Package: Recent_Manager

Description

package Gtk.Recent_Manager is

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

You can create new Gtk_Recent_Manager objects, but it is more efficient to use the standard recent manager for the Gdk_Screen so that information about recently used files is shared with other people using them. In case the default screen is being used, adding a new recently used file is as simple as: declare Manager : constant Gtk_Recent_Manager := Get_Default; begin Add_Item (Manager, File_URI); end; While looking up a recently used file is as simple as using: declare Manager : constant Gtk_Recent_Manager := Get_Default; Info : Gtk_Recent_Info; Error : Glib.Error.GError; begin Lookup_Item (Info, Manager, File_URI, Error); if Error /= null then -- Use the info object Unref (Info); else Put_Line ("Could not find the file: " & Glib.Error.Get_Message (Error)); Glib.Error.Error_Free (Error); end if; end; Recently used files are supported since GTK+ 2.10.

Binding from C File version 2.16.6

Initialize

procedure Initialize 
(Widget: access Gtk_Recent_Manager_Record'Class);
Creates a new recent manager object. Recent manager objects are used to handle the list of recently used resources. A Gtk_Recent_Manager object monitors the recently used resources list, and emits the "changed" signal each time something inside the list changes. Gtk_Recent_Manager objects are expensive: be sure to create them only when needed. You should use Gtk.Recent_Manager.Get_Default instead.

Get_Type

function Get_Type return GType;
Return the internal value associated with a Gtk_Recent_Manager widget.

Error_Quark

function Error_Quark return GQuark;

Add_Full

function Add_Full 
(Manager: access Gtk_Recent_Manager_Record;
Uri: UTF8_String;
Display_Name: UTF8_String := "";
Description: UTF8_String := "";
Mime_Type: UTF8_String;
App_Name: UTF8_String;
App_Exec: UTF8_String;
Groups: GNAT.Strings.String_List;
Is_Private: Boolean) return Boolean;
Manager : the Gtk_Recent_Manager on which to operate Uri : pointer to resource Display_Name : a UTF-8 encoded string, containing the name of the recently used resource to be displayed, or "". Description : a UTF-8 encoded string, containing a short description of the resource, or "". Mime_Type : the MIME type of the resource. App_Name : the name of the application that is registering this recently used resource. App_Exec : command line used to launch this resource; may contain the "%f" and "%u" escape characters which will be expanded to the resource file path and URI, respectively, when the command line is retrieved. Groups : a vector of strings containing groups names. Is_Private : whether this resource should be displayed only by the applications that have registered it or not. Adds a new resource, pointed by Uri, into the recently used resources list, using the metadata specified. 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. This metadata 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, it is possible to specify 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. Returns True if the new item was successfully added to the recently used resources list, False otherwise.

Add_Item

function Add_Item 
(Manager: access Gtk_Recent_Manager_Record;
Uri: UTF8_String) return Boolean;
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 Add_Full. See Add_Full if you want to explicitly define the metadata for the resource pointed by Uri. Returns True if the new item was successfully added to the recently used resources list

Get_Default

function Get_Default return Gtk_Recent_Manager;
Gets a unique instance of Gtk_Recent_Manager that you can share in your application without caring about memory management. The returned instance will be freed when you application terminates. Do not ref or unref the returned manager.

Get_Items

function Get_Items 
(Manager: access Gtk_Recent_Manager_Record) return Gtk_Recent_Info_List.Glist;
Gets the list of recently used resources. Use Unref on each item inside the list, and then free the list itself using Glib.Object.Object_Simple_List.Free.

Get_Limit

function Get_Limit 
(Manager: access Gtk_Recent_Manager_Record) return Gint;

Set_Limit

procedure Set_Limit 
(Manager: access Gtk_Recent_Manager_Record;
Limit: Gint);
Maximum number of items that the Get_Items function should return. If Limit is set to -1, then return all the items.

Has_Item

function Has_Item 
(Manager: access Gtk_Recent_Manager_Record;
Uri: UTF8_String) return Boolean;
Checks whether there is a recently used resource registered with Uri inside the recent manager.

Lookup_Item

function Lookup_Item 
(Manager: access Gtk_Recent_Manager_Record;
Uri: UTF8_String;
Error: Glib.Error.GError) return Gtk_Recent_Info;
Searches for a URI inside the recently used resources list, and returns a structure containing information about the resource like its MIME type, or its display name. Returns null if the URI was not registered in the recently used resources list. Free with Unref.

Move_Item

function Move_Item 
(Manager: access Gtk_Recent_Manager_Record;
Uri: UTF8_String;
New_Uri: UTF8_String;
Error: Glib.Error.GError) return Boolean;
Changes the location of a recently used resource from Uri to New_Uri. A New_Uri of "" will remove the item pointed to by Uri in the list. Please note that this function will not affect the resource pointed by the URIs, but only the URI used in the recently used resources list.

Purge_Items

function Purge_Items 
(Manager: access Gtk_Recent_Manager_Record;
Error: Glib.Error.GError) return Gint;
Purges every item from the recently used resources list. Returns the number of items that have been removed from the recently used resources list.

Remove_Item

function Remove_Item 
(Manager: access Gtk_Recent_Manager_Record;
Uri: UTF8_String;
Error: Glib.Error.GError) return Boolean;
Removes a resource pointed by Uri from the recently used resources list handled by a recent manager.

Get_For_Screen

function Get_For_Screen 
(Screen: access Gdk.Screen.Gdk_Screen_Record) return Gtk_Recent_Manager;
Get_For_Screen Gets the recent manager object associated with Screen; if this function has not previously been called for the given screen, a new recent manager object will be created and associated with the screen. Recent manager objects are fairly expensive to create, so using this function is usually a better choice than calling New and setting the screen yourself; by using this function a single recent manager object will be shared between users. Return value: A unique Gtk_Recent_Manager associated with the given screen. This recent manager is associated to the with the screen and can be used as long as the screen is open. Do not ref or unref it. Deprecated: 2.12: This function has been deprecated and should not be used in newly written code. Calling this function is equivalent to calling Get_Default.

Set_Screen

procedure Set_Screen 
(Manager: access Gtk_Recent_Manager_Record;
Screen: access Gdk.Screen.Gdk_Screen_Record'Class);
Set_Screen Sets the screen for a recent manager; the screen is used to track the user's currently configured recently used documents storage. Deprecated: 2.12: This function has been deprecated and should not be used in newly written code. Calling this function has no effect.
