 * @Short_description: Displays recently used files
 * @Title: GtkRecentChooserWidget
 * @See_also:#GtkRecentChooser, #GtkRecentChooserDialog
 *
 * #GtkRecentChooserWidget is a widget suitable for selecting recently used
 * files.  It is the main building block of a #GtkRecentChooserDialog.  Most
 * applications will only need to use the latter; you can use
 * #GtkRecentChooserWidget as part of a larger window if you have special needs.
 *
 * Note that #GtkRecentChooserWidget does not have any methods of its own.
 * Instead, you should use the functions that work on a #GtkRecentChooser.
 *
 * Recently used files are supported since GTK+ 2.10.
