Description

A group of actions

• Module available since Gtk+ version 2.4

Synopsis

# Detail

Actions are organised into groups. An action group is essentially a map from names to Action objects.

All actions that would make sense to use in a particular context should be in a single group. Multiple action groups may be used for a particular user interface. In fact, it is expected that most nontrivial applications will make use of multiple groups. For example, in an application that can edit multiple documents, one group holding global actions (e.g. quit, about, new), and one group per document holding actions that act on that document (eg. save, cut/copy/paste, etc). Each window's menus would be constructed from a combination of two action groups.

Accelerators are handled by the Gtk+ accelerator map. All actions are assigned an accelerator path (which normally has the form <Actions>/group-name/action-name) and a shortcut is associated with this accelerator path. All menuitems and toolitems take on this accelerator path. The Gtk+ accelerator map code makes sure that the correct shortcut is displayed next to the menu item.

A description of an action for an entry that provides a multiple choice.

# Constructors

Arguments

 :: GlibString string => string name - the name of the action group. -> IO ActionGroup

Creates a new ActionGroup object. The name of the action group is used when associating keybindings with the actions.

# Methods

Arguments

 :: GlibString string => ActionGroup -> IO string returns the name of the action group.

Gets the name of the action group.

Returns True if the group is sensitive. The constituent actions can only be logically sensitive (see actionIsSensitive) if they are sensitive (see actionGetSensitive) and their group is sensitive.

Changes the sensitivity of actionGroup

Returns True if the group is visible. The constituent actions can only be logically visible (see actionIsVisible) if they are visible (see actionGetVisible) and their group is visible.

Changes the visible of actionGroup.

Arguments

 :: GlibString string => ActionGroup -> string actionName - the name of the action -> IO (Maybe Action) returns the action, or Nothing if no action by that name exists

Looks up an action in the action group by name.

Arguments

 :: ActionGroup -> IO [Action] returns a list of the action objects in the action group

Lists the actions in the action group.

actionGroupAddAction :: ActionClass action => ActionGroup -> action -> IO () Source #

Adds an action object to the action group. Note that this function does not set up the accel path of the action, which can lead to problems if a user tries to modify the accelerator of a menuitem associated with the action. Therefore you must either set the accel path yourself with actionSetAccelPath, or use actionGroupAddActionWithAccel ... Nothing.

Arguments

 :: (ActionClass action, GlibString string) => ActionGroup -> action action - the action to add -> Maybe string accelerator - the accelerator for the action, in the format understood by acceleratorParse, or "" for no accelerator, or Nothing to use the stock accelerator -> IO ()

Adds an action object to the action group and sets up the accelerator.

If accelerator is Nothing, attempts to use the accelerator associated with the stock id of the action.

Accel paths are set to <Actions>/group-name/action-name.

actionGroupRemoveAction :: ActionClass action => ActionGroup -> action -> IO () Source #

Removes an action object from the action group.

Arguments

 :: ActionGroup -> [ActionEntry] entries - a list of action descriptions -> IO ()

This is a convenience function to create a number of actions and add them to the action group.

The actionActivated signals of the actions are connected to the callbacks and their accel paths are set to <Actions>/group-name/action-name.

Arguments

 :: ActionGroup -> [ToggleActionEntry] entries - a list of toggle action descriptions -> IO ()

This is a convenience function to create a number of toggle actions and add them to the action group.

The actionActivated signals of the actions are connected to the callbacks and their accel paths are set to <Actions>/group-name/action-name.

Arguments

 :: ActionGroup -> [RadioActionEntry] entries - a list of radio action descriptions -> Int value - the value of the action to activate initially, or -1 if no action should be activated -> (RadioAction -> IO ()) onChange - the callback for the changed signal -> IO ()

This is a convenience routine to create a group of radio actions and add them to the action group.

The radioActionChanged signal of the first radio action is connected to the onChange callback and the accel paths of the actions are set to <Actions>/group-name/action-name.

Arguments

 :: GlibString string => ActionGroup -> (string -> IO string) (label -> ...) - a translation function -> IO ()

Sets a function to be used for translating the label and tooltip of ActionEntrys added by actionGroupAddActions.

If you're using 'gettext', it is enough to set the translation domain with actionGroupSetTranslationDomain.

Arguments

 :: GlibString string => ActionGroup -> string domain - the translation domain to use for 'dgettext' calls -> IO ()

Sets the translation domain and uses 'dgettext' for translating the label and tooltip of ActionEntrys added by actionGroupAddActions.

If you're not using 'gettext' for localization, see actionGroupSetTranslateFunc.

Arguments

 :: GlibString string => ActionGroup -> string string - a string -> IO string returns the translation of string

Translates a string.

• Available since Gtk+ version 2.6
