imgui_impl_glfw.h

// 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.)
// (Requires: GLFW 3.1+. Prefer GLFW 3.3+ for full feature support.)
 
// Implemented features:
//  [X] Platform: Clipboard support.
//  [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass KarmaGuiKey values to all key functions e.g. KarmaGui::IsKeyPressed(KarmaGuiKey_Space). [Legacy GLFW_KEY_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
//  [X] Platform: Gamepad support. Enable with 'io.ConfigFlags |= KarmaGuiConfigFlags_NavEnableGamepad'.
//  [x] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= KarmaGuiConfigFlags_NoMouseCursorChange' (note: the resizing cursors requires GLFW 3.4+).
//  [X] Platform: Multi-viewport support (multiple windows). Enable with 'io.ConfigFlags |= KarmaGuiConfigFlags_ViewportsEnable'.
 
// Issues:
//  [ ] Platform: Multi-viewport support: ParentViewportID not honored, and so io.ConfigViewportsNoDefaultParent has no effect (minor).
 
// 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.
// If you are new to Dear KarmaGui, read documentation from the docs/ folder + read the top of imgui.cpp.
