW as a static +library, that means your application needs to link to these in addition to GLFW. + +__Note:__ Check the [Compiling +GLFW](http://www.glfw.org/docs/latest/compile.html) guide and or [Building +applications](http://www.glfw.org/docs/latest/build.html) guide for before +opening an issue of this kind. Most issues are caused by a missing package or +linker flag. + +Always include the __operating system name and version__ (e.g. `Windows +7 64-bit` or `Ubuntu 15.10`) and the __compiler name and version__ (e.g. `Visual +C++ 2015 Update 2`). If you are using an official release of GLFW, +include the __GLFW release version__ (e.g. `3.1.2`), otherwise include the +__GLFW commit ID__ (e.g. `3795d78b14ef06008889cc422a1fb8d642597751`) from Git. + +Please also include the __complete build log__ from your compiler and linker, +even if it's long. It can always be shortened later, if necessary. + + +#### Quick template + +``` +OS and version: +Compiler version: +Release or commit: +Build log: +``` + + +### Reporting a segfault or other crash bug + +Always include the __operating system name and version__ (e.g. `Windows +7 64-bit` or `Ubuntu 15.10`). If you are using an official release of GLFW, +include the __GLFW release version__ (e.g. `3.1.2`), otherwise include the +__GLFW commit ID__ (e.g. `3795d78b14ef06008889cc422a1fb8d642597751`) from Git. + +Please also include any __error messages__ provided to your application via the +[error +callback](http://www.glfw.org/docs/latest/intro_guide.html#error_handling) and +the __full call stack__ of the crash, or if the crash does not occur in debug +mode, mention that instead. + + +#### Quick template + +``` +OS and version: +Release or commit: +Error messages: +Call stack: +``` + + +### Reporting a context creation bug + +__Note:__ Windows ships with graphics drivers that do not support OpenGL. If +GLFW says that your machine lacks support for OpenGL, it very likely does. +Install drivers from the computer manufacturer or graphics card manufacturer +([Nvidia](http://www.geforce.com/drivers), +[AMD](http://support.amd.com/en-us/download), +[Intel](https://www-ssl.intel.com/content/www/us/en/support/detect.html)) to +fix this. + +__Note:__ AMD only supports OpenGL ES on Windows via EGL. See the +[GLFW\_CONTEXT\_CREATION\_API](http://www.glfw.org/docs/latest/window_guide.html#window_hints_ctx) +hint for how to select EGL. + +Please verify that context creation also fails with the `glfwinfo` tool before +reporting it as a bug. This tool is included in the GLFW source tree as +`tests/glfwinfo.c` and is built along with the library. It has switches for all +GLFW context and framebuffer hints. Run `glfwinfo -h` for a complete list. + +Always include the __operating system name and version__ (e.g. `Windows +7 64-bit` or `Ubuntu 15.10`). If you are using an official release of GLFW, +include the __GLFW release version__ (e.g. `3.1.2`), otherwise include the +__GLFW commit ID__ (e.g. `3795d78b14ef06008889cc422a1fb8d642597751`) from Git. + +If you are running your program in a virtual machine, please mention this and +include the __VM name and version__ (e.g. `VirtualBox 5.1`). + +Please also include the __GLFW version string__ (`3.2.0 X11 EGL clock_gettime +/dev/js`), as described +[here](http://www.glfw.org/docs/latest/intro.html#intro_version_string), the +__GPU model and driver version__ (e.g. `GeForce GTX660 with 352.79`), and the +__output of `glfwinfo`__ (with switches matching any hints you set in your +code) when reporting this kind of bug. If this tool doesn't run on the machine, +mention that instead. + + +#### Quick template + +``` +OS and version: +GPU and driver: +Release or commit: +Version string: +glfwinfo output: +``` + + +### Reporting a monitor or video mode bug + +__Note:__ On headless systems on some platforms, no monitors are reported. This +causes glfwGetPrimaryMonitor to return `NULL`, which not all applications are +prepared for. + +__Note:__ Some third-party tools report more video modes than are approved of +by the OS. For safety and compatibility, GLFW only reports video modes the OS +wants programs to use. This is not a bug. + +The `monitors` tool is included in the GLFW source tree as `tests/monitors.c` +and is built along with the library. It lists all information GLFW provides +about monitors it detects. + +Always include the __operating system name and version__ (e.g. `Windows +7 64-bit` or `Ubuntu 15.10`). If you are using an official release of GLFW, +include the __GLFW release version__ (e.g. `3.1.2`), otherwise include the +__GLFW commit ID__ (e.g. `3795d78b14ef06008889cc422a1fb8d642597751`) from Git. + +If you are running your program in a virtual machine, please mention this and +include the __VM name and version__ (e.g. `VirtualBox 5.1`). + +Please also include any __error messages__ provided to your application via the +[error +callback](http://www.glfw.org/docs/latest/intro_guide.html#error_handling) and +the __output of `monitors`__ when reporting this kind of bug.

This is not a bug. Set a [refresh +callback](http://www.glfw.org/docs/latest/window.html#window_refresh) if you +want to keep the window contents updated during a move or size operation. + +The `events` tool is included in the GLFW source tree as `tests/events.c` and is +built along with the library. It prints all information provided to every +callback supported by GLFW as events occur. Each event is listed with the time +and a unique number to make discussions about event logs easier. The tool has +command-line options for creating multiple windows and full screen windows. + +Always include the __operating system name and version__ (e.g. `Windows +7 64-bit` or `Ubuntu 15.10`). If you are using an official release of GLFW, +include the __GLFW release version__ (e.g. `3.1.2`), otherwise include the +__GLFW commit ID__ (e.g. `3795d78b14ef06008889cc422a1fb8d642597751`) from Git. + +If you are running your program in a virtual machine, please mention this and +include the __VM name and version__ (e.g. `VirtualBox 5.1`). + +Please also include any __error messages__ provided to your application via the +[error +callback](http://www.glfw.org/docs/latest/intro_guide.html#error_handling) and +if relevant, the __output of `events`__ when reporting this kind of bug.

It assumes basic +understanding of how to compile and link a C program as well as how to use the +specific compiler of your chosen development environment. The compilation +and linking process should be explained in your C programming material and in +the documentation for your development environment. + + +@section build_include Including the GLFW header file + +You should include the GLFW header in the source files where you use OpenGL or +GLFW. + +@code +#include +@endcode + +This header declares the GLFW API and by default also includes the OpenGL header +from your development environment. See below for how to control this. + +The GLFW header also defines any platform-specific macros needed by your OpenGL +header, so it can be included without needing any window system headers. + +For example, under Windows you are normally required to include `windows.h` +before the OpenGL header, which would bring in the whole Win32 API. The GLFW +header duplicates the small number of macros needed. + +It does this only when needed, so if `windows.h` _is_ included, the GLFW header +does not try to redefine those symbols. The reverse is not true, i.e. +`windows.h` cannot cope if any of its symbols have already been defined. + +In other words: + + - Do _not_ include the OpenGL headers yourself, as GLFW does this for you + - Do _not_ include `windows.h` or other platform-specific headers unless you + plan on using those APIs directly + - If you _do_ need to include such headers, do it _before_ including + the GLFW header and it will handle this + +If you are using an OpenGL extension loading library such as +[glad](https://github.com/Dav1dde/glad), the extension loader header should +be included _before_ the GLFW one. + +@code +#include +#include +@endcode + +Alternatively the @ref GLFW_INCLUDE_NONE macro (described below) can be used to +prevent the GLFW header from including the OpenGL header. + +@code +#define GLFW_INCLUDE_NONE +#include +#include +@endcode + + +@subsection build_macros GLFW header option macros + +These macros may be defined before the inclusion of the GLFW header and affect +its behavior. + +@anchor GLFW_DLL +__GLFW_DLL__ is required on Windows when using the GLFW DLL, to tell the +compiler that the GLFW functions are defined in a DLL. + +The following macros control which OpenGL or OpenGL ES API header is included. +Only one of these may be defined at a time. + +@anchor GLFW_INCLUDE_GLCOREARB +__GLFW_INCLUDE_GLCOREARB__ makes the GLFW header include the modern +`GL/glcorearb.h` header (`OpenGL/gl3.h` on macOS) instead of the regular OpenGL +header. + +@anchor GLFW_INCLUDE_ES1 +__GLFW_INCLUDE_ES1__ makes the GLFW header include the OpenGL ES 1.x `GLES/gl.h` +header instead of the regular OpenGL header. + +@anchor GLFW_INCLUDE_ES2 +__GLFW_INCLUDE_ES2__ makes the GLFW header include the OpenGL ES 2.0 +`GLES2/gl2.h` header instead of the regular OpenGL header. + +@anchor GLFW_INCLUDE_ES3 +__GLFW_INCLUDE_ES3__ makes the GLFW header include the OpenGL ES 3.0 +`GLES3/gl3.h` header instead of the regular OpenGL header. + +@anchor GLFW_INCLUDE_ES31 +__GLFW_INCLUDE_ES31__ makes the GLFW header include the OpenGL ES 3.1 +`GLES3/gl31.h` header instead of the regular OpenGL header. + +@anchor GLFW_INCLUDE_ES32 +__GLFW_INCLUDE_ES31__ makes the GLFW header include the OpenGL ES 3.2 +`GLES3/gl32.h` header instead of the regular OpenGL header. + +@anchor GLFW_INCLUDE_NONE +__GLFW_INCLUDE_NONE__ makes the GLFW header not include any OpenGL or OpenGL ES +API header. This is useful in combination with an extension loading library. + +If none of the above inclusion macros are defined, the standard OpenGL `GL/gl.h` +header (`OpenGL/gl.h` on macOS) is included. + +The following macros control the inclusion of additional API headers. Any +number of these may be defined simultaneously, and/or together with one of the +above macros. + +@anchor GLFW_INCLUDE_VULKAN +__GLFW_INCLUDE_VULKAN__ makes the GLFW header include the Vulkan +`vulkan/vulkan.h` header in addition to any selected OpenGL or OpenGL ES header. + +@anchor GLFW_INCLUDE_GLEXT +__GLFW_INCLUDE_GLEXT__ makes the GLFW header include the appropriate extension +header for the OpenGL or OpenGL ES header selected above after and in addition +to that header. + +@anchor GLFW_INCLUDE_GLU +__GLFW_INCLUDE_GLU__ makes the header include the GLU header in addition to the +header selected above. This should only be used with the standard OpenGL header +and only for compatibility with legacy code. GLU has been deprecated and should +not be used in new code. + +@note GLFW does not provide any of the API headers mentioned above. They must +be provided by your development environment or your OpenGL, OpenGL ES or Vulkan +SDK. + +@note None of these macros may be defined during the compilation of GLFW itself. +If your build includes GLFW and you define any these in your build files, make +sure they are not applied to the GLFW sources. + + +@section build_link Link with the right libraries + +GLFW is essentially a wrapper of various platform-specific APIs and therefore +needs to link against many different system libraries. If you are using GLFW as +a shared library / dynamic library / DLL then it takes care of these links. +However, if you are using GLFW as a static library then your executable will +need to link against these libraries. + +On Windows and macOS, the list of system libraries is static and can be +hard-coded into your build environment. See the section for your development +environment below. On Linux and other Unix-like operating systems, the list +varies but can be retrieved in various ways as described below. + +A good general introduction to linking is +[Beginner's Guide to Linkers](http://www.lurklurk.org/linkers/linkers.html) by +David Drysdale. + + +@subsection build_link_win32 With MinGW or Visual C++ on Windows + +The static version of the GLFW library is named `glfw3`. When using this +version, it is also necessary to link with some libraries that GLFW uses. + +When linking an application under Windows that uses the static version of GLFW, +you must link with `opengl32`. On some versions of MinGW, you must also +explicitly link with `gdi32`, while other versions of MinGW include it in the +set of default libraries along with other dependencies like `user32` and +`kernel32`. If you are using GLU, you must also link with `glu32`. + +The link library for the GLFW DLL is named `glfw3dll`. When compiling an +application that uses the DLL version of GLFW, you need to define the @ref +GLFW_DLL macro _before_ any inclusion of the GLFW header. This can be done +either with a compiler switch or by defining it in your source code. + +An application using the GLFW DLL does not need to link against any of its +dependencies, but you still have to link against `opengl32` if your application +uses OpenGL and `glu32` if it uses GLU. + + +@subsection build_link_cmake_source With CMake and GLFW source + +This section is about using CMake to compile and link GLFW along with your +application. If you want to use an installed binary instead, see @ref +build_link_cmake_package. + +With a few changes to your `CMakeLists.txt` you can have the GLFW source tree +built along with your application. + +When including GLFW as part of your build, you probably don't want to build the +GLFW tests, examples and documentation.

In order for applications +and window managers to work well together, a number of standards and +conventions have been developed that regulate behavior outside the scope of the +X11 API; most importantly the +[Inter-Client Communication Conventions Manual](http://www.tronche.com/gui/x/icccm/) +(ICCCM) and +[Extended Window Manager Hints](http://standards.freedesktop.org/wm-spec/wm-spec-latest.html) +(EWMH) standards. + +GLFW uses the `_MOTIF_WM_HINTS` window property to support borderless windows. +If the running window manager does not support this property, the +`GLFW_DECORATED` hint will have no effect. + +GLFW uses the ICCCM `WM_DELETE_WINDOW` protocol to intercept the user +attempting to close the GLFW window. If the running window manager does not +support this protocol, the close callback will never be called. + +GLFW uses the EWMH `_NET_WM_PING` protocol, allowing the window manager notify +the user when the application has stopped responding, i.e. when it has ceased to +process events. If the running window manager does not support this protocol, +the user will not be notified if the application locks up. + +GLFW uses the EWMH `_NET_WM_STATE_FULLSCREEN` window state to tell the window +manager to make the GLFW window full screen. If the running window manager does +not support this state, full screen windows may not work properly. GLFW has +a fallback code path in case this state is unavailable, but every window manager +behaves slightly differently in this regard. + +GLFW uses the EWMH `_NET_WM_BYPASS_COMPOSITOR` window property to tell a +compositing window manager to un-redirect full screen GLFW windows. If the +running window manager uses compositing but does not support this property then +additional copying may be performed for each buffer swap of full screen windows. + +GLFW uses the +[clipboard manager protocol](http://www.freedesktop.org/wiki/ClipboardManager/) +to push a clipboard string (i.e. selection) owned by a GLFW window about to be +destroyed to the clipboard manager. If there is no running clipboard manager, +the clipboard string will be unavailable once the window has been destroyed. + +GLFW uses the +[X drag-and-drop protocol](http://www.freedesktop.org/wiki/Specifications/XDND/) +to provide file drop events. If the application originating the drag does not +support this protocol, drag and drop will not work. + +GLFW uses the XRandR 1.3 extension to provide multi-monitor support. If the +running X server does not support this version of this extension, multi-monitor +support will not function and only a single, desktop-spanning monitor will be +reported. + +GLFW uses the XRandR 1.3 and Xf86vidmode extensions to provide gamma ramp +support.

Most of the features are provided by the core protocol, +while cursor support is provided by the libwayland-cursor helper library, EGL +integration by libwayland-egl, and keyboard handling by +[libxkbcommon](https://xkbcommon.org/). In addition, GLFW uses some protocols +from wayland-protocols to provide additional features if the compositor +supports them. + +GLFW uses xkbcommon 0.5.0 to provide compose key support. When it has been +built against an older xkbcommon, the compose key will be disabled even if it +has been configured in the compositor. + +GLFW uses the [xdg-shell +protocol](https://cgit.freedesktop.org/wayland/wayland-protocols/tree/stable/xdg-shell/xdg-shell.xml) +to provide better window management. This protocol is part of +wayland-protocols 1.12, and mandatory at build time. If the running compositor +does not support this protocol, the older [wl_shell +interface](https://cgit.freedesktop.org/wayland/wayland/tree/protocol/wayland.xml#n972) +will be used instead. This will result in a worse integration with the +desktop, especially on tiling compositors. + +GLFW uses the [relative pointer +protocol](https://cgit.freedesktop.org/wayland/wayland-protocols/tree/unstable/relative-pointer/relative-pointer-unstable-v1.xml) +alongside the [pointer constraints +protocol](https://cgit.freedesktop.org/wayland/wayland-protocols/tree/unstable/pointer-constraints/pointer-constraints-unstable-v1.xml) +to implement disabled cursor. These two protocols are part of +wayland-protocols 1.1, and mandatory at build time. If the running compositor +does not support both of these protocols, disabling the cursor will have no +effect. + +GLFW uses the [idle inhibit +protocol](https://cgit.freedesktop.org/wayland/wayland-protocols/tree/unstable/idle-inhibit/idle-inhibit-unstable-v1.xml) +to prohibit the screensaver from starting. This protocol is part of +wayland-protocols 1.6, and mandatory at build time.

