23 * @Title: GtkRecentManager
24 * @short_description: Managing recently used files
25 * @See_Also: #GBookmarkFile, #GtkSettings, #GtkRecentChooser
27 * #GtkRecentManager provides a facility for adding, removing and
28 * looking up recently used files. Each recently used file is
29 * identified by its URI, and has meta-data associated to it, like
30 * the names and command lines of the applications that have
31 * registered it, the number of time each application has registered
32 * the same file, the mime type of the file and whether the file
33 * should be displayed only by the applications that have
36 * <note><para>The recently used files list is per user.</para></note>
38 * The #GtkRecentManager acts like a database of all the recently
39 * used files. You can create new #GtkRecentManager objects, but
40 * it is more efficient to use the default manager created by GTK+.
42 * Adding a new recently used file is as simple as:
45 * GtkRecentManager *manager;
47 * manager = gtk_recent_manager_get_default ();
48 * gtk_recent_manager_add_item (manager, file_uri);
51 * The #GtkRecentManager will try to gather all the needed information
52 * from the file itself through GIO.
54 * Looking up the meta-data associated with a recently used file
55 * given its URI requires calling gtk_recent_manager_lookup_item():
58 * GtkRecentManager *manager;
59 * GtkRecentInfo *info;
60 * GError *error = NULL;
62 * manager = gtk_recent_manager_get_default ();
63 * info = gtk_recent_manager_lookup_item (manager, file_uri, &error);
66 * g_warning ("Could not find the file: %s", error->message);
67 * g_error_free (error);
71 * /* Use the info object */
72 * gtk_recent_info_unref (info);
76 * In order to retrieve the list of recently used files, you can use
77 * gtk_recent_manager_get_items(), which returns a list of #GtkRecentInfo
80 * A #GtkRecentManager is the model used to populate the contents of
81 * one, or more #GtkRecentChooser implementations.
83 * <note><para>The maximum age of the recently used files list is
84 * controllable through the #GtkSettings:gtk-recent-files-max-age
85 * property.</para></note>
87 * Recently used files are supported since GTK+ 2.10.
