// dear imgui: Platform Backend for GLFW
|
|
// This needs to be used along with a Renderer (e.g. OpenGL3, Vulkan, WebGPU..)
|
|
// (Info: GLFW is a cross-platform general purpose library for handling windows, inputs, OpenGL/Vulkan graphics context creation, etc.)
|
|
|
|
// Implemented features:
|
|
// [X] Platform: Clipboard support.
|
|
// [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen/Pen (Windows only).
|
|
// [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 are obsolete since 1.87 and not supported since 1.91.5]
|
|
// [X] Platform: Gamepad support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
|
|
// [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange' (note: the resizing cursors requires GLFW 3.4+).
|
|
|
|
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
|
|
// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
|
|
