QtImGui

Qt (QOpenGLWidget / QOpenGLWindow) backend for ImGui

It enables ImGui to run in QOpenGLWidget / QOpenGLWindow.

How to use

• Add QtImGui sources and headers to your project
  • If you are using git submodule, run git submodule update --init --recursive to ensure that the inner submodule is initialized as well.
• Add include(path/to/qtimgui.pri) to youre .pro file
• Subclass QOpenGLWindow or QOpenGLWidget and:

class DemoWindow : public QOpenGLWindow
{
protected:
    void initializeGL() override
    {
        QtImGui::initialize(this);
    }
    void paintGL() override
    {
        // you can do custom GL rendering as well in paintGL

        QtImGui::newFrame();

        ImGui::Text("Hello");
        // more widgets...

        ImGui::Render();
    }
};

See QOpenGLWidget example and QOpenGLWindow example for details.