Where this extension is unavailable, setting the +`GLFW_OPENGL_PROFILE` hint to anything but `GLFW_OPENGL_ANY_PROFILE`, or setting +`GLFW_CLIENT_API` to anything but `GLFW_OPENGL_API` or `GLFW_NO_API` will cause +@ref glfwCreateWindow to fail. + +GLFW uses the `GLX_ARB_context_flush_control` extension to provide control over +whether a context is flushed when it is released (made non-current). Where this +extension is unavailable, the `GLFW_CONTEXT_RELEASE_BEHAVIOR` hint will have no +effect and the context will always be flushed when released. + +GLFW uses the `GLX_ARB_framebuffer_sRGB` and `GLX_EXT_framebuffer_sRGB` +extensions to provide support for sRGB framebuffers.

If both are available, the EXT one is preferred. If +neither is available, no other extensions are used and many GLFW features +related to context creation will have no effect or cause errors when used. + +GLFW uses the `WGL_EXT_swap_control` extension to provide vertical retrace +synchronization (or _vsync_).

There is also still no mechanism for requesting debug +contexts or no-error contexts. Versions of Mac OS X earlier than 10.7 support +at most OpenGL version 2.1. + +Because of this, on OS X 10.7 and later, the `GLFW_CONTEXT_VERSION_MAJOR` and +`GLFW_CONTEXT_VERSION_MINOR` hints will cause @ref glfwCreateWindow to fail if +given version 3.0 or 3.1. The `GLFW_OPENGL_FORWARD_COMPAT` hint must be set to +`GLFW_TRUE` and the `GLFW_OPENGL_PROFILE` hint must be set to +`GLFW_OPENGL_CORE_PROFILE` when creating OpenGL 3.2 and later contexts. The +`GLFW_OPENGL_DEBUG_CONTEXT` and `GLFW_CONTEXT_NO_ERROR` hints are ignored. + +Also, on Mac OS X 10.6 and below, the `GLFW_CONTEXT_VERSION_MAJOR` and +`GLFW_CONTEXT_VERSION_MINOR` hints will fail if given a version above 2.1, +setting the `GLFW_OPENGL_PROFILE` or `GLFW_OPENGL_FORWARD_COMPAT` hints to +a non-default value will cause @ref glfwCreateWindow to fail and the +`GLFW_OPENGL_DEBUG_CONTEXT` hint is ignored. + + +@section compat_vulkan Vulkan loader and API + +By default, GLFW uses the standard system-wide Vulkan loader to access the +Vulkan API on all platforms except macOS.

CMake needs to know two +paths for this: the path to the _root_ directory of the GLFW source tree (i.e. +_not_ the `src` subdirectory) and the target path for the generated files and +compiled binaries. If these are the same, it is called an in-tree build, +otherwise it is called an out-of-tree build. + +One of several advantages of out-of-tree builds is that you can generate files +and compile for different development environments using a single source tree. + +@note This section is about generating the project files or makefiles necessary +to compile the GLFW library, not about compiling the actual library. + + +@subsubsection compile_generate_cli Generating files with the CMake command-line tool + +To make an in-tree build, enter the _root_ directory of the GLFW source tree +(i.e. _not_ the `src` subdirectory) and run CMake.

The options are: + + - @b _GLFW_COCOA to use the Cocoa frameworks + - @b _GLFW_WIN32 to use the Win32 API + - @b _GLFW_X11 to use the X Window System + - @b _GLFW_WAYLAND to use the Wayland API (experimental and incomplete) + - @b _GLFW_MIR to use the Mir API (experimental and incomplete) + - @b _GLFW_OSMESA to use the OSMesa API (headless and non-interactive) + +If you are building GLFW as a shared library / dynamic library / DLL then you +must also define @b _GLFW_BUILD_DLL. Otherwise, you must not define it. + +If you are linking the Vulkan loader statically into your application then you +must also define @b _GLFW_VULKAN_STATIC. Otherwise, GLFW will attempt to use the +external version. + +If you are using a custom name for the Vulkan, EGL, GLX, OSMesa, OpenGL, GLESv1 +or GLESv2 library, you can override the default names by defining those you need +of @b _GLFW_VULKAN_LIBRARY, @b _GLFW_EGL_LIBRARY, @b _GLFW_GLX_LIBRARY, @b +_GLFW_OSMESA_LIBRARY, @b _GLFW_OPENGL_LIBRARY, @b _GLFW_GLESV1_LIBRARY and @b +_GLFW_GLESV2_LIBRARY.

See +[context related hints](@ref window_hints_ctx) in the window guide. + + +@subsection context_sharing Context object sharing + +When creating a window and its OpenGL or OpenGL ES context with @ref +glfwCreateWindow, you can specify another window whose context the new one +should share its objects (textures, vertex and element buffers, etc.) with. + +@code +GLFWwindow* second_window = glfwCreateWindow(640, 480, "Second Window", NULL, first_window); +@endcode + +Object sharing is implemented by the operating system and graphics driver. On +platforms where it is possible to choose which types of objects are shared, GLFW +requests that all types are shared. + +See the relevant chapter of the [OpenGL](https://www.opengl.org/registry/) or +[OpenGL ES](http://www.khronos.org/opengles/) reference documents for more +information. The name and number of this chapter unfortunately varies between +versions and APIs, but has at times been named _Shared Objects and Multiple +Contexts_. + +GLFW comes with a barebones object sharing example program called `sharing`. + + +@subsection context_offscreen Offscreen contexts + +GLFW doesn't support creating contexts without an associated window. However, +contexts with hidden windows can be created with the +[GLFW_VISIBLE](@ref GLFW_VISIBLE_hint) window hint. + +@code +glfwWindowHint(GLFW_VISIBLE, GLFW_FALSE); + +GLFWwindow* offscreen_context = glfwCreateWindow(640, 480, "", NULL, NULL); +@endcode + +The window never needs to be shown and its context can be used as a plain +offscreen context. Depending on the window manager, the size of a hidden +window's framebuffer may not be usable or modifiable, so framebuffer +objects are recommended for rendering with such contexts. + +You should still [process events](@ref events) as long as you have at least one +window, even if none of them are visible. + +@macos The first time a window is created the menu bar is created. This is not +desirable for example when writing a command-line only application. Menu bar +creation can be disabled with the @ref GLFW_COCOA_MENUBAR init hint. + + +@subsection context_less Windows without contexts + +You can disable context creation by setting the +[GLFW_CLIENT_API](@ref GLFW_CLIENT_API_hint) hint to `GLFW_NO_API`. Windows +without contexts must not be passed to @ref glfwMakeContextCurrent or @ref +glfwSwapBuffers. + + +@section context_current Current context + +Before you can make OpenGL or OpenGL ES calls, you need to have a current +context of the correct type. A context can only be current for a single thread +at a time, and a thread can only have a single context current at a time. + +When moving a context between threads, you must make it non-current on the old +thread before making it current on the new one. + +The context of a window is made current with @ref glfwMakeContextCurrent. + +@code +glfwMakeContextCurrent(window); +@endcode + +The window of the current context is returned by @ref glfwGetCurrentContext. + +@code +GLFWwindow* window = glfwGetCurrentContext(); +@endcode + +The following GLFW functions require a context to be current. Calling any these +functions without a current context will generate a @ref GLFW_NO_CURRENT_CONTEXT +error. + + - @ref glfwSwapInterval + - @ref glfwExtensionSupported + - @ref glfwGetProcAddress + + +@section context_swap Buffer swapping + +See @ref buffer_swap in the window guide. + + +@section context_glext OpenGL and OpenGL ES extensions + +One of the benefits of OpenGL and OpenGL ES is their extensibility. +Hardware vendors may include extensions in their implementations that extend the +API before that functionality is included in a new version of the OpenGL or +OpenGL ES specification, and some extensions are never included and remain +as extensions until they become obsolete. + +An extension is defined by: + +- An extension name (e.g. `GL_ARB_debug_output`) +- New OpenGL tokens (e.g. `GL_DEBUG_SEVERITY_HIGH_ARB`) +- New OpenGL functions (e.g. `glGetDebugMessageLogARB`) + +Note the `ARB` affix, which stands for Architecture Review Board and is used +for official extensions. The extension above was created by the ARB, but there +are many different affixes, like `NV` for Nvidia and `AMD` for, well, AMD. Any +group may also use the generic `EXT` affix. Lists of extensions, together with +their specifications, can be found at the +[OpenGL Registry](http://www.opengl.org/registry/) and +[OpenGL ES Registry](https://www.khronos.org/registry/gles/). + + +@subsection context_glext_auto Loading extension with a loader library + +An extension loader library is the easiest and best way to access both OpenGL and +OpenGL ES extensions and modern versions of the core OpenGL or OpenGL ES APIs. +They will take care of all the details of declaring and loading everything you +need. One such library is [glad](https://github.com/Dav1dde/glad) and there are +several others. + +The following example will use glad but all extension loader libraries work +similarly. + +First you need to generate the source files using the glad Python script. This +example generates a loader for any version of OpenGL, which is the default for +both GLFW and glad, but loaders for OpenGL ES, as well as loaders for specific +API versions and extension sets can be generated. The generated files are +written to the `output` directory. + +@code{.sh} +python main.py --generator c --no-loader --out-path output +@endcode + +The `--no-loader` option is added because GLFW already provides a function for +loading OpenGL and OpenGL ES function pointers, one that automatically uses the +selected context creation API, and glad can call this instead of having to +implement its own. There are several other command-line options as well. See +the glad documentation for details. + +Add the generated `output/src/glad.c`, `output/include/glad/glad.h` and +`output/include/KHR/khrplatform.h` files to your build. Then you need to +include the glad header file, which will replace the OpenGL header of your +development environment. By including the glad header before the GLFW header, +it suppresses the development environment's OpenGL or OpenGL ES header. + +@code +#include +#include +@endcode + +Finally you need to initialize glad once you have a suitable current context. + +@code +window = glfwCreateWindow(640, 480, "My Window", NULL, NULL); +if (!window) +{ + ... +} + +glfwMakeContextCurrent(window); + +gladLoadGLLoader((GLADloadproc) glfwGetProcAddress); +@endcode + +Once glad has been loaded, you have access to all OpenGL core and extension +functions supported by both the context you created and the glad loader you +generated and you are ready to start rendering. + +You can specify a minimum required OpenGL or OpenGL ES version with +[context hints](@ref window_hints_ctx). If your needs are more complex, you can +check the actual OpenGL or OpenGL ES version with +[context attributes](@ref window_attribs_ctx), or you can check whether +a specific version is supported by the current context with the +`GLAD_GL_VERSION_x_x` booleans. + +@code +if (GLAD_GL_VERSION_3_2) +{ + // Call OpenGL 3.2+ specific code +} +@endcode + +To check whether a specific extension is supported, use the `GLAD_GL_xxx` +booleans. + +@code +if (GLAD_GL_ARB_debug_output) +{ + // Use GL_ARB_debug_output +} +@endcode + + +@subsection context_glext_manual Loading extensions manually + +__Do not use this technique__ unless it is absolutely necessary. An +[extension loader library](@ref context_glext_auto) will save you a ton of +tedious, repetitive, error prone work. + +To use a certain extension, you must first check whether the context supports +that extension and then, if it introduces new functions, retrieve the pointers +to those functions. GLFW provides @ref glfwExtensionSupported and @ref +glfwGetProcAddress for manual loading of extensions and new API functions. + +This section will demonstrate manual loading of OpenGL extensions. The loading +of OpenGL ES extensions is identical except for the name of the extension header. + + +@subsubsection context_glext_header The glext.h header + +The `glext.h` extension header is a continually updated file that defines the +interfaces for all OpenGL extensions. The latest version of this can always be +found at the [OpenGL Registry](http://www.opengl.org/registry/). There are also +extension headers for the various versions of OpenGL ES at the +[OpenGL ES Registry](https://www.khronos.org/registry/gles/). It it strongly +recommended that you use your own copy of the extension header, as the one +included in your development environment may be several years out of date and +may not include the extensions you wish to use. + +The header defines function pointer types for all functions of all extensions it +supports. These have names like `PFNGLGETDEBUGMESSAGELOGARBPROC` (for +`glGetDebugMessageLogARB`), i.e. the name is made uppercase and `PFN` (pointer +to function) and `PROC` (procedure) are added to the ends. + +To include the extension header, define @ref GLFW_INCLUDE_GLEXT before including +the GLFW header. + +@code +#define GLFW_INCLUDE_GLEXT +#include +@endcode + + +@subsubsection context_glext_string Checking for extensions + +A given machine may not actually support the extension (it may have older +drivers or a graphics card that lacks the necessary hardware features), so it +is necessary to check at run-time whether the context supports the extension. +This is done with @ref glfwExtensionSupported. + +@code +if (glfwExtensionSupported("GL_ARB_debug_output")) +{ + // The extension is supported by the current context +} +@endcode + +The argument is a null terminated ASCII string with the extension name. If the +extension is supported, @ref glfwExtensionSupported returns `GLFW_TRUE`, +otherwise it returns `GLFW_FALSE`. + + +@subsubsection context_glext_proc Fetching function pointers + +Many extensions, though not all, require the use of new OpenGL functions. +These functions often do not have entry points in the client API libraries of +your operating system, making it necessary to fetch them at run time. You can +retrieve pointers to these functions with @ref glfwGetProcAddress. + +@code +PFNGLGETDEBUGMESSAGELOGARBPROC pfnGetDebugMessageLog = glfwGetProcAddress("glGetDebugMessageLogARB"); +@endcode + +In general, you should avoid giving the function pointer variables the (exact) +same name as the function, as this may confuse your linker. Instead, you can +use a different prefix, like above, or some other naming scheme. + +Now that all the pieces have been introduced, here is what they might look like +when used together. + +@code +#define GLFW_INCLUDE_GLEXT +#include + +#define glGetDebugMessageLogARB pfnGetDebugMessageLog +PFNGLGETDEBUGMESSAGELOGARBPROC pfnGetDebugMessageLog; + +// Flag indicating whether the extension is supported +int has_ARB_debug_output = 0; + +void load_extensions(void) +{ + if (glfwExtensionSupported("GL_ARB_debug_output")) + { + pfnGetDebugMessageLog = (PFNGLGETDEBUGMESSAGELOGARBPROC) + glfwGetProcAddress("glGetDebugMessageLogARB"); + has_ARB_debug_output = 1; + } +} + +void some_function(void) +{ + if (has_ARB_debug_output) + { + // Now the extension function can be called as usual + glGetDebugMessageLogARB(...); + } +} +@endcode + +*/ diff --git a/src/lib/third_party/glfw/OLD/docs/extra.css b/src/lib/third_party/glfw/OLD/docs/extra.css new file mode 100644 index

