Wayland Interaction: GDK 3 Reference Manual

## Wayland Interaction Wayland Interaction — Wayland backend-specific functions |

## Includes

    #include <gdk/gdkwayland.h>

## Description

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).
