Struct gtk4::RecentManager [−][src]
pub struct RecentManager(_);Expand description
RecentManager manages and looks 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.
RecentManager acts like a database of all the recently
used files. You can create new RecentManager 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 following code is in c ⚠️
GtkRecentManager *manager;
manager = gtk_recent_manager_get_default ();
gtk_recent_manager_add_item (manager, file_uri);The RecentManager 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 RecentManagerExt::lookup_item():
⚠️ The following code is in c ⚠️
GtkRecentManager *manager;
GtkRecentInfo *info;
GError *error = NULL;
manager = gtk_recent_manager_get_default ();
info = gtk_recent_manager_lookup_item (manager, file_uri, &error);
if (error)
{
g_warning ("Could not find the file: %s", error->message);
g_error_free (error);
}
else
{
// Use the info object
gtk_recent_info_unref (info);
}In order to retrieve the list of recently used files, you can use
RecentManagerExt::items(), which returns a list of
RecentInfo.
Note that the maximum age of the recently used files list is
controllable through the property::Settings::gtk-recent-files-max-age
property.
Implements
Implementations
Creates a new recent manager object.
Recent manager objects are used to handle the list of recently used
resources. A RecentManager object monitors the recently used
resources list, and emits the signal::RecentManager::changed
signal each time something inside the list changes.
RecentManager objects are expensive: be sure to create them
only when needed. You should use default()
instead.
Returns
A newly created RecentManager object
Gets a unique instance of RecentManager that you can share
in your application without caring about memory management.
Returns
A unique RecentManager. Do not ref or
unref it.