For details on +a specific function in this category, see the @ref input. There are also guides +for the other areas of GLFW. + + - @ref intro_guide + - @ref window_guide + - @ref context_guide + - @ref vulkan_guide + - @ref monitor_guide + +GLFW provides many kinds of input. While some can only be polled, like time, or +only received via callbacks, like scrolling, many provide both callbacks and +polling. Callbacks are more work to use than polling but is less CPU intensive +and guarantees that you do not miss state changes. + +All input callbacks receive a window handle. By using the +[window user pointer](@ref window_userptr), you can access non-global structures +or objects from your callbacks. + +To get a better feel for how the various events callbacks behave, run the +`events` test program. It register every callback supported by GLFW and prints +out all arguments provided for every event, along with time and sequence +information. + + +@section events Event processing + +GLFW needs to poll the window system for events both to provide input to the +application and to prove to the window system that the application hasn't locked +up. Event processing is normally done each frame after +[buffer swapping](@ref buffer_swap). Even when you have no windows, event +polling needs to be done in order to receive monitor and joystick connection +events. + +There are three functions for processing pending events. @ref glfwPollEvents, +processes only those events that have already been received and then returns +immediately. + +@code +glfwPollEvents(); +@endcode + +This is the best choice when rendering continuously, like most games do. + +If you only need to update the contents of the window when you receive new +input, @ref glfwWaitEvents is a better choice. + +@code +glfwWaitEvents(); +@endcode + +It puts the thread to sleep until at least one event has been received and then +processes all received events. This saves a great deal of CPU cycles and is +useful for, for example, editing tools. There must be at least one GLFW window +for this function to sleep. + +If you want to wait for events but have UI elements or other tasks that need +periodic updates, @ref glfwWaitEventsTimeout lets you specify a timeout. + +@code +glfwWaitEventsTimeout(0.7); +@endcode + +It puts the thread to sleep until at least one event has been received, or until +the specified number of seconds have elapsed. It then processes any received +events. + +If the main thread is sleeping in @ref glfwWaitEvents, you can wake it from +another thread by posting an empty event to the event queue with @ref +glfwPostEmptyEvent. + +@code +glfwPostEmptyEvent(); +@endcode + +Do not assume that callbacks will _only_ be called in response to the above +functions. While it is necessary to process events in one or more of the ways +above, window systems that require GLFW to register callbacks of its own can +pass events to GLFW in response to many window system function calls. GLFW will +pass those events on to the application callbacks before returning. + +For example, on Windows the system function that @ref glfwSetWindowSize is +implemented with will send window size events directly to the event callback +that every window has and that GLFW implements for its windows. If you have set +a [window size callback](@ref window_size) GLFW will call it in turn with the +new size before everything returns back out of the @ref glfwSetWindowSize call. + + +@section input_keyboard Keyboard input + +GLFW divides keyboard input into two categories; key events and character +events. Key events relate to actual physical keyboard keys, whereas character +events relate to the Unicode code points generated by pressing some of them. + +Keys and characters do not map 1:1. A single key press may produce several +characters, and a single character may require several keys to produce. This +may not be the case on your machine, but your users are likely not all using the +same keyboard layout, input method or even operating system as you. + + +@subsection input_key Key input + +If you wish to be notified when a physical key is pressed or released or when it +repeats, set a key callback. + +@code +glfwSetKeyCallback(window, key_callback); +@endcode + +The callback function receives the [keyboard key](@ref keys), platform-specific +scancode, key action and [modifier bits](@ref mods). + +@code +void key_callback(GLFWwindow* window, int key, int scancode, int action, int mods) +{ + if (key == GLFW_KEY_E && action == GLFW_PRESS) + activate_airship(); +} +@endcode + +The action is one of `GLFW_PRESS`, `GLFW_REPEAT` or `GLFW_RELEASE`. The key +will be `GLFW_KEY_UNKNOWN` if GLFW lacks a key token for it, for example +_E-mail_ and _Play_ keys. + +The scancode is unique for every key, regardless of whether it has a key token. +Scancodes are platform-specific but consistent over time, so keys will have +different scancodes depending on the platform but they are safe to save to disk. +You can query the scancode for any [named key](@ref keys) on the current +platform with @ref glfwGetKeyScancode. + +@code +const int scancode = glfwGetKeyScancode(GLFW_KEY_X); +set_key_mapping(scancode, swap_weapons); +@endcode + +The last reported state for every [named key](@ref keys) is also saved in +per-window state arrays that can be polled with @ref glfwGetKey. + +@code +int state = glfwGetKey(window, GLFW_KEY_E); +if (state == GLFW_PRESS) +{ + activate_airship(); +} +@endcode + +The returned state is one of `GLFW_PRESS` or `GLFW_RELEASE`. + +This function only returns cached key event state. It does not poll the +system for the current physical state of the key. + +@anchor GLFW_STICKY_KEYS +Whenever you poll state, you risk missing the state change you are looking for. +If a pressed key is released again before you poll its state, you will have +missed the key press. The recommended solution for this is to use a +key callback, but there is also the `GLFW_STICKY_KEYS` input mode. + +@code +glfwSetInputMode(window, GLFW_STICKY_KEYS, 1); +@endcode + +When sticky keys mode is enabled, the pollable state of a key will remain +`GLFW_PRESS` until the state of that key is polled with @ref glfwGetKey. Once +it has been polled, if a key release event had been processed in the meantime, +the state will reset to `GLFW_RELEASE`, otherwise it will remain `GLFW_PRESS`. + +@anchor GLFW_LOCK_KEY_MODS +If you wish to know what the state of the Caps Lock and Num Lock keys was when +input events were generated, set the `GLFW_LOCK_KEY_MODS` input mode. + +@code +glfwSetInputMode(window, GLFW_LOCK_KEY_MODS, 1); +@endcode + +When this input mode is enabled, any callback that receives +[modifier bits](@ref mods) will have the @ref GLFW_MOD_CAPS_LOCK bit set if Caps +Lock was on when the event occurred and the @ref GLFW_MOD_NUM_LOCK bit set if +Num Lock was on. + +The `GLFW_KEY_LAST` constant holds the highest value of any +[named key](@ref keys). + + +@subsection input_char Text input + +GLFW supports text input in the form of a stream of +[Unicode code points](https://en.wikipedia.org/wiki/Unicode), as produced by the +operating system text input system. Unlike key input, text input obeys keyboard +layouts and modifier keys and supports composing characters using +[dead keys](https://en.wikipedia.org/wiki/Dead_key). Once received, you can +encode the code points into UTF-8 or any other encoding you prefer. + +Because an `unsigned int` is 32 bits long on all platforms supported by GLFW, +you can treat the code point argument as native endian UTF-32. + +If you wish to offer regular text input, set a character callback. + +@code +glfwSetCharCallback(window, character_callback); +@endcode + +The callback function receives Unicode code points for key events that would +have led to regular text input and generally behaves as a standard text field on +that platform. + +@code +void character_callback(GLFWwindow* window, unsigned int codepoint) +{ +} +@endcode + + +@subsection input_key_name Key names + +If you wish to refer to keys by name, you can query the keyboard layout +dependent name of printable keys with @ref glfwGetKeyName. + +@code +const char* key_name = glfwGetKeyName(GLFW_KEY_W, 0); +show_tutorial_hint("Press %s to move forward", key_name); +@endcode + +This function can handle both [keys and scancodes](@ref input_key). If the +specified key is `GLFW_KEY_UNKNOWN` then the scancode is used, otherwise it is +ignored. This matches the behavior of the key callback, meaning the callback +arguments can always be passed unmodified to this function. + + +@section input_mouse Mouse input + +Mouse input comes in many forms, including cursor motion, button presses and +scrolling offsets. The cursor appearance can also be changed, either to +a custom image or a standard cursor shape from the system theme. + + +@subsection cursor_pos Cursor position + +If you wish to be notified when the cursor moves over the window, set a cursor +position callback. + +@code +glfwSetCursorPosCallback(window, cursor_pos_callback); +@endcode + +The callback functions receives the cursor position, measured in screen +coordinates but relative to the top-left corner of the window client area. On +platforms that provide it, the full sub-pixel cursor position is passed on. + +@code +static void cursor_position_callback(GLFWwindow* window, double xpos, double ypos) +{ +} +@endcode + +The cursor position is also saved per-window and can be polled with @ref +glfwGetCursorPos. + +@code +double xpos, ypos; +glfwGetCursorPos(window, &xpos, &ypos); +@endcode + + +@subsection cursor_mode Cursor mode + +@anchor GLFW_CURSOR +The `GLFW_CURSOR` input mode provides several cursor modes for special forms of +mouse motion input. By default, the cursor mode is `GLFW_CURSOR_NORMAL`, +meaning the regular arrow cursor (or another cursor set with @ref glfwSetCursor) +is used and cursor motion is not limited. + +If you wish to implement mouse motion based camera controls or other input +schemes that require unlimited mouse movement, set the cursor mode to +`GLFW_CURSOR_DISABLED`. + +@code +glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_DISABLED); +@endcode + +This will hide the cursor and lock it to the specified window. GLFW will then +take care of all the details of cursor re-centering and offset calculation and +providing the application with a virtual cursor position. This virtual position +is provided normally via both the cursor position callback and through polling. + +@note You should not implement your own version of this functionality using +other features of GLFW. It is not supported and will not work as robustly as +`GLFW_CURSOR_DISABLED`. + +If you only wish the cursor to become hidden when it is over a window but still +want it to behave normally, set the cursor mode to `GLFW_CURSOR_HIDDEN`. + +@code +glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_HIDDEN); +@endcode + +This mode puts no limit on the motion of the cursor. + +To exit out of either of these special modes, restore the `GLFW_CURSOR_NORMAL` +cursor mode. + +@code +glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_NORMAL); +@endcode + + +@subsection cursor_object Cursor objects + +GLFW supports creating both custom and system theme cursor images, encapsulated +as @ref GLFWcursor objects. They are created with @ref glfwCreateCursor or @ref +glfwCreateStandardCursor and destroyed with @ref glfwDestroyCursor, or @ref +glfwTerminate, if any remain. + + +@subsubsection cursor_custom Custom cursor creation + +A custom cursor is created with @ref glfwCreateCursor, which returns a handle to +the created cursor object. For example, this creates a 16x16 white square +cursor with the hot-spot in the upper-left corner: + +@code +unsigned char pixels[16 * 16 * 4]; +memset(pixels, 0xff, sizeof(pixels)); + +GLFWimage image; +image.width = 16; +image.height = 16; +image.pixels = pixels; + +GLFWcursor* cursor = glfwCreateCursor(&image, 0, 0); +@endcode + +If cursor creation fails, `NULL` will be returned, so it is necessary to check +the return value. + +The image data is 32-bit, little-endian, non-premultiplied RGBA, i.e. eight bits +per channel with the red channel first. The pixels are arranged canonically as +sequential rows, starting from the top-left corner. + + +@subsubsection cursor_standard Standard cursor creation + +A cursor with a [standard shape](@ref shapes) from the current system cursor +theme can be can be created with @ref glfwCreateStandardCursor. + +@code +GLFWcursor* cursor = glfwCreateStandardCursor(GLFW_HRESIZE_CURSOR); +@endcode + +These cursor objects behave in the exact same way as those created with @ref +glfwCreateCursor except that the system cursor theme provides the actual image. + + +@subsubsection cursor_destruction Cursor destruction + +When a cursor is no longer needed, destroy it with @ref glfwDestroyCursor. + +@code +glfwDestroyCursor(cursor); +@endcode + +Cursor destruction always succeeds. If the cursor is current for any window, +that window will revert to the default cursor. This does not affect the cursor +mode. All remaining cursors remaining are destroyed when @ref glfwTerminate is +called. + + +@subsubsection cursor_set Cursor setting + +A cursor can be set as current for a window with @ref glfwSetCursor. + +@code +glfwSetCursor(window, cursor); +@endcode + +Once set, the cursor image will be used as long as the system cursor is over the +client area of the window and the [cursor mode](@ref cursor_mode) is set +to `GLFW_CURSOR_NORMAL`. + +A single cursor may be set for any number of windows. + +To revert to the default cursor, set the cursor of that window to `NULL`. + +@code +glfwSetCursor(window, NULL); +@endcode + +When a cursor is destroyed, any window that has it set will revert to the +default cursor. This does not affect the cursor mode. + + +@subsection cursor_enter Cursor enter/leave events + +If you wish to be notified when the cursor enters or leaves the client area of +a window, set a cursor enter/leave callback. + +@code +glfwSetCursorEnterCallback(window, cursor_enter_callback); +@endcode + +The callback function receives the new classification of the cursor. + +@code +void cursor_enter_callback(GLFWwindow* window, int entered) +{ + if (entered) + { + // The cursor entered the client area of the window + } + else + { + // The cursor left the client area of the window + } +} +@endcode + +You can query whether the cursor is currently inside the client area of the +window with the [GLFW_HOVERED](@ref GLFW_HOVERED_attrib) window attribute. + +@code +if (glfwGetWindowAttrib(window, GLFW_HOVERED)) +{ + highlight_interface(); +} +@endcode + + +@subsection input_mouse_button Mouse button input + +If you wish to be notified when a mouse button is pressed or released, set +a mouse button callback. + +@code +glfwSetMouseButtonCallback(window, mouse_button_callback); +@endcode + +The callback function receives the [mouse button](@ref buttons), button action +and [modifier bits](@ref mods). + +@code +void mouse_button_callback(GLFWwindow* window, int button, int action, int mods) +{ + if (button == GLFW_MOUSE_BUTTON_RIGHT && action == GLFW_PRESS) + popup_menu(); +} +@endcode + +The action is one of `GLFW_PRESS` or `GLFW_RELEASE`. + +Mouse button states for [named buttons](@ref buttons) are also saved in +per-window state arrays that can be polled with @ref glfwGetMouseButton. + +@code +int state = glfwGetMouseButton(window, GLFW_MOUSE_BUTTON_LEFT); +if (state == GLFW_PRESS) +{ + upgrade_cow(); +} +@endcode + +The returned state is one of `GLFW_PRESS` or `GLFW_RELEASE`. + +This function only returns cached mouse button event state. It does not poll +the system for the current state of the mouse button. + +@anchor GLFW_STICKY_MOUSE_BUTTONS +Whenever you poll state, you risk missing the state change you are looking for. +If a pressed mouse button is released again before you poll its state, you will have +missed the button press. The recommended solution for this is to use a +mouse button callback, but there is also the `GLFW_STICKY_MOUSE_BUTTONS` +input mode. + +@code +glfwSetInputMode(window, GLFW_STICKY_MOUSE_BUTTONS, 1); +@endcode + +When sticky mouse buttons mode is enabled, the pollable state of a mouse button +will remain `GLFW_PRESS` until the state of that button is polled with @ref +glfwGetMouseButton. Once it has been polled, if a mouse button release event +had been processed in the meantime, the state will reset to `GLFW_RELEASE`, +otherwise it will remain `GLFW_PRESS`. + +The `GLFW_MOUSE_BUTTON_LAST` constant holds the highest value of any +[named button](@ref buttons). + + +@subsection scrolling Scroll input + +If you wish to be notified when the user scrolls, whether with a mouse wheel or +touchpad gesture, set a scroll callback. + +@code +glfwSetScrollCallback(window, scroll_callback); +@endcode + +The callback function receives two-dimensional scroll offsets. + +@code +void scroll_callback(GLFWwindow* window, double xoffset, double yoffset) +{ +} +@endcode + +A normal mouse wheel, being vertical, provides offsets along the Y-axis. + + +@section joystick Joystick input + +The joystick functions expose connected joysticks and controllers, with both +referred to as joysticks. It supports up to sixteen joysticks, ranging from +`GLFW_JOYSTICK_1`, `GLFW_JOYSTICK_2` up to and including `GLFW_JOYSTICK_16` or +`GLFW_JOYSTICK_LAST`. You can test whether a [joystick](@ref joysticks) is +present with @ref glfwJoystickPresent. + +@code +int present = glfwJoystickPresent(GLFW_JOYSTICK_1); +@endcode + +Each joystick has zero or more axes, zero or more buttons, zero or more hats, +a human-readable name, a user pointer and an SDL compatible GUID. + +When GLFW is initialized, detected joysticks are added to to the beginning of +the array. Once a joystick is detected, it keeps its assigned ID until it is +disconnected or the library is terminated, so as joysticks are connected and +disconnected, there may appear gaps in the IDs. + +Joystick axis, button and hat state is updated when polled and does not require +a window to be created or events to be processed. However, if you want joystick +connection and disconnection events reliably delivered to the +[joystick callback](@ref joystick_event) then you must +[process events](@ref events). + +To see all the properties of all connected joysticks in real-time, run the +`joysticks` test program. + + +@subsection joystick_axis Joystick axis states + +The positions of all axes of a joystick are returned by @ref +glfwGetJoystickAxes. See the reference documentation for the lifetime of the +returned array. + +@code +int count; +const float* axes = glfwGetJoystickAxes(GLFW_JOYSTICK_5, &count); +@endcode + +Each element in the returned array is a value between -1.0 and 1.0. + + +@subsection joystick_button Joystick button states + +The states of all buttons of a joystick are returned by @ref +glfwGetJoystickButtons. See the reference documentation for the lifetime of the +returned array. + +@code +int count; +const unsigned char* buttons = glfwGetJoystickButtons(GLFW_JOYSTICK_3, &count); +@endcode + +Each element in the returned array is either `GLFW_PRESS` or `GLFW_RELEASE`. + +For backward compatibility with earlier versions that did not have @ref +glfwGetJoystickHats, the button array by default also includes all hats. See +the reference documentation for @ref glfwGetJoystickButtons for details. + + +@subsection joystick_hat Joystick hat states + +The states of all hats are returned by @ref glfwGetJoystickHats. See the +reference documentation for the lifetime of the returned array. + +@code +int count; +const unsigned char* hats = glfwGetJoystickHats(GLFW_JOYSTICK_7, &count); +@endcode + +Each element in the returned array is one of the following: + +Name | Value +--------------------- | -------------------------------- +`GLFW_HAT_CENTERED` | 0 +`GLFW_HAT_UP` | 1 +`GLFW_HAT_RIGHT` | 2 +`GLFW_HAT_DOWN` | 4 +`GLFW_HAT_LEFT` | 8 +`GLFW_HAT_RIGHT_UP` | `GLFW_HAT_RIGHT` \| `GLFW_HAT_UP` +`GLFW_HAT_RIGHT_DOWN` | `GLFW_HAT_RIGHT` \| `GLFW_HAT_DOWN` +`GLFW_HAT_LEFT_UP` | `GLFW_HAT_LEFT` \| `GLFW_HAT_UP` +`GLFW_HAT_LEFT_DOWN` | `GLFW_HAT_LEFT` \| `GLFW_HAT_DOWN` + +The diagonal directions are bitwise combinations of the primary (up, right, down +and left) directions and you can test for these individually by ANDing it with +the corresponding direction. + +@code +if (hats[2] & GLFW_HAT_RIGHT) +{ + // State of hat 2 could be right-up, right or right-down +} +@endcode + +For backward compatibility with earlier versions that did not have @ref +glfwGetJoystickHats, all hats are by default also included in the button array. +See the reference documentation for @ref glfwGetJoystickButtons for details. + + +@subsection joystick_name Joystick name + +The human-readable, UTF-8 encoded name of a joystick is returned by @ref +glfwGetJoystickName. See the reference documentation for the lifetime of the +returned string. + +@code +const char* name = glfwGetJoystickName(GLFW_JOYSTICK_4); +@endcode + +Joystick names are not guaranteed to be unique. Two joysticks of the same model +and make may have the same name. Only the [joystick token](@ref joysticks) is +guaranteed to be unique, and only until that joystick is disconnected. + + +@subsection joystick_userptr Joystick user pointer + +Each joystick has a user pointer that can be set with @ref +glfwSetJoystickUserPointer and queried with @ref glfwGetJoystickUserPointer. +This can be used for any purpose you need and will not be modified by GLFW. The +value will be kept until the joystick is disconnected or until the library is +terminated. + +The initial value of the pointer is `NULL`. + + +@subsection joystick_event Joystick configuration changes + +If you wish to be notified when a joystick is connected or disconnected, set +a joystick callback. + +@code +glfwSetJoystickCallback(joystick_callback); +@endcode + +The callback function receives the ID of the joystick that has been connected +and disconnected and the event that occurred. + +@code +void joystick_callback(int jid, int event) +{ + if (event == GLFW_CONNECTED) + { + // The joystick was connected + } + else if (event == GLFW_DISCONNECTED) + { + // The joystick was disconnected + } +} +@endcode + +For joystick connection and disconnection events to be delivered on all +platforms, you need to call one of the [event processing](@ref events) +functions. Joystick disconnection may also be detected and the callback +called by joystick functions. The function will then return whatever it +returns for a disconnected joystick. + +Only @ref glfwGetJoystickName and @ref glfwGetJoystickUserPointer will return +useful values for a disconnected joystick and only before the monitor callback +returns. + + +@subsection gamepad Gamepad input + +The joystick functions provide unlabeled axes, buttons and hats, with no +indication of where they are located on the device. Their order may also vary +between platforms even with the same device. + +To solve this problem the SDL community crowdsourced the +[SDL_GameControllerDB](https://github.com/gabomdq/SDL_GameControllerDB) project, +a database of mappings from many different devices to an Xbox-like gamepad. + +GLFW supports this mapping format and contains a copy of the mappings +available at the time of release. See @ref gamepad_mapping for how to update +this at runtime.

