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
5// Implemented features:
6// [X] Platform: Clipboard support.
7// [X] Platform: Gamepad support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
8// [x] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'. FIXME: 3 cursors types are missing from GLFW.
9// [X] Platform: Keyboard arrays indexed using GLFW_KEY_* codes, e.g. ImGui::IsKeyPressed(GLFW_KEY_SPACE).
10
11// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
12// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
13// If you are new to Dear ImGui, read documentation from the docs/ folder + read the top of imgui.cpp.
14// Read online: https://github.com/ocornut/imgui/tree/master/docs

16// About GLSL version:
17// The 'glsl_version' initialization parameter defaults to "#version 150" if NULL.
18// Only override if your GL version doesn't handle this GLSL version. Keep NULL if unsure!
