 * @Title: GtkRecentAction
 *
 * A #GtkRecentAction represents a list of recently used files, which
 * can be shown by widgets such as #GtkRecentChooserDialog or
 * #GtkRecentChooserMenu.
 *
 * To construct a submenu showing recently used files, use a #GtkRecentAction
 * as the action for a &lt;menuitem&gt;. To construct a menu toolbutton showing
 * the recently used files in the popup menu, use a #GtkRecentAction as the
 * action for a &lt;toolitem&gt; element.