Newer ones can be added at runtime with @ref +glfwUpdateGamepadMappings. + +@code +const char* mappings = load_file_contents("gamecontrollerdb.txt"); + +glfwUpdateGamepadMappings(mappings); +@endcode + +This function supports everything from single lines up to and including the +unmodified contents of the whole `gamecontrollerdb.txt` file. + +Below is a description of the mapping format. Please keep in mind that __this +description is not authoritative__. The format is defined by the SDL and +SDL_GameControllerDB projects and their documentation and code takes precedence. + +Each mapping is a single line of comma-separated values describing the GUID, +name and layout of the gamepad. Lines that do not begin with a hexadecimal +digit are ignored. + +The first value is always the gamepad GUID, a 32 character long hexadecimal +string that typically identifies its make, model, revision and the type of +connection to the computer. When this information is not available, the GUID is +generated using the gamepad name. GLFW uses the SDL 2.0.5+ GUID format but can +convert from the older formats. + +The second value is always the human-readable name of the gamepad. + +All subsequent values are in the form `:` and describe the layout +of the mapping. These fields may not all be present and may occur in any order. + +The button fields are `a`, `b`, `c`, `d`, `back`, `start`, `guide`, `dpup`, +`dpright`, `dpdown`, `dpleft`, `leftshoulder`, `rightshoulder`, `leftstick` and +`rightstick`. + +The axis fields are `leftx`, `lefty`, `rightx`, `righty`, `lefttrigger` and +`righttrigger`. + +The value of an axis or button field can be a joystick button, a joystick axis, +a hat bitmask or empty. Joystick buttons are specified as `bN`, for example +`b2` for the third button. Joystick axes are specified as `aN`, for example +`a7` for the eighth button. Joystick hat bit masks are specified as `hN.N`, for +example `h0.8` for left on the first hat. More than one bit may be set in the +mask. + +Before an axis there may be a `+` or `-` range modifier, for example `+a3` for +the positive half of the fourth axis. This restricts input to only the positive +or negative halves of the joystick axis. After an axis or half-axis there may +be the `~` inversion modifier, for example `a2~` or `-a7~`. This negates the +values of the gamepad axis. + +The hat bit mask match the [hat states](@ref hat_state) in the joystick +functions. + +There is also the special `platform` field that specifies which platform the +mapping is valid for. Possible values are `Windows`, `Mac OS X` and `Linux`. + +Below is an example of what a gamepad mapping might look like. It is the +one built into GLFW for Xbox controllers accessed via the XInput API on Windows. +This example has been broken into several lines to fit on the page, but real +gamepad mappings must be a single line. + +@code{.unparsed} +78696e70757401000000000000000000,XInput Gamepad (GLFW),platform:Windows,a:b0, +b:b1,x:b2,y:b3,leftshoulder:b4,rightshoulder:b5,back:b6,start:b7,leftstick:b8, +rightstick:b9,leftx:a0,lefty:a1,rightx:a2,righty:a3,lefttrigger:a4, +righttrigger:a5,dpup:h0.1,dpright:h0.2,dpdown:h0.4,dpleft:h0.8, +@endcode + +@note GLFW does not yet support the output range and modifiers `+` and `-` that +were recently added to SDL.

This is done with @ref glfwTerminate. + +@code +glfwTerminate(); +@endcode + +This will destroy any remaining window, monitor and cursor objects, restore any +modified gamma ramps, re-enable the screensaver if it had been disabled and free +any other resources allocated by GLFW. + +Once the library is terminated, it is as if it had never been initialized and +you will need to initialize it again before being able to use GLFW. If the +library was not initialized or had already been terminated, it return +immediately. + + +@section error_handling Error handling + +Some GLFW functions have return values that indicate an error, but this is often +not very helpful when trying to figure out what happened or why it occurred. +Other functions have no return value reserved for errors, so error notification +needs a separate channel. Finally, far from all GLFW functions have return +values. + +The last [error code](@ref errors) for the calling thread can be queried at any +time with @ref glfwGetError. + +@code +int code = glfwGetError(NULL); + +if (code != GLFW_NO_ERROR) + handle_error(code); +@endcode + +If no error has occurred since the last call, @ref GLFW_NO_ERROR (zero) is +returned. The error is cleared before the function returns. + +The error code indicates the general category of the error. Some error codes, +such as @ref GLFW_NOT_INITIALIZED has only a single meaning, whereas others like +@ref GLFW_PLATFORM_ERROR are used for many different errors. + +GLFW often has more information about an error than its general category. You +can retrieve a UTF-8 encoded human-readable description along with the error +code. If no error has occurred since the last call, the description is set to +`NULL`. + +@code +const char* description; +int code = glfwGetError(&description); + +if (description) + display_error_message(code, description); +@endcode + +The retrieved description string is only valid until the next error occurs. +This means you must make a copy of it if you want to keep it. + +You can also set an error callback, which will be called each time an error +occurs. It is set with @ref glfwSetErrorCallback. + +@code +glfwSetErrorCallback(error_callback); +@endcode + +The error callback receives the same error code and human-readable description +returned by @ref glfwGetError. + +@code +void error_callback(int code, const char* description) +{ + display_error_message(code, description); +} +@endcode + +The error callback is called after the error is stored, so calling @ref +glfwGetError from within the error callback returns the same values as the +callback argument. + +The description string passed to the callback is only valid until the error +callback returns. This means you must make a copy of it if you want to keep it. + +__Reported errors are never fatal.__ As long as GLFW was successfully +initialized, it will remain initialized and in a safe state until terminated +regardless of how many errors occur. If an error occurs during initialization +that causes @ref glfwInit to fail, any part of the library that was initialized +will be safely terminated. + +Do not rely on a currently invalid call to generate a specific error, as in the +future that same call may generate a different error or become valid. + + +@section coordinate_systems Coordinate systems + +GLFW has two primary coordinate systems: the _virtual screen_ and the window +_client area_ or _content area_. Both use the same unit: _virtual screen +coordinates_, or just _screen coordinates_, which don't necessarily correspond +to pixels. + + + +Both the virtual screen and the client area coordinate systems have the X-axis +pointing to the right and the Y-axis pointing down. + +Window and monitor positions are specified as the position of the upper-left +corners of their content areas relative to the virtual screen, while cursor +positions are specified relative to a window's client area. + +Because the origin of the window's client area coordinate system is also the +point from which the window position is specified, you can translate client area +coordinates to the virtual screen by adding the window position. The window +frame, when present, extends out from the client area but does not affect the +window position. + +Almost all positions and sizes in GLFW are measured in screen coordinates +relative to one of the two origins above. This includes cursor positions, +window positions and sizes, window frame sizes, monitor positions and video mode +resolutions. + +Two exceptions are the [monitor physical size](@ref monitor_size), which is +measured in millimetres, and [framebuffer size](@ref window_fbsize), which is +measured in pixels. + +Pixels and screen coordinates may map 1:1 on your machine, but they won't on +every other machine, for example on a Mac with a Retina display. The ratio +between screen coordinates and pixels may also change at run-time depending on +which monitor the window is currently considered to be on. + + +@section guarantees_limitations Guarantees and limitations + +This section describes the conditions under which GLFW can be expected to +function, barring bugs in the operating system or drivers. Use of GLFW outside +of these limits may work on some platforms, or on some machines, or some of the +time, or on some versions of GLFW, but it may break at any time and this will +not be considered a bug. + + +@subsection lifetime Pointer lifetimes + +GLFW will never free any pointer you provide to it and you must never free any +pointer it provides to you. + +Many GLFW functions return pointers to dynamically allocated structures, strings +or arrays, and some callbacks are provided with strings or arrays. These are +always managed by GLFW and should never be freed by the application. The +lifetime of these pointers is documented for each GLFW function and callback. +If you need to keep this data, you must copy it before its lifetime expires. + +Many GLFW functions accept pointers to structures or strings allocated by the +application. These are never freed by GLFW and are always the responsibility of +the application. If GLFW needs to keep the data in these structures or strings, +it is copied before the function returns. + +Pointer lifetimes are guaranteed not to be shortened in future minor or patch +releases. + + +@subsection reentrancy Reentrancy + +GLFW event processing and object destruction are not reentrant. This means that +the following functions must not be called from any callback function: + + - @ref glfwDestroyWindow + - @ref glfwDestroyCursor + - @ref glfwPollEvents + - @ref glfwWaitEvents + - @ref glfwWaitEventsTimeout + - @ref glfwTerminate + +These functions may be made reentrant in future minor or patch releases, but +functions not on this list will not be made non-reentrant. + + +@subsection thread_safety Thread safety + +Most GLFW functions must only be called from the main thread (the thread that +calls main), but some may be called from any thread once the library has been +initialized. Before initialization the whole library is thread-unsafe. + +The reference documentation for every GLFW function states whether it is limited +to the main thread. + +Initialization, termination, event processing and the creation and +destruction of windows, cursors and OpenGL and OpenGL ES contexts are all +restricted to the main thread due to limitations of one or several platforms. + +Because event processing must be performed on the main thread, all callbacks +except for the error callback will only be called on that thread. The error +callback may be called on any thread, as any GLFW function may generate errors. + +The error code and description may be queried from any thread. + + - @ref glfwGetError + +Empty events may be posted from any thread. + + - @ref glfwPostEmptyEvent + +The window user pointer and close flag may be read and written from any thread, +but this is not synchronized by GLFW. + + - @ref glfwGetWindowUserPointer + - @ref glfwSetWindowUserPointer + - @ref glfwWindowShouldClose + - @ref glfwSetWindowShouldClose + +These functions for working with OpenGL and OpenGL ES contexts may be called +from any thread, but the window object is not synchronized by GLFW. + + - @ref glfwMakeContextCurrent + - @ref glfwGetCurrentContext + - @ref glfwSwapBuffers + - @ref glfwSwapInterval + - @ref glfwExtensionSupported + - @ref glfwGetProcAddress + +The raw timer functions may be called from any thread. + + - @ref glfwGetTimerFrequency + - @ref glfwGetTimerValue + +The regular timer may be used from any thread, but reading and writing the timer +offset is not synchronized by GLFW. + + - @ref glfwGetTime + - @ref glfwSetTime + +Library version information may be queried from any thread. + + - @ref glfwGetVersion + - @ref glfwGetVersionString + +All Vulkan related functions may be called from any thread. + + - @ref glfwVulkanSupported + - @ref glfwGetRequiredInstanceExtensions + - @ref glfwGetInstanceProcAddress + - @ref glfwGetPhysicalDevicePresentationSupport + - @ref glfwCreateWindowSurface + +GLFW uses synchronization objects internally only to manage the per-thread +context and error states. Additional synchronization is left to the +application. + +Functions that may currently be called from any thread will always remain so, +but functions that are currently limited to the main thread may be updated to +allow calls from any thread in future releases. + + +@subsection compatibility Version compatibility + +GLFW uses [Semantic Versioning](https://semver.org/). This guarantees source +and binary backward compatibility with earlier minor versions of the API. This +means that you can drop in a newer version of the library and existing programs +will continue to compile and existing binaries will continue to run. + +Once a function or constant has been added, the signature of that function or +value of that constant will remain unchanged until the next major version of +GLFW. No compatibility of any kind is guaranteed between major versions. + +Undocumented behavior, i.e. behavior that is not described in the documentation, +may change at any time until it is documented. + +If the reference documentation and the implementation differ, the reference +documentation will almost always take precedence and the implementation will be +fixed in the next release. The reference documentation will also take +precedence over anything stated in a guide. + + +@subsection event_order Event order + +The order of arrival of related events is not guaranteed to be consistent +across platforms. The exception is synthetic key and mouse button release +events, which are always delivered after the window defocus event. + + +@section intro_version Version management + +GLFW provides mechanisms for identifying what version of GLFW your application +was compiled against as well as what version it is currently running against. +If you are loading GLFW dynamically (not just linking dynamically), you can use +this to verify that the library binary is compatible with your application. + + +@subsection intro_version_compile Compile-time version + +The compile-time version of GLFW is provided by the GLFW header with the +`GLFW_VERSION_MAJOR`, `GLFW_VERSION_MINOR` and `GLFW_VERSION_REVISION` macros. + +@code +printf("Compiled against GLFW %i.%i.%i\n", + GLFW_VERSION_MAJOR, + GLFW_VERSION_MINOR, + GLFW_VERSION_REVISION); +@endcode + + +@subsection intro_version_runtime Run-time version + +The run-time version can be retrieved with @ref glfwGetVersion, a function that +may be called regardless of whether GLFW is initialized. + +@code +int major, minor, revision; +glfwGetVersion(&major, &minor, &revision); + +printf("Running against GLFW %i.%i.%i\n", major, minor, revision); +@endcode + + +@subsection intro_version_string Version string + +GLFW 3 also provides a compile-time generated version string that describes the +version, platform, compiler and any platform-specific compile-time options. +This is primarily intended for submitting bug reports, to allow developers to +see which code paths are enabled in a binary. + +The version string is returned by @ref glfwGetVersionString, a function that may +be called regardless of whether GLFW is initialized. + +__Do not use the version string__ to parse the GLFW library version.

