47 * @Short_description: Displays recently used files in a menu
48 * @Title: GtkRecentChooserMenu
49 * @See_also:#GtkRecentChooser
50 *
51 * #GtkRecentChooserMenu is a widget suitable for displaying recently used files
52 * inside a menu. It can be used to set a sub-menu of a #GtkMenuItem using
53 * gtk_menu_item_set_submenu(), or as the menu of a #GtkMenuToolButton.
54 *
55 * Note that #GtkRecentChooserMenu does not have any methods of its own. Instead,
56 * you should use the functions that work on a #GtkRecentChooser.
57 *
58 * Note also that #GtkRecentChooserMenu does not support multiple filters, as it
59 * has no way to let the user choose between them as the #GtkRecentChooserWidget
60 * and #GtkRecentChooserDialog widgets do. Thus using gtk_recent_chooser_add_filter()
61 * on a #GtkRecentChooserMenu widget will yield the same effects as using
62 * gtk_recent_chooser_set_filter(), replacing any currently set filter
63 * with the supplied filter; gtk_recent_chooser_remove_filter() will remove
64 * any currently set #GtkRecentFilter object and will unset the current filter;
65 * gtk_recent_chooser_list_filters() will return a list containing a single
66 * #GtkRecentFilter object.
67 *
68 * Recently used files are supported since GTK+ 2.10.
