30.     --  Gtk_Recent_Manager provides a facility for adding, removing and looking up

31.     --  recently used files. Each recently used file is identified by its URI, and

32.     --  has meta-data associated to it, like the names and command lines of the

33.     --  applications that have registered it, the number of time each application

34.     --  has registered the same file, the mime type of the file and whether the

35.     --  file should be displayed only by the applications that have registered it.

36.     --

37.     --  The Gtk_Recent_Manager acts like a database of all the recently used files.

38.     --  You can create new Gtk_Recent_Manager objects, but it is more efficient to

39.     --  use the standard recent manager for the Gdk_Screen so that information

40.     --  about recently used files is shared with other people using them. In case

41.     --  the default screen is being used, adding a new recently used file is

42.     --  as simple as:

43.     --

44.     --     declare

45.     --        Manager : constant Gtk_Recent_Manager := Get_Default;

46.     --     begin

47.     --        Add_Item (Manager, File_URI);

48.     --     end;

49.     --

50.     --  While looking up a recently used file is as simple as using:

51.     --

52.     --     declare

53.     --        Manager : constant Gtk_Recent_Manager := Get_Default;

54.     --        Info    : Gtk_Recent_Info;

55.     --        Error   : Glib.Error.GError;

56.     --     begin

57.     --        Lookup_Item (Info, Manager, File_URI, Error);

58.     --        if Error /= null then

59.     --           --  Use the info object

60.     --           Unref (Info);

61.     --        else

62.     --           Put_Line

63.     --             ("Could not find the file: " & Glib.Error.Get_Message (Error));

64.     --           Glib.Error.Error_Free (Error);

65.     --        end if;

66.     --     end;