There are +better threading libraries available and native threading support is available +in both [C++11](http://en.cppreference.com/w/cpp/thread) and +[C11](http://en.cppreference.com/w/c/thread), both of which are gaining +traction. + +If you wish to use the C++11 or C11 facilities but your compiler doesn't yet +support them, see the +[TinyThread++](https://gitorious.org/tinythread/tinythreadpp) and +[TinyCThread](https://github.com/tinycthread/tinycthread) projects created by +the original author of GLFW.

They only supported +the Targa image format, making them mostly useful for beginner level examples. +To become of sufficiently high quality to warrant keeping them in GLFW 3, they +would need not only to support other formats, but also modern extensions to +OpenGL texturing. This would either add a number of external +dependencies (libjpeg, libpng, etc.), or force GLFW to ship with inline versions +of these libraries. + +As there already are libraries doing this, it is unnecessary both to duplicate +the work and to tie the duplicate to GLFW. The resulting library would also be +platform-independent, as both OpenGL and stdio are available wherever GLFW is. + +@par Removed functions +`glfwReadImage`, `glfwReadMemoryImage`, `glfwFreeImage`, `glfwLoadTexture2D`, +`glfwLoadMemoryTexture2D` and `glfwLoadTextureImage2D`. + + +@subsection moving_stdcall Removal of GLFWCALL macro + +The `GLFWCALL` macro, which made callback functions use +[__stdcall](http://msdn.microsoft.com/en-us/library/zxk0tw93.aspx) on Windows, +has been removed. GLFW is written in C, not Pascal. Removing this macro means +there's one less thing for application programmers to remember, i.e. the +requirement to mark all callback functions with `GLFWCALL`.

Unlike +buffer swap, which acts on a single window, the event processing functions act +on all windows at once. + +@par Old basic main loop +@code +while (...) +{ + // Process input + // Render output + glfwSwapBuffers(); +} +@endcode + +@par New basic main loop +@code +while (...) +{ + // Process input + // Render output + glfwSwapBuffers(window); + glfwPollEvents(); +} +@endcode + + +@subsection moving_context Explicit context management + +Each GLFW 3 window has its own OpenGL context and only you, the application +programmer, can know which context should be current on which thread at any +given time. Therefore, GLFW 3 leaves that decision to you. + +This means that you need to call @ref glfwMakeContextCurrent after creating +a window before you can call any OpenGL functions. + + +@subsection moving_hidpi Separation of window and framebuffer sizes + +Window positions and sizes now use screen coordinates, which may not be the same +as pixels on machines with high-DPI monitors. This is important as OpenGL uses +pixels, not screen coordinates. For example, the rectangle specified with +`glViewport` needs to use pixels. Therefore, framebuffer size functions have +been added. You can retrieve the size of the framebuffer of a window with @ref +glfwGetFramebufferSize function. A framebuffer size callback has also been +added, which can be set with @ref glfwSetFramebufferSizeCallback. + +@par Old basic viewport setup +@code +glfwGetWindowSize(&width, &height); +glViewport(0, 0, width, height); +@endcode + +@par New basic viewport setup +@code +glfwGetFramebufferSize(window, &width, &height); +glViewport(0, 0, width, height); +@endcode + + +@subsection moving_window_close Window closing changes + +The `GLFW_OPENED` window parameter has been removed. As long as the window has +not been destroyed, whether through @ref glfwDestroyWindow or @ref +glfwTerminate, the window is "open". + +A user attempting to close a window is now just an event like any other. Unlike +GLFW 2, windows and contexts created with GLFW 3 will never be destroyed unless +you choose them to be. Each window now has a close flag that is set to +`GLFW_TRUE` when the user attempts to close that window. By default, nothing else +happens and the window stays visible. It is then up to you to either destroy +the window, take some other action or ignore the request. + +You can query the close flag at any time with @ref glfwWindowShouldClose and set +it at any time with @ref glfwSetWindowShouldClose. + +@par Old basic main loop +@code +while (glfwGetWindowParam(GLFW_OPENED)) +{ + ... +} +@endcode + +@par New basic main loop +@code +while (!glfwWindowShouldClose(window)) +{ + ... +} +@endcode + +The close callback no longer returns a value. Instead, it is called after the +close flag has been set so it can override its value, if it chooses to, before +event processing completes.

The @ref glfwGetVideoModes function +now returns all available modes for a specific monitor instead of requiring you +to guess how large an array you need. The `glfwGetDesktopMode` function, which +had poorly defined behavior, has been replaced by @ref glfwGetVideoMode, which +returns the current mode of a monitor. + + +@subsection moving_char_up Removal of character actions + +The action parameter of the [character callback](@ref GLFWcharfun) has been +removed. This was an artefact of the origin of GLFW, i.e. being developed in +English by a Swede. However, many keyboard layouts require more than one key to +produce characters with diacritical marks. Even the Swedish keyboard layout +requires this for uncommon cases like ü. + +@par Old syntax +@code +void GLFWCALL character_callback(int character, int action); +@endcode + +@par New syntax +@code +void character_callback(GLFWwindow* window, int character); +@endcode + + +@subsection moving_cursorpos Cursor position changes + +The `glfwGetMousePos` function has been renamed to @ref glfwGetCursorPos, +`glfwSetMousePos` to @ref glfwSetCursorPos and `glfwSetMousePosCallback` to @ref +glfwSetCursorPosCallback. + +The cursor position is now `double` instead of `int`, both for the direct +functions and for the callback. Some platforms can provide sub-pixel cursor +movement and this data is now passed on to the application where available. On +platforms where this is not provided, the decimal part is zero. + +GLFW 3 only allows you to position the cursor within a window using @ref +glfwSetCursorPos (formerly `glfwSetMousePos`) when that window is active. +Unless the window is active, the function fails silently. + + +@subsection moving_wheel Wheel position replaced by scroll offsets + +The `glfwGetMouseWheel` function has been removed. Scrolling is the input of +offsets and has no absolute position. The mouse wheel callback has been +replaced by a [scroll callback](@ref GLFWscrollfun) that receives +two-dimensional floating point scroll offsets. This allows you to receive +precise scroll data from for example modern touchpads. + +@par Old syntax +@code +void GLFWCALL mouse_wheel_callback(int position); +@endcode + +@par New syntax +@code +void scroll_callback(GLFWwindow* window, double xoffset, double yoffset); +@endcode + +@par Removed functions +`glfwGetMouseWheel` + + +@subsection moving_repeat Key repeat action + +The `GLFW_KEY_REPEAT` enable has been removed and key repeat is always enabled +for both keys and characters. A new key action, `GLFW_REPEAT`, has been added +to allow the [key callback](@ref GLFWkeyfun) to distinguish an initial key press +from a repeat. Note that @ref glfwGetKey still returns only `GLFW_PRESS` or +`GLFW_RELEASE`. + + +@subsection moving_keys Physical key input + +GLFW 3 key tokens map to physical keys, unlike in GLFW 2 where they mapped to +the values generated by the current keyboard layout. The tokens are named +according to the values they would have using the standard US layout, but this +is only a convenience, as most programmers are assumed to know that layout. +This means that (for example) `GLFW_KEY_LEFT_BRACKET` is always a single key and +is the same key in the same place regardless of what keyboard layouts the users +of your program has. + +The key input facility was never meant for text input, although using it that +way worked slightly better in GLFW 2. If you were using it to input text, you +should be using the character callback instead, on both GLFW 2 and 3. This will +give you the characters being input, as opposed to the keys being pressed. + +GLFW 3 has key tokens for all keys on a standard 105 key keyboard, so instead of +having to remember whether to check for `'a'` or `'A'`, you now check for +`GLFW_KEY_A`. + + +@subsection moving_joystick Joystick function changes + +The `glfwGetJoystickPos` function has been renamed to @ref glfwGetJoystickAxes. + +The `glfwGetJoystickParam` function and the `GLFW_PRESENT`, `GLFW_AXES` and +`GLFW_BUTTONS` tokens have been replaced by the @ref glfwJoystickPresent +function as well as axis and button counts returned by the @ref +glfwGetJoystickAxes and @ref glfwGetJoystickButtons functions. + + +@subsection moving_mbcs Win32 MBCS support + +The Win32 port of GLFW 3 will not compile in +[MBCS mode](http://msdn.microsoft.com/en-us/library/5z097dxa.aspx). +However, because the use of the Unicode version of the Win32 API doesn't affect +the process as a whole, but only those windows created using it, it's perfectly +possible to call MBCS functions from other parts of the same application. +Therefore, even if an application using GLFW has MBCS mode code, there's no need +for GLFW itself to support it. + + +@subsection moving_windows Support for versions of Windows older than XP + +All explicit support for version of Windows older than XP has been removed. +There is no code that actively prevents GLFW 3 from running on these earlier +versions, but it uses Win32 functions that those versions lack. + +Windows XP was released in 2001, and by now (January 2015) it has not only +replaced almost all earlier versions of Windows, but is itself rapidly being +replaced by Windows 7 and 8. The MSDN library doesn't even provide +documentation for version older than Windows 2000, making it difficult to +maintain compatibility with these versions even if it was deemed worth the +effort. + +The Win32 API has also not stood still, and GLFW 3 uses many functions only +present on Windows XP or later. Even supporting an OS as new as XP (new +from the perspective of GLFW 2, which still supports Windows 95) requires +runtime checking for a number of functions that are present only on modern +version of Windows. + + +@subsection moving_syskeys Capture of system-wide hotkeys + +The ability to disable and capture system-wide hotkeys like Alt+Tab has been +removed. Modern applications, whether they're games, scientific visualisations +or something else, are nowadays expected to be good desktop citizens and allow +these hotkeys to function even when running in full screen mode. + + +@subsection moving_terminate Automatic termination + +GLFW 3 does not register @ref glfwTerminate with `atexit` at initialization, +because `exit` calls registered functions from the calling thread and while it +is permitted to call `exit` from any thread, @ref glfwTerminate must only be +called from the main thread. + +To release all resources allocated by GLFW, you should call @ref glfwTerminate +yourself, from the main thread, before the program terminates. Note that this +destroys all windows not already destroyed with @ref glfwDestroyWindow, +invalidating any window handles you may still have. + + +@subsection moving_glu GLU header inclusion + +GLFW 3 does not by default include the GLU header and GLU itself has been +deprecated by [Khronos](https://en.wikipedia.org/wiki/Khronos_Group). __New +projects should not use GLU__, but if you need it for legacy code that +has been moved to GLFW 3, you can request that the GLFW header includes it by +defining @ref GLFW_INCLUDE_GLU before the inclusion of the GLFW header. + +@par Old syntax +@code +#include +@endcode + +@par New syntax +@code +#define GLFW_INCLUDE_GLU +#include +@endcode + +There are many libraries that offer replacements for the functionality offered +by GLU.

There is also @ref +glfwSetGamma, which generates a ramp from a gamma value and then sets it. + + +@subsection news_30_gles OpenGL ES support + +GLFW now supports the creation of OpenGL ES contexts, by setting the +[GLFW_CLIENT_API](@ref GLFW_CLIENT_API_hint) hint to `GLFW_OPENGL_ES_API`, where +creation of such contexts are supported. Note that GLFW _does not implement_ +OpenGL ES, so your driver must provide support in a way usable by GLFW. Modern +Nvidia and Intel drivers support creation of OpenGL ES context using the GLX and +WGL APIs, while AMD provides an EGL implementation instead. + + +@subsection news_30_egl (Experimental) EGL support + +GLFW now has an experimental EGL context creation back end that can be selected +through CMake options. + + +@subsection news_30_hidpi High-DPI support + +GLFW now supports high-DPI monitors on both Windows and macOS, giving windows +full resolution framebuffers where other UI elements are scaled up. To achieve +this, @ref glfwGetFramebufferSize and @ref glfwSetFramebufferSizeCallback have +been added. These work with pixels, while the rest of the GLFW API works with +screen coordinates. This is important as OpenGL uses pixels, not screen +coordinates. + + +@subsection news_30_error Error callback + +GLFW now has an error callback, which can provide your application with much +more detailed diagnostics than was previously possible. The callback is passed +an error code and a description string. + + +@subsection news_30_wndptr Per-window user pointer + +Each window now has a user-defined pointer, retrieved with @ref +glfwGetWindowUserPointer and set with @ref glfwSetWindowUserPointer, to make it +easier to integrate GLFW into C++ code. + + +@subsection news_30_iconifyfun Window iconification callback + +Each window now has a callback for iconification and restoration events, +which is set with @ref glfwSetWindowIconifyCallback. + + +@subsection news_30_wndposfun Window position callback + +Each window now has a callback for position events, which is set with @ref +glfwSetWindowPosCallback. + + +@subsection news_30_wndpos Window position query + +The position of a window can now be retrieved using @ref glfwGetWindowPos. + + +@subsection news_30_focusfun Window focus callback + +Each windows now has a callback for focus events, which is set with @ref +glfwSetWindowFocusCallback. + + +@subsection news_30_enterleave Cursor enter/leave callback + +Each window now has a callback for when the mouse cursor enters or leaves its +client area, which is set with @ref glfwSetCursorEnterCallback. + + +@subsection news_30_wndtitle Initial window title + +The title of a window is now specified at creation time, as one of the arguments +to @ref glfwCreateWindow. + + +@subsection news_30_hidden Hidden windows + +Windows can now be hidden with @ref glfwHideWindow, shown using @ref +glfwShowWindow and created initially hidden with the @ref GLFW_VISIBLE window +hint and attribute.

The most extreme case is Windows, which only +exposes OpenGL 1.2.

