|
||
<p>The functions in this section are specific to the GDK Wayland backend.
|
||
To use them, you need to include the <code class="literal"><gdk/gdkwayland.h></code> header and use
|
||
the Wayland-specific pkg-config files to build your application (either
|
||
<code class="literal">gdk-wayland-3.0</code> or <code class="literal">gtk+-wayland-3.0</code>).</p>
|
||
<p>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 <code class="function">GDK_IS_WAYLAND_DISPLAY()</code> macro).</p>
