22 * @Title: GtkRecentManager
23 * @short_description: Managing recently used files
24 * @See_Also: #GBookmarkFile, #GtkSettings, #GtkRecentChooser
25 *
26 * #GtkRecentManager provides a facility for adding, removing and
27 * looking up recently used files. Each recently used file is
28 * identified by its URI, and has meta-data associated to it, like
29 * the names and command lines of the applications that have
30 * registered it, the number of time each application has registered
31 * the same file, the mime type of the file and whether the file
32 * should be displayed only by the applications that have
33 * registered it.
34 *
35 * The recently used files list is per user.
36 *
37 * The #GtkRecentManager acts like a database of all the recently
38 * used files. You can create new #GtkRecentManager objects, but
39 * it is more efficient to use the default manager created by GTK+.
40 *
41 * Adding a new recently used file is as simple as:
42 *
43 * |[<!-- language="C" -->
44 * GtkRecentManager *manager;
45 *
46 * manager = gtk_recent_manager_get_default ();
47 * gtk_recent_manager_add_item (manager, file_uri);
48 * ]|
49 *
50 * The #GtkRecentManager will try to gather all the needed information
51 * from the file itself through GIO.
52 *
53 * Looking up the meta-data associated with a recently used file
54 * given its URI requires calling gtk_recent_manager_lookup_item():
55 *
56 * |[<!-- language="C" -->
57 * GtkRecentManager *manager;
58 * GtkRecentInfo *info;
59 * GError *error = NULL;
60 *
61 * manager = gtk_recent_manager_get_default ();
62 * info = gtk_recent_manager_lookup_item (manager, file_uri, &error);
63 * if (error)
64 * {
65 * g_warning ("Could not find the file: %s", error->message);
66 * g_error_free (error);
67 * }
68 * else
69 * {
70 * // Use the info object
71 * gtk_recent_info_unref (info);
72 * }
73 * ]|
74 *
75 * In order to retrieve the list of recently used files, you can use
76 * gtk_recent_manager_get_items(), which returns a list of #GtkRecentInfo-structs.
77 *
78 * A #GtkRecentManager is the model used to populate the contents of
79 * one, or more #GtkRecentChooser implementations.
80 *
81 * Note that the maximum age of the recently used files list is
82 * controllable through the #GtkSettings:gtk-recent-files-max-age
83 * property.
84 *
85 * Recently used files are supported since GTK+ 2.10.