This example uses +[glad](https://github.com/Dav1dde/glad), but the same rule applies to all such +libraries. + +@code +#include +#include +@endcode + + +@subsection quick_init_term Initializing and terminating GLFW + +Before you can use most GLFW functions, the library must be initialized. On +successful initialization, `GLFW_TRUE` is returned. If an error occurred, +`GLFW_FALSE` is returned. + +@code +if (!glfwInit()) +{ + // Initialization failed +} +@endcode + +Note that `GLFW_TRUE` and `GLFW_FALSE` are and will always be one and zero. + +When you are done using GLFW, typically just before the application exits, you +need to terminate GLFW. + +@code +glfwTerminate(); +@endcode + +This destroys any remaining windows and releases any other resources allocated by +GLFW. After this call, you must initialize GLFW again before using any GLFW +functions that require it. + + +@subsection quick_capture_error Setting an error callback + +Most events are reported through callbacks, whether it's a key being pressed, +a GLFW window being moved, or an error occurring. Callbacks are C functions (or +C++ static methods) that are called by GLFW with arguments describing the event. + +In case a GLFW function fails, an error is reported to the GLFW error callback. +You can receive these reports with an error callback. This function must have +the signature below but may do anything permitted in other callbacks. + +@code +void error_callback(int error, const char* description) +{ + fprintf(stderr, "Error: %s\n", description); +} +@endcode + +Callback functions must be set, so GLFW knows to call them. The function to set +the error callback is one of the few GLFW functions that may be called before +initialization, which lets you be notified of errors both during and after +initialization. + +@code +glfwSetErrorCallback(error_callback); +@endcode + + +@subsection quick_create_window Creating a window and context + +The window and its OpenGL context are created with a single call to @ref +glfwCreateWindow, which returns a handle to the created combined window and +context object + +@code +GLFWwindow* window = glfwCreateWindow(640, 480, "My Title", NULL, NULL); +if (!window) +{ + // Window or OpenGL context creation failed +} +@endcode + +This creates a 640 by 480 windowed mode window with an OpenGL context. If +window or OpenGL context creation fails, `NULL` will be returned. You should +always check the return value. While window creation rarely fails, context +creation depends on properly installed drivers and may fail even on machines +with the necessary hardware. + +By default, the OpenGL context GLFW creates may have any version. You can +require a minimum OpenGL version by setting the `GLFW_CONTEXT_VERSION_MAJOR` and +`GLFW_CONTEXT_VERSION_MINOR` hints _before_ creation. If the required minimum +version is not supported on the machine, context (and window) creation fails. + +@code +glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 2); +glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 0); +GLFWwindow* window = glfwCreateWindow(640, 480, "My Title", NULL, NULL); +if (!window) +{ + // Window or context creation failed +} +@endcode + +The window handle is passed to all window related functions and is provided to +along to all window related callbacks, so they can tell which window received +the event. + +When a window and context is no longer needed, destroy it. + +@code +glfwDestroyWindow(window); +@endcode + +Once this function is called, no more events will be delivered for that window +and its handle becomes invalid. + + +@subsection quick_context_current Making the OpenGL context current + +Before you can use the OpenGL API, you must have a current OpenGL context. + +@code +glfwMakeContextCurrent(window); +@endcode + +The context will remain current until you make another context current or until +the window owning the current context is destroyed. + +If you are using an [extension loader library](@ref context_glext_auto) to +access modern OpenGL then this is when to initialize it, as the loader needs +a current context to load from. This example uses +[glad](https://github.com/Dav1dde/glad), but the same rule applies to all such +libraries. + +@code +gladLoadGLLoader((GLADloadproc) glfwGetProcAddress); +@endcode + + +@subsection quick_window_close Checking the window close flag + +Each window has a flag indicating whether the window should be closed. + +When the user attempts to close the window, either by pressing the close widget +in the title bar or using a key combination like Alt+F4, this flag is set to 1. +Note that __the window isn't actually closed__, so you are expected to monitor +this flag and either destroy the window or give some kind of feedback to the +user. + +@code +while (!glfwWindowShouldClose(window)) +{ + // Keep running +} +@endcode + +You can be notified when the user is attempting to close the window by setting +a close callback with @ref glfwSetWindowCloseCallback. The callback will be +called immediately after the close flag has been set. + +You can also set it yourself with @ref glfwSetWindowShouldClose. This can be +useful if you want to interpret other kinds of input as closing the window, like +for example pressing the _Escape_ key. + + +@subsection quick_key_input Receiving input events + +Each window has a large number of callbacks that can be set to receive all the +various kinds of events. To receive key press and release events, create a key +callback function. + +@code +static void key_callback(GLFWwindow* window, int key, int scancode, int action, int mods) +{ + if (key == GLFW_KEY_ESCAPE && action == GLFW_PRESS) + glfwSetWindowShouldClose(window, GLFW_TRUE); +} +@endcode + +The key callback, like other window related callbacks, are set per-window. + +@code +glfwSetKeyCallback(window, key_callback); +@endcode + +In order for event callbacks to be called when events occur, you need to process +events as described below. + + +@subsection quick_render Rendering with OpenGL + +Once you have a current OpenGL context, you can use OpenGL normally. In this +tutorial, a multi-colored rotating triangle will be rendered. The framebuffer +size needs to be retrieved for `glViewport`. + +@code +int width, height; +glfwGetFramebufferSize(window, &width, &height); +glViewport(0, 0, width, height); +@endcode + +You can also set a framebuffer size callback using @ref +glfwSetFramebufferSizeCallback and be notified when the size changes. + +Actual rendering with OpenGL is outside the scope of this tutorial, but there +are [many](https://open.gl/) [excellent](https://learnopengl.com/) +[tutorial](http://openglbook.com/) [sites](http://ogldev.atspace.co.uk/) that +teach modern OpenGL. Some of them use GLFW to create the context and window +while others use GLUT or SDL, but remember that OpenGL itself always works the +same. + + +@subsection quick_timer Reading the timer + +To create smooth animation, a time source is needed. GLFW provides a timer that +returns the number of seconds since initialization. The time source used is the +most accurate on each platform and generally has micro- or nanosecond +resolution. + +@code +double time = glfwGetTime(); +@endcode + + +@subsection quick_swap_buffers Swapping buffers + +GLFW windows by default use double buffering. That means that each window has +two rendering buffers; a front buffer and a back buffer. The front buffer is +the one being displayed and the back buffer the one you render to. + +When the entire frame has been rendered, the buffers need to be swapped with one +another, so the back buffer becomes the front buffer and vice versa. + +@code +glfwSwapBuffers(window); +@endcode + +The swap interval indicates how many frames to wait until swapping the buffers, +commonly known as _vsync_. By default, the swap interval is zero, meaning +buffer swapping will occur immediately. On fast machines, many of those frames +will never be seen, as the screen is still only updated typically 60-75 times +per second, so this wastes a lot of CPU and GPU cycles. + +Also, because the buffers will be swapped in the middle the screen update, +leading to [screen tearing](https://en.wikipedia.org/wiki/Screen_tearing). + +For these reasons, applications will typically want to set the swap interval to +one. It can be set to higher values, but this is usually not recommended, +because of the input latency it leads to. + +@code +glfwSwapInterval(1); +@endcode + +This function acts on the current context and will fail unless a context is +current. + + +@subsection quick_process_events Processing events + +GLFW needs to communicate regularly with the window system both in order to +receive events and to show that the application hasn't locked up. Event +processing must be done regularly while you have visible windows and is normally +done each frame after buffer swapping. + +There are two methods for processing pending events; polling and waiting. This +example will use event polling, which processes only those events that have +already been received and then returns immediately. + +@code +glfwPollEvents(); +@endcode + +This is the best choice when rendering continually, like most games do. If +instead you only need to update your rendering once you have received new input, +@ref glfwWaitEvents is a better choice. It waits until at least one event has +been received, putting the thread to sleep in the meantime, and then processes +all received events. This saves a great deal of CPU cycles and is useful for, +for example, many kinds of editing tools. + + +@section quick_example Putting it together + +Now that you know how to initialize GLFW, create a window and poll for +keyboard input, it's possible to create a simple program. + +This program creates a 640 by 480 windowed mode window and starts a loop that +clears the screen, renders a triangle and processes events until the user either +presses _Escape_ or closes the window. + +@snippet simple.c code + +The program above can be found in the +[source package](http://www.glfw.org/download.html) as `examples/simple.c` +and is compiled along with all other examples when you build GLFW. If you +built GLFW from the source package then already have this as `simple.exe` on +Windows, `simple` on Linux or `simple.app` on macOS. + +This tutorial used only a few of the many functions GLFW provides.

You can get the +handle for this monitor with @ref glfwGetWindowMonitor. + +@code +GLFWmonitor* monitor = glfwGetWindowMonitor(window); +@endcode + +This monitor handle is one of those returned by @ref glfwGetMonitors. + +For windowed mode windows, this function returns `NULL`. This is how to tell +full screen windows from windowed mode windows. + +You can move windows between monitors or between full screen and windowed mode +with @ref glfwSetWindowMonitor.

This +can be useful if you need to set up your window further before showing it, for +example moving it to a specific location. + + +@subsection window_focus Window input focus + +Windows can be given input focus and brought to the front with @ref +glfwFocusWindow. + +@code +glfwFocusWindow(window); +@endcode + +Keep in mind that it can be very disruptive to the user when a window is forced +to the top.

A single window may not use both methods. The +results of doing this are undefined. + +Both methods require the platform to support it and not every version of every +platform GLFW supports does this, so there are mechanisms to check whether the +window really is transparent. + +Window framebuffers can be made transparent on a per-pixel per-frame basis with +the [GLFW_TRANSPARENT_FRAMEBUFFER](@ref GLFW_TRANSPARENT_FRAMEBUFFER_hint) +window hint. + +@code +glfwWindowHint(GLFW_TRANSPARENT_FRAMEBUFFER, GLFW_TRUE); +@endcode + +If supported by the system, the window content area will be composited with the +background using the framebuffer per-pixel alpha channel. This requires desktop +compositing to be enabled on the system. It does not affect window decorations. + +You can check whether the window framebuffer was successfully made transparent +with the +[GLFW_TRANSPARENT_FRAMEBUFFER](@ref GLFW_TRANSPARENT_FRAMEBUFFER_attrib) +window attribute. + +@code +if (glfwGetWindowAttrib(window, GLFW_TRANSPARENT_FRAMEBUFFER)) +{ + // window framebuffer is currently transparent +} +@endcode + +GLFW comes with an example that enabled framebuffer transparency called `gears`. + +The opacity of the whole window, including any decorations, can be set with @ref +glfwSetWindowOpacity. + +@code +glfwSetWindowOpacity(window, 0.5f); +@endcode + +The opacity (or alpha) value is a positive finite number between zero and one, +where 0 (zero) is fully transparent and 1 (one) is fully opaque. The initial +opacity value for newly created windows is 1. + +The current opacity of a window can be queried with @ref glfwGetWindowOpacity. + +@code +float opacity = glfwGetWindowOpacity(window); +@endcode + +If the system does not support whole window transparency, this function always +returns one. + +GLFW comes with a test program that lets you control whole window transparency +at run-time called `opacity`. + + +@subsection window_attribs Window attributes + +Windows have a number of attributes that can be returned using @ref +glfwGetWindowAttrib. Some reflect state that may change as a result of user +interaction, (e.g. whether it has input focus), while others reflect inherent +properties of the window (e.g. what kind of border it has).

That means that you have two +rendering buffers; a front buffer and a back buffer. The front buffer is +the one being displayed and the back buffer the one you render to. + +When the entire frame has been rendered, it is time to swap the back and the +front buffers in order to display what has been rendered and begin rendering +a new frame. This is done with @ref glfwSwapBuffers. + +@code +glfwSwapBuffers(window); +@endcode + +Sometimes it can be useful to select when the buffer swap will occur. With the +function @ref glfwSwapInterval it is possible to select the minimum number of +monitor refreshes the driver wait should from the time @ref glfwSwapBuffers was +called before swapping the buffers: + +@code +glfwSwapInterval(1); +@endcode + +If the interval is zero, the swap will take place immediately when @ref +glfwSwapBuffers is called without waiting for a refresh. Otherwise at least +interval retraces will pass between each buffer swap. Using a swap interval of +zero can be useful for benchmarking purposes, when it is not desirable to +measure the time it takes to wait for the vertical retrace. However, a swap +interval of one lets you avoid tearing. + +Note that this may not work on all machines, as some drivers have +user-controlled settings that override any swap interval the application +requests. + +A context that supports either the `WGL_EXT_swap_control_tear` or the +`GLX_EXT_swap_control_tear` extension also accepts _negative_ swap intervals, +which allows the driver to swap immediately even if a frame arrives a little bit +late. This trades the risk of visible tears for greater framerate stability. +You can check for these extensions with @ref glfwExtensionSupported. + +*/ diff --git a/src/lib/third_party/glfw/OLD/examples/CMakeLists.txt b/src/lib/third_party/glfw/OLD/examples/CMakeLists.txt new file mode 100644 index 00000000..b458609f --- /dev/null +++ b/src/lib/third_party/glfw/OLD/examples/CMakeLists.txt @@ -0,0 +1,77 @@ + +link_libraries(glfw) + +include_directories(${glfw_INCLUDE_DIRS} "${GLFW_SOURCE_DIR}/deps") + +if (MATH_LIBRARY) + link_libraries("${MATH_LIBRARY}") +endif() + +if (MSVC) + add_definitions(-D_CRT_SECURE_NO_WARNINGS) +endif() + +if (GLFW_USE_OSMESA) + add_definitions(-DUSE_NATIVE_OSMESA) +endif() + +if (WIN32) + set(ICON glfw.rc) +elseif (APPLE) + set(ICON glfw.icns) + set_source_files_properties(glfw.icns PROPERTIES + MACOSX_PACKAGE_LOCATION "Resources") +endif() + +set(GLAD "${GLFW_SOURCE_DIR}/deps/glad/glad.h" + "${GLFW_SOURCE_DIR}/deps/glad.c") +set(GETOPT "${GLFW_SOURCE_DIR}/deps/getopt.h" + "${GLFW_SOURCE_DIR}/deps/getopt.c") +set(TINYCTHREAD "${GLFW_SOURCE_DIR}/deps/tinycthread.h" + "${GLFW_SOURCE_DIR}/deps/tinycthread.c") + +add_executable(boing WIN32 MACOSX_BUNDLE boing.c ${ICON} ${GLAD}) +add_executable(gears WIN32 MACOSX_BUNDLE gears.c ${ICON} ${GLAD}) +add_executable(heightmap WIN32 MACOSX_BUNDLE heightmap.c ${ICON} ${GLAD}) +add_executable(offscreen offscreen.c ${ICON} ${GLAD}) +add_executable(particles WIN32 MACOSX_BUNDLE particles.c ${ICON} ${TINYCTHREAD} ${GETOPT} ${GLAD}) +add_executable(sharing WIN32 MACOSX_BUNDLE sharing.c ${ICON} ${GLAD}) +add_executable(simple WIN32 MACOSX_BUNDLE simple.c ${ICON} ${GLAD}) +add_executable(splitview WIN32 MACOSX_BUNDLE splitview.c ${ICON} ${GLAD}) +add_executable(wave WIN32 MACOSX_BUNDLE wave.c ${ICON} ${GLAD}) + +target_link_libraries(particles "${CMAKE_THREAD_LIBS_INIT}") +if (RT_LIBRARY) + target_link_libraries(particles "${RT_LIBRARY}") +endif() + +set(WINDOWS_BINARIES boing gears heightmap particles sharing simple splitview wave) +set(CONSOLE_BINARIES offscreen) + +set_target_properties(${WINDOWS_BINARIES} ${CONSOLE_BINARIES} PROPERTIES + FOLDER "GLFW3/Examples") + +if (MSVC) + # Tell MSVC to use main instead of WinMain for Windows subsystem executables + set_target_properties(${WINDOWS_BINARIES} PROPERTIES + LINK_FLAGS "/ENTRY:mainCRTStartup") +endif() + +if (APPLE) + set_target_properties(boing PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Boing") + set_target_properties(gears PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Gears") + set_target_properties(heightmap PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Heightmap") + set_target_properties(particles PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Particles") + set_target_properties(sharing PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Sharing") + set_target_properties(simple PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Simple") + set_target_properties(splitview PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "SplitView") + set_target_properties(wave PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Wave") + + set_target_properties(${WINDOWS_BINARIES} PROPERTIES + RESOURCE glfw.icns + MACOSX_BUNDLE_SHORT_VERSION_STRING ${GLFW_VERSION} + MACOSX_BUNDLE_LONG_VERSION_STRING ${GLFW_VERSION_FULL} + MACOSX_BUNDLE_ICON_FILE glfw.icns + MACOSX_BUNDLE_INFO_PLIST "${GLFW_SOURCE_DIR}/CMake/MacOSXBundleInfo.plist.in") +endif() + diff --git a/src/lib/third_party/glfw/OLD/examples/boing.c b/src/lib/third_party/glfw/OLD/examples/boing.c new file mode 100644 index 00000000..45c867fd --- /dev/null +++ b/src/lib/third_party/glfw/OLD/examples/boing.c @@ -0,0 +1,678 @@ +/***************************************************************************** + * Title: GLBoing + * Desc: Tribute to Amiga Boing. + * Author: Jim Brooks + * Original Amiga authors were R.J.

