 * 
 * GdkDisplay objects are the GDK representation of an X Display,

 * a keyboard, a pointing device (such as a mouse) and one or more

 * 
 * Most of the input device handling has been factored out into
 * the separate #GdkDeviceManager object. Every display has a
 * device manager, which you can obtain using
 * gdk_display_get_device_manager().
