  1. // dear imgui: Platform Backend for GLFW
  2. // This needs to be used along with a Renderer (e.g. OpenGL3, Vulkan, WebGPU..)
  3. // (Info: GLFW is a cross-platform general purpose library for handling windows, inputs, OpenGL/Vulkan graphics context creation, etc.)
  4. // Implemented features:
  5. // [X] Platform: Clipboard support.
  6. // [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen/Pen (Windows only).
  7. // [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy GLFW_KEY_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
  8. // [X] Platform: Gamepad support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
  9. // [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange' (note: the resizing cursors requires GLFW 3.4+).
  10. // You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
  11. // Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