For more information on how + * to query connected monitors, see @ref monitor_monitors. + * + * For full screen windows, the specified size becomes the resolution of the + * window's _desired video mode_. As long as a full screen window is not + * iconified, the supported video mode most closely matching the desired video + * mode is set for the specified monitor. For more information about full + * screen windows, including the creation of so called _windowed full screen_ + * or _borderless full screen_ windows, see @ref window_windowed_full_screen. + * + * Once you have created the window, you can switch it between windowed and + * full screen mode with @ref glfwSetWindowMonitor. This will not affect its + * OpenGL or OpenGL ES context. + * + * By default, newly created windows use the placement recommended by the + * window system. To create the window at a specific position, make it + * initially invisible using the [GLFW_VISIBLE](@ref GLFW_VISIBLE_hint) window + * hint, set its [position](@ref window_pos) and then [show](@ref window_hide) + * it. + * + * As long as at least one full screen window is not iconified, the screensaver + * is prohibited from starting. + * + * Window systems put limits on window sizes.

This is a minimal state graphical user interface single header toolkit - written in ANSI C and licensed under public domain. - It was designed as a simple embeddable user interface for application and does - not have any dependencies, a default renderbackend or OS window and input handling - but instead provides a very modular library approach by using simple input state - for input and draw commands describing primitive shapes as output. - So instead of providing a layered library that tries to abstract over a number - of platform and render backends it only focuses on the actual UI. - -VALUES: - - Graphical user interface toolkit - - Single header library - - Written in C89 (a.k.a. ANSI C or ISO C90) - - Small codebase (~18kLOC) - - Focus on portability, efficiency and simplicity - - No dependencies (not even the standard library if not wanted) - - Fully skinnable and customizable - - Low memory footprint with total memory control if needed or wanted - - UTF-8 support - - No global or hidden state - - Customizable library modules (you can compile and use only what you need) - - Optional font baker and vertex buffer output - -USAGE: - This library is self contained in one single header file and can be used either - in header only mode or in implementation mode. The header only mode is used - by default when included and allows including this header in other headers - and does not contain the actual implementation. - - The implementation mode requires to define the preprocessor macro - NK_IMPLEMENTATION in *one* .c/.cpp file before #includeing this file, e.g.: - - #define NK_IMPLEMENTATION - #include "nuklear.h" - - Also optionally define the symbols listed in the section "OPTIONAL DEFINES" - below in header and implementation mode if you want to use additional functionality - or need more control over the library. - IMPORTANT: Every time you include "nuklear.h" you have to define the same flags. - This is very important not doing it either leads to compiler errors - or even worse stack corruptions. - -FEATURES: - - Absolutely no platform dependent code - - Memory management control ranging from/to - - Ease of use by allocating everything from standard library - - Control every byte of memory inside the library - - Font handling control ranging from/to - - Use your own font implementation for everything - - Use this libraries internal font baking and handling API - - Drawing output control ranging from/to - - Simple shapes for more high level APIs which already have drawing capabilities - - Hardware accessible anti-aliased vertex buffer output - - Customizable colors and properties ranging from/to - - Simple changes to color by filling a simple color table - - Complete control with ability to use skinning to decorate widgets - - Bendable UI library with widget ranging from/to - - Basic widgets like buttons, checkboxes, slider, ... - - Advanced widget like abstract comboboxes, contextual menus,... - - Compile time configuration to only compile what you need - - Subset which can be used if you do not want to link or use the standard library - - Can be easily modified to only update on user input instead of frame updates - -OPTIONAL DEFINES: - NK_PRIVATE - If defined declares all functions as static, so they can only be accessed - inside the file that contains the implementation - - NK_INCLUDE_FIXED_TYPES - If defined it will include header for fixed sized types - otherwise nuklear tries to select the correct type. If that fails it will - throw a compiler error and you have to select the correct types yourself. - If used needs to be defined for implementation and header - - NK_INCLUDE_DEFAULT_ALLOCATOR - if defined it will include header and provide additional functions - to use this library without caring for memory allocation control and therefore - ease memory management. - Adds the standard library with malloc and free so don't define if you - don't want to link to the standard library - If used needs to be defined for implementation and header - - NK_INCLUDE_STANDARD_IO - if defined it will include header and provide - additional functions depending on file loading. - Adds the standard library with fopen, fclose,... so don't define this - if you don't want to link to the standard library - If used needs to be defined for implementation and header - - NK_INCLUDE_STANDARD_VARARGS - if defined it will include header and provide - additional functions depending on variable arguments - Adds the standard library with va_list and so don't define this if - you don't want to link to the standard library - If used needs to be defined for implementation and header - - NK_INCLUDE_VERTEX_BUFFER_OUTPUT - Defining this adds a vertex draw command list backend to this - library, which allows you to convert queue commands into vertex draw commands. - This is mainly if you need a hardware accessible format for OpenGL, DirectX, - Vulkan, Metal,... - If used needs to be defined for implementation and header - - NK_INCLUDE_FONT_BAKING - Defining this adds `stb_truetype` and `stb_rect_pack` implementation - to this library and provides font baking and rendering. - If you already have font handling or do not want to use this font handler - you don't have to define it. - If used needs to be defined for implementation and header - - NK_INCLUDE_DEFAULT_FONT - Defining this adds the default font: ProggyClean.ttf into this library - which can be loaded into a font atlas and allows using this library without - having a truetype font - Enabling this adds ~12kb to global stack memory - If used needs to be defined for implementation and header - - NK_INCLUDE_COMMAND_USERDATA - Defining this adds a userdata pointer into each command. Can be useful for - example if you want to provide custom shaders depending on the used widget. - Can be combined with the style structures. - If used needs to be defined for implementation and header - - NK_BUTTON_TRIGGER_ON_RELEASE - Different platforms require button clicks occurring either on buttons being - pressed (up to down) or released (down to up). - By default this library will react on buttons being pressed, but if you - define this it will only trigger if a button is released. - If used it is only required to be defined for the implementation part - - NK_ZERO_COMMAND_MEMORY - Defining this will zero out memory for each drawing command added to a - drawing queue (inside nk_command_buffer_push). Zeroing command memory - is very useful for fast checking (using memcmp) if command buffers are - equal and avoid drawing frames when nothing on screen has changed since - previous frame. - - NK_ASSERT - If you don't define this, nuklear will use with assert(). - Adds the standard library so define to nothing of not wanted - If used needs to be defined for implementation and header - - NK_BUFFER_DEFAULT_INITIAL_SIZE - Initial buffer size allocated by all buffers while using the default allocator - functions included by defining NK_INCLUDE_DEFAULT_ALLOCATOR.

This includes at least - * filled and stroked rectangles, circles, text, lines, triangles and scissors. - * As soon as this criterion is met you can iterate over each draw command - * and execute each draw command in a interpreter like fashion: - * - * const struct nk_command *cmd = 0; - * nk_foreach(cmd, &ctx) { - * switch (cmd->type) { - * case NK_COMMAND_LINE: - * your_draw_line_function(...) - * break; - * case NK_COMMAND_RECT - * your_draw_rect_function(...) - * break; - * case ...: - * [...] - * } - * - * In program flow context draw commands need to be executed after input has been - * gathered and the complete UI with windows and their contained widgets have - * been executed and before calling `nk_clear` which frees all previously - * allocated draw commands. - * - * struct nk_context ctx; - * nk_init_xxx(&ctx, ...); - * while (1) { - * Event evt; - * nk_input_begin(&ctx); - * while (GetEvent(&evt)) { - * if (evt.type == MOUSE_MOVE) - * nk_input_motion(&ctx, evt.motion.x, evt.motion.y); - * else if (evt.type == [...]) { - * [...] - * } - * } - * nk_input_end(&ctx); - * - * [...] - * - * const struct nk_command *cmd = 0; - * nk_foreach(cmd, &ctx) { - * switch (cmd->type) { - * case NK_COMMAND_LINE: - * your_draw_line_function(...) - * break; - * case NK_COMMAND_RECT - * your_draw_rect_function(...) - * break; - * case ...: - * [...] - * } - * nk_clear(&ctx); - * } - * nk_free(&ctx); - * - * You probably noticed that you have to draw all of the UI each frame which is - * quite wasteful. While the actual UI updating loop is quite fast rendering - * without actually needing it is not. So there are multiple things you could do. - * - * First is only update on input. This of course is only an option if your - * application only depends on the UI and does not require any outside calculations. - * If you actually only update on input make sure to update the UI two times each - * frame and call `nk_clear` directly after the first pass and only draw in - * the second pass.

Instead all drawn shapes, widgets +/// are made of, are buffered into memory and make up a command queue. +/// Each frame therefore fills the command buffer with draw commands +/// that then need to be executed by the user and his own render backend. +/// After that the command buffer needs to be cleared and a new frame can be +/// started. It is probably important to note that the command buffer is the main +/// drawing API and the optional vertex buffer API only takes this format and +/// converts it into a hardware accessible format. +/// +/// #### Usage +/// To draw all draw commands accumulated over a frame you need your own render +/// backend able to draw a number of 2D primitives.

Furthermore it +/// is recommended to check the return value of `nk_begin_xxx` and only process +/// widgets inside the window if the value is not 0. Either way you have to call +/// `nk_end` at the end of window declarations. Furthermore, do not attempt to +/// nest `nk_begin_xxx` calls which will hopefully result in an assert or if not +/// in a segmentation fault. +/// +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c +/// if (nk_begin_xxx(...) { +/// // [... widgets ...] +/// } +/// nk_end(ctx); +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +/// +/// In the grand concept window and widget declarations need to occur after input +/// handling and before drawing to screen. Not doing so can result in higher +/// latency or at worst invalid behavior. Furthermore make sure that `nk_clear` +/// is called at the end of the frame.

It provides each - * widgets with same horizontal space inside the row and dynamically grows - * if the owning window grows in width. So the number of columns dictates - * the size of each widget dynamically by formula: - * - * widget_width = (window_width - padding - spacing) * (1/colum_count) - * - * Just like all other layouting APIs if you define more widget than columns this - * library will allocate a new row and keep all layouting parameters previously - * defined. - * - * if (nk_begin_xxx(...) { - * // first row with height: 30 composed of two widgets - * nk_layout_row_dynamic(&ctx, 30, 2); - * nk_widget(...); - * nk_widget(...); - * - * // second row with same parameter as defined above - * nk_widget(...); - * nk_widget(...); - * - * // third row uses 0 for height which will use auto layouting - * nk_layout_row_dynamic(&ctx, 0, 2); - * nk_widget(...); - * nk_widget(...); - * } - * nk_end(...); - * - * 2.) nk_layout_row_static - * Another easy layouting function is `nk_layout_row_static`. It provides each - * widget with same horizontal pixel width inside the row and does not grow - * if the owning window scales smaller or bigger. - * - * if (nk_begin_xxx(...) { - * // first row with height: 30 composed of two widgets with width: 80 - * nk_layout_row_static(&ctx, 30, 80, 2); - * nk_widget(...); - * nk_widget(...); - * - * // second row with same parameter as defined above - * nk_widget(...); - * nk_widget(...); - * - * // third row uses 0 for height which will use auto layouting - * nk_layout_row_static(&ctx, 0, 80, 2); - * nk_widget(...); - * nk_widget(...); - * } - * nk_end(...); - * - * 3.) nk_layout_row_xxx - * A little bit more advanced layouting API are functions `nk_layout_row_begin`, - * `nk_layout_row_push` and `nk_layout_row_end`. They allow to directly - * specify each column pixel or window ratio in a row. It supports either - * directly setting per column pixel width or widget window ratio but not - * both. Furthermore it is a immediate mode API so each value is directly - * pushed before calling a widget. Therefore the layout is not automatically - * repeating like the last two layouting functions. - * - * if (nk_begin_xxx(...) { - * // first row with height: 25 composed of two widgets with width 60 and 40 - * nk_layout_row_begin(ctx, NK_STATIC, 25, 2); - * nk_layout_row_push(ctx, 60); - * nk_widget(...); - * nk_layout_row_push(ctx, 40); - * nk_widget(...); - * nk_layout_row_end(ctx); - * - * // second row with height: 25 composed of two widgets with window ratio 0.25 and 0.75 - * nk_layout_row_begin(ctx, NK_DYNAMIC, 25, 2); - * nk_layout_row_push(ctx, 0.25f); - * nk_widget(...); - * nk_layout_row_push(ctx, 0.75f); - * nk_widget(...); - * nk_layout_row_end(ctx); - * - * // third row with auto generated height: composed of two widgets with window ratio 0.25 and 0.75 - * nk_layout_row_begin(ctx, NK_DYNAMIC, 0, 2); - * nk_layout_row_push(ctx, 0.25f); - * nk_widget(...); - * nk_layout_row_push(ctx, 0.75f); - * nk_widget(...); - * nk_layout_row_end(ctx); - * } - * nk_end(...); - * - * 4.) nk_layout_row - * The array counterpart to API nk_layout_row_xxx is the single nk_layout_row - * functions. Instead of pushing either pixel or window ratio for every widget - * it allows to define it by array. The trade of for less control is that - * `nk_layout_row` is automatically repeating. Otherwise the behavior is the - * same. - * - * if (nk_begin_xxx(...) { - * // two rows with height: 30 composed of two widgets with width 60 and 40 - * const float size[] = {60,40}; - * nk_layout_row(ctx, NK_STATIC, 30, 2, ratio); - * nk_widget(...); - * nk_widget(...); - * nk_widget(...); - * nk_widget(...); - * - * // two rows with height: 30 composed of two widgets with window ratio 0.25 and 0.75 - * const float ratio[] = {0.25, 0.75}; - * nk_layout_row(ctx, NK_DYNAMIC, 30, 2, ratio); - * nk_widget(...); - * nk_widget(...); - * nk_widget(...); - * nk_widget(...); - * - * // two rows with auto generated height composed of two widgets with window ratio 0.25 and 0.75 - * const float ratio[] = {0.25, 0.75}; - * nk_layout_row(ctx, NK_DYNAMIC, 30, 2, ratio); - * nk_widget(...); - * nk_widget(...); - * nk_widget(...); - * nk_widget(...); - * } - * nk_end(...); - * - * 5.) nk_layout_row_template_xxx - * The most complex and second most flexible API is a simplified flexbox version without - * line wrapping and weights for dynamic widgets. It is an immediate mode API but - * unlike `nk_layout_row_xxx` it has auto repeat behavior and needs to be called - * before calling the templated widgets. - * The row template layout has three different per widget size specifier. The first - * one is the static widget size specifier with fixed widget pixel width. They do - * not grow if the row grows and will always stay the same. The second size - * specifier is nk_layout_row_template_push_variable which defines a - * minimum widget size but it also can grow if more space is available not taken - * by other widgets. Finally there are dynamic widgets which are completely flexible - * and unlike variable widgets can even shrink to zero if not enough space - * is provided. - * - * if (nk_begin_xxx(...) { - * // two rows with height: 30 composed of three widgets - * nk_layout_row_template_begin(ctx, 30); - * nk_layout_row_template_push_dynamic(ctx); - * nk_layout_row_template_push_variable(ctx, 80); - * nk_layout_row_template_push_static(ctx, 80); - * nk_layout_row_template_end(ctx); - * - * nk_widget(...); // dynamic widget can go to zero if not enough space - * nk_widget(...); // variable widget with min 80 pixel but can grow bigger if enough space - * nk_widget(...); // static widget with fixed 80 pixel width - * - * // second row same layout - * nk_widget(...); - * nk_widget(...); - * nk_widget(...); - * } - * nk_end(...); - * - * 6.) nk_layout_space_xxx - * Finally the most flexible API directly allows you to place widgets inside the - * window. The space layout API is an immediate mode API which does not support - * row auto repeat and directly sets position and size of a widget. Position - * and size hereby can be either specified as ratio of allocated space or - * allocated space local position and pixel size. Since this API is quite - * powerful there are a number of utility functions to get the available space - * and convert between local allocated space and screen space. - * - * if (nk_begin_xxx(...) { - * // static row with height: 500 (you can set column count to INT_MAX if you don't want to be bothered) - * nk_layout_space_begin(ctx, NK_STATIC, 500, INT_MAX); - * nk_layout_space_push(ctx, nk_rect(0,0,150,200)); - * nk_widget(...); - * nk_layout_space_push(ctx, nk_rect(200,200,100,200)); - * nk_widget(...); - * nk_layout_space_end(ctx); - * - * // dynamic row with height: 500 (you can set column count to INT_MAX if you don't want to be bothered) - * nk_layout_space_begin(ctx, NK_DYNAMIC, 500, INT_MAX); - * nk_layout_space_push(ctx, nk_rect(0.5,0.5,0.1,0.1)); - * nk_widget(...); - * nk_layout_space_push(ctx, nk_rect(0.7,0.6,0.1,0.1)); - * nk_widget(...); - * } - * nk_end(...); - * - * Reference - * ------------------- - * nk_layout_set_min_row_height - set the currently used minimum row height to a specified value - * nk_layout_reset_min_row_height - resets the currently used minimum row height to font height - * - * nk_layout_widget_bounds - calculates current width a static layout row can fit inside a window - * nk_layout_ratio_from_pixel - utility functions to calculate window ratio from pixel size - * - * nk_layout_row_dynamic - current layout is divided into n same sized growing columns - * nk_layout_row_static - current layout is divided into n same fixed sized columns - * nk_layout_row_begin - starts a new row with given height and number of columns - * nk_layout_row_push - pushes another column with given size or window ratio - * nk_layout_row_end - finished previously started row - * nk_layout_row - specifies row columns in array as either window ratio or size - * - * nk_layout_row_template_begin - begins the row template declaration - * nk_layout_row_template_push_dynamic - adds a dynamic column that dynamically grows and can go to zero if not enough space - * nk_layout_row_template_push_variable - adds a variable column that dynamically grows but does not shrink below specified pixel width - * nk_layout_row_template_push_static - adds a static column that does not grow and will always have the same size - * nk_layout_row_template_end - marks the end of the row template - * - * nk_layout_space_begin - begins a new layouting space that allows to specify each widgets position and size - * nk_layout_space_push - pushes position and size of the next widget in own coordinate space either as pixel or ratio - * nk_layout_space_end - marks the end of the layouting space - * - * nk_layout_space_bounds - callable after nk_layout_space_begin and returns total space allocated - * nk_layout_space_to_screen - converts vector from nk_layout_space coordinate space into screen space - * nk_layout_space_to_local - converts vector from screen space into nk_layout_space coordinates - * nk_layout_space_rect_to_screen - converts rectangle from nk_layout_space coordinate space into screen space - * nk_layout_space_rect_to_local - converts rectangle from screen space into nk_layout_space coordinates - */ -/* nk_layout_set_min_row_height - sets the currently used minimum row height. - * IMPORTANT: The passed height needs to include both your preferred row height - * as well as padding.

