* @Short_description: An action of which represents a list of recently used files
* @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.
