* @Short_description: macOS backend-specific functions
* @Title: macOS Interaction
* @Include: gdk/macos/gdkmacos.h
*
* The functions in this section are specific to the GDK macOS backend.
* To use them, you need to include the `<gdk/macos/gdkmacos.h>` header and
* use the macOS-specific pkg-config `gtk4-macos` file to build your
* application.
*
* To make your code compile with other GDK backends, guard backend-specific
* calls by an ifdef as follows. Since GDK may be built with multiple
* backends, you should also check for the backend that is in use (e.g. by
* using the GDK_IS_MACOS_DISPLAY() macro).
* |[<!-- language="C" -->
* #ifdef GDK_WINDOWING_MACOS
* if (GDK_IS_MACOS_DISPLAY (display))
* {
* // make macOS-specific calls here
* }
* else
* #endif
* #ifdef GDK_WINDOWING_X11
* if (GDK_IS_X11_DISPLAY (display))
* {
* // make X11-specific calls here
* }
* else
* #endif
