TempoApp

Template for building desktop app in C++ with Dear ImGui and GLFW.

This library takes care of the boilerplate for building desktop application with Dear ImGui, which is a bloat-free graphical user interface library for C++.

Features

• Multi-platform: Windows, Linux and MacOS (WIP)
• DPI aware (see Tempo::PushFont and Tempo::PopFont)
• Native file dialogs
• Thread safe event manager for passing messages between different parts of the application (see src/events.h)
• Multi-threaded task scheduler for launching non-blocking tasks (see src/jobscheduler.h)

Minimal example

Suppose that you have cloned this repository into a folder called TempoApp and you are using CMake for building the application.

CMakeLists.txt

# Set C++ 17 compiler flags
set(CMAKE_CXX_STANDARD 17)

# Set project name
project(minimal)

add_subdirectory(TempoApp)
include_directories(TempoApp/include)
include_directories(TempoApp/external/imgui/imgui)

add_executable(${PROJECT_NAME} main.cpp)
target_link_libraries(${PROJECT_NAME} PRIVATE Tempo)

main.cpp

#include <iostream>
#include <tempo.h>

class MainApp : public Tempo::App {
public:
    virtual ~MainApp() {}

    void FrameUpdate() override {
        ImGui::Begin("My window");

        if (ImGui::Button("Click me")) {
            std::cout << "Hello world" << std::endl;
        }

        ImGui::End();
    }
    void BeforeFrameUpdate() override {}
};

int main() {
    Tempo::Config config{
        .app_name = "TestApp",
        .app_title = "Hello world",
    };

    MainApp* app = new MainApp();
    Tempo::Run(app, config);

    return 0;
}
