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.

Constructors
|
|
actionGroupNew |
:: 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
|
|
actionGroupGetName |
:: ActionGroup | | -> IO String | returns the name of the action group.
| Gets the name of the action group.
|
|
|
actionGroupGetSensitive :: ActionGroup -> IO Bool |
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.
|
|
actionGroupSetSensitive :: ActionGroup -> Bool -> IO () |
Changes the sensitivity of actionGroup
|
|
actionGroupGetVisible :: ActionGroup -> IO Bool |
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.
|
|
actionGroupSetVisible :: ActionGroup -> Bool -> IO () |
Changes the visible of actionGroup.
|
|
actionGroupGetAction |
:: 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.
|
|
|
actionGroupListActions |
:: 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 () |
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.
|
|
actionGroupAddActionWithAccel |
:: ActionClass action | | => 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 () |
Removes an action object from the action group.
|
|
actionGroupAddActions |
:: 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 "activate" signals of the actions are connected to the callbacks
and their accel paths are set to <Actions>/group-name/action-name.
|
|
|
actionGroupAddToggleActions |
:: 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 "activate" signals of the actions are connected to the callbacks
and their accel paths are set to <Actions>/group-name/action-name.
|
|
|
actionGroupAddRadioActions |
:: 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 "changed" 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.
|
|
|
actionGroupSetTranslateFunc |
|
|
actionGroupSetTranslationDomain |
|
|
actionGroupTranslateString |
:: ActionGroup | | -> String | string - a string
| -> IO String | returns the translation of string
| Translates a string.
- Available since Gtk+ version 2.6
