/**
* SECTION:gdkdisplaymanager
* The purpose of the #GdkDisplayManager singleton object is to offer
* notification when displays appear or disappear or the default display
* changes.
+ *
+ * You can use gdk_display_manager_get() to obtain the GdkDisplayManager
+ * singleton, but that should be rarely necessary. Typically, initializing
+ * GTK+ opens a display that you can work with without ever accessing the
+ * GdkDisplayManager.
+ *
+ * The GDK library can be built with support for multiple backends.
+ * The GdkDisplayManager object determines which backend is used
+ * at runtime.
+ *
+ * When writing backend-specific code that is supposed to work with
+ * multiple GDK backends, you have to consider both compile time and
+ * runtime. At compile time, use the #GDK_WINDOWING_X11, #GDK_WINDOWING_WIN32
+ * macros, etc. to find out which backends are present in the GDK library
+ * you are building your application against. At runtime, use type-check
+ * macros like GDK_IS_X11_DISPLAY() to find out which backend is in use:
+ *
+ * <example id="backend-specific">
+ * <title>Backend-specific code</title>
+ * <programlisting>
+ * #ifdef GDK_WINDOWING_X11
+ * if (GDK_IS_X11_DISPLAY (display))
+ * {
+ * /* make X11-specific calls here */
+ * }
+ * else
+ * #endif
+ * #ifdef GDK_WINDOWING_QUARTZ
+ * if (GDK_IS_QUARTZ_DISPLAY (display))
+ * {
+ * /* make Quartz-specific calls here */
+* }
+ * else
+ * #endif
+ * g_error ("Unsupported GDK backend");
+ * </programlisting>
+ * </example>
