|
|
* @Title: Wayland Interaction
|
|
*
|
|
* The functions in this section are specific to the GDK Wayland backend.
|
|
* To use them, you need to include the `<gdk/gdkwayland.h>` header and use
|
|
* the Wayland-specific pkg-config files to build your application (either
|
|
* `gdk-wayland-3.0` or `gtk+-wayland-3.0`).
|
|
*
|
|
* 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_WAYLAND_DISPLAY() macro).
