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> <div class="informalexample"> <table class="listing_frame" border="0" cellpadding="0" cellspacing="0"> <tbody> <tr> <td class="listing_lines" align="right"><pre>1 2 3 4 5 6 7 8 9 10 11 12 13 14 15</pre></td> <td class="listing_code"><pre class="programlisting"><span class="gtkdoc ppc">#ifdef GDK_WINDOWING_WAYLAND</span> <span class="keyword">if</span> <span class="gtkdoc opt">(</span><span class="function">GDK_IS_WAYLAND_DISPLAY</span> <span class="gtkdoc opt">(</span>display<span class="gtkdoc opt">))</span> <span class="gtkdoc opt">{</span> <span class="gtkdoc slc">// make Wayland-specific calls here</span> <span class="gtkdoc opt">}</span> <span class="keyword">else</span> <span class="gtkdoc ppc">#endif</span> <span class="gtkdoc ppc">#ifdef GDK_WINDOWING_X11</span> <span class="keyword">if</span> <span class="gtkdoc opt">(</span><span class="function">GDK_IS_X11_DISPLAY</span> <span class="gtkdoc opt">(</span>display<span class="gtkdoc opt">))</span> <span class="gtkdoc opt">{</span> <span class="gtkdoc slc">// make X11-specific calls here</span> <span class="gtkdoc opt">}</span> <span class="keyword">else</span> <span class="gtkdoc ppc">#endif</span> <span class="function"><a href="/home/vagrant/ruby-gnome2.win32/glib2/vendor/local/share/gtk-doc/html/glib/glib-Message-Logging.html#g-error">g_error</a></span> <span class="gtkdoc opt">(</span><span class="string">"Unsupported GDK backend"</span><span class="gtkdoc opt">);</span></pre></td> </tr> </tbody> </table> </div> <p></p> </div> <div class="refsect1"> <a name="gdk3-Wayland-Interaction.functions_details"></a><h2>Functions</h2> <p></p> </div> <div class="refsect1"> <a name="gdk3-Wayland-Interaction.other_details"></a><h2>Types and Values</h2> </div> </div> <div class="footer"> <hr>Generated by GTK-Doc V1.25.1</div> </body> </html>
