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