Otherwise the behavior is the +/// same. +/// +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c +/// if (nk_begin_xxx(...) { +/// // two rows with height: 30 composed of two widgets with width 60 and 40 +/// const float size[] = {60,40}; +/// nk_layout_row(ctx, NK_STATIC, 30, 2, ratio); +/// nk_widget(...); +/// nk_widget(...); +/// nk_widget(...); +/// nk_widget(...); +/// // +/// // two rows with height: 30 composed of two widgets with window ratio 0.25 and 0.75 +/// const float ratio[] = {0.25, 0.75}; +/// nk_layout_row(ctx, NK_DYNAMIC, 30, 2, ratio); +/// nk_widget(...); +/// nk_widget(...); +/// nk_widget(...); +/// nk_widget(...); +/// // +/// // two rows with auto generated height composed of two widgets with window ratio 0.25 and 0.75 +/// const float ratio[] = {0.25, 0.75}; +/// nk_layout_row(ctx, NK_DYNAMIC, 30, 2, ratio); +/// nk_widget(...); +/// nk_widget(...); +/// nk_widget(...); +/// nk_widget(...); +/// } +/// nk_end(...); +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +/// +/// 5. __nk_layout_row_template_xxx__

+/// The most complex and second most flexible API is a simplified flexbox version without +/// line wrapping and weights for dynamic widgets. It is an immediate mode API but +/// unlike `nk_layout_row_xxx` it has auto repeat behavior and needs to be called +/// before calling the templated widgets. +/// The row template layout has three different per widget size specifier. The first +/// one is the `nk_layout_row_template_push_static` with fixed widget pixel width. +/// They do not grow if the row grows and will always stay the same. +/// The second size specifier is `nk_layout_row_template_push_variable` +/// which defines a minimum widget size but it also can grow if more space is available +/// not taken by other widgets. +/// Finally there are dynamic widgets with `nk_layout_row_template_push_dynamic` +/// which are completely flexible and unlike variable widgets can even shrink +/// to zero if not enough space is provided. +/// +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c +/// if (nk_begin_xxx(...) { +/// // two rows with height: 30 composed of three widgets +/// nk_layout_row_template_begin(ctx, 30); +/// nk_layout_row_template_push_dynamic(ctx); +/// nk_layout_row_template_push_variable(ctx, 80); +/// nk_layout_row_template_push_static(ctx, 80); +/// nk_layout_row_template_end(ctx); +/// // +/// // first row +/// nk_widget(...); // dynamic widget can go to zero if not enough space +/// nk_widget(...); // variable widget with min 80 pixel but can grow bigger if enough space +/// nk_widget(...); // static widget with fixed 80 pixel width +/// // +/// // second row same layout +/// nk_widget(...); +/// nk_widget(...); +/// nk_widget(...); +/// } +/// nk_end(...); +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +/// +/// 6. __nk_layout_space_xxx__

+/// Finally the most flexible API directly allows you to place widgets inside the +/// window. The space layout API is an immediate mode API which does not support +/// row auto repeat and directly sets position and size of a widget. Position +/// and size hereby can be either specified as ratio of allocated space or +/// allocated space local position and pixel size.

First the concept of a collapsable +/// UI section that can be either in a hidden or visibile state. They allow the UI +/// user to selectively minimize the current set of visible UI to comprehend. +/// The second concept are tree widgets for visual UI representation of trees.

+/// +/// Trees thereby can be nested for tree representations and multiple nested +/// collapsable UI sections. All trees are started by calling of the +/// `nk_tree_xxx_push_tree` functions and ended by calling one of the +/// `nk_tree_xxx_pop_xxx()` functions. Each starting functions takes a title label +/// and optionally an image to be displayed and the initial collapse state from +/// the nk_collapse_states section.

+/// +/// The runtime state of the tree is either stored outside the library by the caller +/// or inside which requires a unique ID. The unique ID can either be generated +/// automatically from `__FILE__` and `__LINE__` with function `nk_tree_push`, +/// by `__FILE__` and a user provided ID generated for example by loop index with +/// function `nk_tree_push_id` or completely provided from outside by user with +/// function `nk_tree_push_hashed`. +/// +/// #### Usage +/// To create a tree you have to call one of the seven `nk_tree_xxx_push_xxx` +/// functions to start a collapsable UI section and `nk_tree_xxx_pop` to mark the +/// end. +/// Each starting function will either return `false(0)` if the tree is collapsed +/// or hidden and therefore does not need to be filled with content or `true(1)` +/// if visible and required to be filled. +/// +/// !!!

If you need a row smaller than +/// that you can directly set it by `nk_layout_set_min_row_height` and +/// reset the value back by calling `nk_layout_reset_min_row_height. +/// - 2017/06/08 (1.39.1) - Fixed property text edit handling bug caused by past `nk_widget` fix +/// - 2017/06/08 (1.39.0) - Added function to retrieve window space without calling a nk_layout_xxx function +/// - 2017/06/06 (1.38.5) - Fixed `nk_convert` return flag for command buffer +/// - 2017/05/23 (1.38.4) - Fixed activation behavior for widgets partially clipped +/// - 2017/05/10 (1.38.3) - Fixed wrong min window size mouse scaling over boundries +/// - 2017/05/09 (1.38.2) - Fixed vertical scrollbar drawing with not enough space +/// - 2017/05/09 (1.38.1) - Fixed scaler dragging behavior if window size hits minimum size +/// - 2017/05/06 (1.38.0) - Added platform double-click support +/// - 2017/04/20 (1.37.1) - Fixed key repeat found inside glfw demo backends +/// - 2017/04/20 (1.37.0) - Extended properties with selection and clipbard support +/// - 2017/04/20 (1.36.2) - Fixed #405 overlapping rows with zero padding and spacing +/// - 2017/04/09 (1.36.1) - Fixed #403 with another widget float error +/// - 2017/04/09 (1.36.0) - Added window `NK_WINDOW_NO_INPUT` and `NK_WINDOW_NOT_INTERACTIVE` flags +/// - 2017/04/09 (1.35.3) - Fixed buffer heap corruption +/// - 2017/03/25 (1.35.2) - Fixed popup overlapping for `NK_WINDOW_BACKGROUND` windows +/// - 2017/03/25 (1.35.1) - Fixed windows closing behavior +/// - 2017/03/18 (1.35.0) - Added horizontal scroll requested in #377 +/// - 2017/03/18 (1.34.3) - Fixed long window header titles +/// - 2017/03/04 (1.34.2) - Fixed text edit filtering +/// - 2017/03/04 (1.34.1) - Fixed group closable flag +/// - 2017/02/25 (1.34.0) - Added custom draw command for better language binding support +/// - 2017/01/24 (1.33.0) - Added programatic way of remove edit focus +/// - 2017/01/24 (1.32.3) - Fixed wrong define for basic type definitions for windows +/// - 2017/01/21 (1.32.2) - Fixed input capture from hidden or closed windows +/// - 2017/01/21 (1.32.1) - Fixed slider behavior and drawing +/// - 2017/01/13 (1.32.0) - Added flag to put scaler into the bottom left corner +/// - 2017/01/13 (1.31.0) - Added additional row layouting method to combine both +/// dynamic and static widgets. +/// - 2016/12/31 (1.30.0) - Extended scrollbar offset from 16-bit to 32-bit +/// - 2016/12/31 (1.29.2)- Fixed closing window bug of minimized windows +/// - 2016/12/03 (1.29.1)- Fixed wrapped text with no seperator and C89 error +/// - 2016/12/03 (1.29.0) - Changed text wrapping to process words not characters +/// - 2016/11/22 (1.28.6)- Fixed window minimized closing bug +/// - 2016/11/19 (1.28.5)- Fixed abstract combo box closing behavior +/// - 2016/11/19 (1.28.4)- Fixed tooltip flickering +/// - 2016/11/19 (1.28.3)- Fixed memory leak caused by popup repeated closing +/// - 2016/11/18 (1.28.2)- Fixed memory leak caused by popup panel allocation +/// - 2016/11/10 (1.28.1)- Fixed some warnings and C++ error +/// - 2016/11/10 (1.28.0)- Added additional `nk_button` versions which allows to directly +/// pass in a style struct to change buttons visual. +/// - 2016/11/10 (1.27.0)- Added additional 'nk_tree' versions to support external state +/// storage. Just like last the `nk_group` commit the main +/// advantage is that you optionally can minimize nuklears runtime +/// memory consumption or handle hash collisions. +/// - 2016/11/09 (1.26.0)- Added additional `nk_group` version to support external scrollbar +/// offset storage. Main advantage is that you can externalize +/// the memory management for the offset. It could also be helpful +/// if you have a hash collision in `nk_group_begin` but really +/// want the name. In addition I added `nk_list_view` which allows +/// to draw big lists inside a group without actually having to +/// commit the whole list to nuklear (issue #269). +/// - 2016/10/30 (1.25.1)- Fixed clipping rectangle bug inside `nk_draw_list` +/// - 2016/10/29 (1.25.0)- Pulled `nk_panel` memory management into nuklear and out of +/// the hands of the user.

If you +/// still need the panel just call `nk_window_get_panel`. +/// - 2016/10/21 (1.24.0)- Changed widget border drawing to stroked rectangle from filled +/// rectangle for less overdraw and widget background transparency. +/// - 2016/10/18 (1.23.0)- Added `nk_edit_focus` for manually edit widget focus control +/// - 2016/09/29 (1.22.7)- Fixed deduction of basic type in non `` compilation +/// - 2016/09/29 (1.22.6)- Fixed edit widget UTF-8 text cursor drawing bug +/// - 2016/09/28 (1.22.5)- Fixed edit widget UTF-8 text appending/inserting/removing +/// - 2016/09/28 (1.22.4)- Fixed drawing bug inside edit widgets which offset all text +/// text in every edit widget if one of them is scrolled. +/// - 2016/09/28 (1.22.3)- Fixed small bug in edit widgets if not active. The wrong +/// text length is passed. It should have been in bytes but +/// was passed as glyphes. +/// - 2016/09/20 (1.22.2)- Fixed color button size calculation +/// - 2016/09/20 (1.22.1)- Fixed some `nk_vsnprintf` behavior bugs and removed +/// `` again from `NK_INCLUDE_STANDARD_VARARGS`. +/// - 2016/09/18 (1.22.0)- C89 does not support vsnprintf only C99 and newer as well +/// as C++11 and newer. In addition to use vsnprintf you have +/// to include . So just defining `NK_INCLUDE_STD_VAR_ARGS` +/// is not enough. That behavior is now fixed. By default if +/// both varargs as well as stdio is selected I try to use +/// vsnprintf if not possible I will revert to vsprintf. If +/// varargs but not stdio was defined I will use my own function. +/// - 2016/09/15 (1.21.2)- Fixed panel `close` behavior for deeper panel levels +/// - 2016/09/15 (1.21.1)- Fixed C++ errors and wrong argument to `nk_panel_get_xxxx` +/// - 2016/09/13 (1.21.0) - !BREAKING! Fixed nonblocking popup behavior in menu, combo, +/// and contextual which prevented closing in y-direction if +/// popup did not reach max height. +/// In addition the height parameter was changed into vec2 +/// for width and height to have more control over the popup size. +/// - 2016/09/13 (1.20.3) - Cleaned up and extended type selection +/// - 2016/09/13 (1.20.2)- Fixed slider behavior hopefully for the last time. This time +/// all calculation are correct so no more hackery. +/// - 2016/09/13 (1.20.1)- Internal change to divide window/panel flags into panel flags and types. +/// Suprisinly spend years in C and still happened to confuse types +/// with flags. Probably something to take note. +/// - 2016/09/08 (1.20.0)- Added additional helper function to make it easier to just +/// take the produced buffers from `nk_convert` and unplug the +/// iteration process from `nk_context`. So now you can +/// just use the vertex,element and command buffer + two pointer +/// inside the command buffer retrieved by calls `nk__draw_begin` +/// and `nk__draw_end` and macro `nk_draw_foreach_bounded`. +/// - 2016/09/08 (1.19.0)- Added additional asserts to make sure every `nk_xxx_begin` call +/// for windows, popups, combobox, menu and contextual is guarded by +/// `if` condition and does not produce false drawing output. +/// - 2016/09/08 (1.18.0)- Changed confusing name for `NK_SYMBOL_RECT_FILLED`, `NK_SYMBOL_RECT` +/// to hopefully easier to understand `NK_SYMBOL_RECT_FILLED` and +/// `NK_SYMBOL_RECT_OUTLINE`. +/// - 2016/09/08 (1.17.0)- Changed confusing name for `NK_SYMBOL_CIRLCE_FILLED`, `NK_SYMBOL_CIRCLE` +/// to hopefully easier to understand `NK_SYMBOL_CIRCLE_FILLED` and +/// `NK_SYMBOL_CIRCLE_OUTLINE`. +/// - 2016/09/08 (1.16.0)- Added additional checks to select correct types if `NK_INCLUDE_FIXED_TYPES` +/// is not defined by supporting the biggest compiler GCC, clang and MSVC. +/// - 2016/09/07 (1.15.3)- Fixed `NK_INCLUDE_COMMAND_USERDATA` define to not cause an error +/// - 2016/09/04 (1.15.2)- Fixed wrong combobox height calculation +/// - 2016/09/03 (1.15.1)- Fixed gaps inside combo boxes in OpenGL +/// - 2016/09/02 (1.15.0) - Changed nuklear to not have any default vertex layout and +/// instead made it user provided.
