imgui_impl_osx.h

// dear imgui: Platform Backend for OSX / Cocoa
// This needs to be used along with a Renderer (e.g. OpenGL2, OpenGL3, Vulkan, Metal..)
// - Not well tested. If you want a portable application, prefer using the GLFW or SDL platform Backends on Mac.
// - Requires linking with the GameController framework ("-framework GameController").

// Implemented features:
//  [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
//  [X] Platform: Mouse support. Can discriminate Mouse/Pen.
//  [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 kVK_* values are obsolete since 1.87 and not supported since 1.91.5]
//  [X] Platform: OSX clipboard is supported within core Dear ImGui (no specific code in this backend).
//  [X] Platform: Gamepad support. Enabled with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
//  [X] Platform: IME support.

// 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.
