Description
GtkRecentManager provides a facility for adding, removing and looking up recently used files. Each recently used file is identified by its URI, and has meta-data associated to it, like the names and command lines of the applications that have registered it, the number of time each application has registered the same file, the mime type of the file and whether the file should be displayed only by the applications that have registered it.
The recently used files list is per user.
The GtkRecentManager acts like a database of all the recently used files. You can create new GtkRecentManager objects, but it is more efficient to use the default manager created by GTK+.
Adding a new recently used file is as simple as:
The GtkRecentManager will try to gather all the needed information from the file itself through GIO.
Looking up the meta-data associated with a recently used file given its URI requires calling gtk_recent_manager_lookup_item()
:
GtkRecentManager *manager; manager = gtk_recent_manager_get_default (); gtk_recent_manager_add_item (manager, file_uri);
In order to retrieve the list of recently used files, you can use gtk_recent_manager_get_items()
, which returns a list of GtkRecentInfo-structs.
A GtkRecentManager is the model used to populate the contents of one, or more GtkRecentChooser implementations.
Note that the maximum age of the recently used files list is controllable through the “gtk-recent-files-max-age” property.
Recently used files are supported since GTK+ 2.10.
Functions
gtk_recent_manager_new ()
GtkRecentManager *
gtk_recent_manager_new (void
);
Creates a new recent manager object. Recent manager objects are used to handle the list of recently used resources. A GtkRecentManager object monitors the recently used resources list, and emits the “changed” signal each time something inside the list changes.
GtkRecentManager objects are expensive: be sure to create them only when needed. You should use gtk_recent_manager_get_default()
instead.
Returns
A newly created GtkRecentManager object
Since: 2.10
gtk_recent_manager_get_default ()
GtkRecentManager *
gtk_recent_manager_get_default (void
);
Gets a unique instance of GtkRecentManager, that you can share in your application without caring about memory management.
Since: 2.10
gtk_recent_manager_add_item ()
gboolean gtk_recent_manager_add_item (GtkRecentManager *manager
,const gchar *uri
);
Adds a new resource, pointed by uri
, into the recently used resources list.
This function automatically retrieves some of the needed metadata and setting other metadata to common default values; it then feeds the data to gtk_recent_manager_add_full()
.
See gtk_recent_manager_add_full()
if you want to explicitly define the metadata for the resource pointed by uri
.
Parameters
manager | ||
uri | a valid URI |
Returns
TRUE
if the new item was successfully added to the recently used resources list
Since: 2.10
gtk_recent_manager_add_full ()
gboolean gtk_recent_manager_add_full (GtkRecentManager *manager
,const gchar *uri
,const GtkRecentData *recent_data
);
Adds a new resource, pointed by uri
, into the recently used resources list, using the metadata specified inside the GtkRecentData passed in recent_data
.
The passed URI will be used to identify this resource inside the list.
In order to register the new recently used resource, metadata about the resource must be passed as well as the URI; the metadata is stored in a GtkRecentData, which must contain the MIME type of the resource pointed by the URI; the name of the application that is registering the item, and a command line to be used when launching the item.
Optionally, a GtkRecentData might contain a UTF-8 string to be used when viewing the item instead of the last component of the URI; a short description of the item; whether the item should be considered private - that is, should be displayed only by the applications that have registered it.
Parameters
manager | ||
uri | a valid URI | |
recent_data | metadata of the resource |
Returns
TRUE
if the new item was successfully added to the recently used resources list, FALSE
otherwise

gtk_recent_manager_remove_item ()
gboolean gtk_recent_manager_remove_item (GtkRecentManager *manager

from the recently used resources list handled by a recent manager.
Parameters
manager | ||
uri | the URI of the item you wish to remove | |
error | return location for a GError, or | [allow-none] |
Returns
TRUE
if the item pointed by uri
has been successfully removed by the recently used resources list, and FALSE
otherwise
Since: 2.10
gtk_recent_manager_lookup_item ()
GtkRecentInfo * gtk_recent_manager_lookup_item (GtkRecentManager *manager
,const gchar *uri
,GError **error
);

Parameters
manager | ||

error | a return location for a GError, or | [allow-none] |
Returns
a GtkRecentInfo containing information about the resource pointed by uri
, or NULL
if the URI was not registered in the recently used resources list. Free with gtk_recent_info_unref()
