Please
	1) let me know
	- if you are including tiny file dialogs,
	  I'll be happy to add your link to the list of projects using it.
	- If you are using it on different hardware / OS / compiler.
	2) leave a review on Sourceforge. Thanks.

tiny file dialogs (cross-platform C C++)
InputBox PasswordBox MessageBox ColorPicker
OpenFileDialog SaveFileDialog SelectFolderDialog
Native dialog library for WINDOWS MAC OSX GTK+ QT CONSOLE & more
SSH supported via automatic switch to console mode or X11 forwarding

One C file (add it to your C or C++ project) with 6 functions:
- message & question
- input & password
- save file
- open file(s)
- select folder
- color picker

Complements OpenGL GLFW GLUT GLUI VTK SFML TGUI SDL Ogre Unity3d ION OpenCV
CEGUI MathGL GLM CPW GLOW IMGUI MyGUI GLT NGL STB & GUI less programs

NO INIT
NO MAIN LOOP
NO LINKING
NO INCLUDE

The dialogs can be forced into console mode

Windows (XP to 10) ASCII MBCS UTF-8 UTF-16
- native code & vbs create the graphic dialogs
- enhanced console mode can use dialog.exe from
http://andrear.altervista.org/home/cdialog.php
- basic console input

Unix (command line calls) ASCII UTF-8
- applescript
- zenity / matedialog / qarma (zenity for qt)
- kdialog
- Xdialog
- python2 tkinter
- dialog (opens a console if needed)
- basic console input
The same executable can run across desktops & distributions

tested with C & C++ compilers
on VisualStudio MinGW Mac Linux Bsd Solaris Minix Raspbian
using Gnome Kde Enlightenment Mate Cinnamon Unity
Lxde Lxqt Xfce WindowMaker IceWm Cde Jds OpenBox Awesome Jwm

bindings for LUA and C# dll
included in LWJGL(java), rust, Allegrobasic

/*
- This is not for android nor ios.
- The code is pure C, perfectly compatible with C++.
- the windows only wchar_t (utf-16) prototypes are in the header file
- windows is fully supported from XP to 10 (maybe even older versions)
- C# & LUA via dll, see example files
- OSX supported from 10.4 to 10.11 (maybe even older versions)
- Avoid using " and ' in titles and messages.
- There's one file filter only, it may contain several patterns.
- If no filter description is provided,
  the list of patterns will become the description.
- char const * filterPatterns[3] = { "*.obj" , "*.stl" , "*.dxf" } ;
- On windows link against Comdlg32.lib and Ole32.lib
  This linking is not compulsary for console mode (see above).
- On unix: it tries command line calls, so no such need.
- On unix you need applescript, zenity, matedialog, qarma, kdialog, Xdialog,
  python2/tkinter or dialog (will open a terminal if running without console).
- One of those is already included on most (if not all) desktops.
- In the absence of those it will use gdialog, gxmessage or whiptail
  with a textinputbox.
- If nothing is found, it switches to basic console input,
  it opens a console if needed (requires xterm + bash).
- Use windows separators on windows and unix separators on unix.
- String memory is preallocated statically for all the returned values.
- File and path names are tested before return, they are valid.
- If you pass only a path instead of path + filename,
  make sure it ends with a separator.
- tinyfd_forceConsole=1; at run time, forces dialogs into console mode.
- On windows, console mode only make sense for console applications.
- Mutiple selects are not allowed in console mode.
- The package dialog must be installed to run in enhanced console mode.
  It is already installed on most unix systems.
- On osx, the package dialog can be installed via http://macports.org
- On windows, for enhanced console mode,
  dialog.exe should be copied somewhere on your executable path.
  It can be found at the bottom of the following page:
  http://andrear.altervista.org/home/cdialog.php
- If dialog is missing, it will switch to basic console input.
- You can query the type of dialog that will be use.
- MinGW needs gcc >= v4.9 otherwise some headers are incomplete.
- The Hello World (and a bit more) is on the sourceforge site:
