// dear imgui: Platform Backend for Windows (standard windows API for 32-bits AND 64-bits applications) |
|
// This needs to be used along with a Renderer (e.g. DirectX11, OpenGL3, Vulkan..) |
|
|
|
// Implemented features: |
|
// [X] Platform: Clipboard support (for Win32 this is actually part of core dear imgui) |
|
// [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen/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 VK_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set] |
|
// [X] Platform: Gamepad support. Enabled with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'. |
|
// [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'. |
|
|
|
// 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. |
|

// - In theory we could call simple functions from Windows SDK such as SetProcessDPIAware(), SetProcessDpiAwareness(), etc. |
|
// but most of the functions provided by Microsoft require Windows 8.1/10+ SDK at compile time and Windows 8/10+ at runtime, |
|
// neither we want to require the user to have. So we dynamically select and load those functions to avoid dependencies. |
