Description
An action of which only one in a group can be active

- radioActionNew :: GlibString string => string -> string -> Maybe string -> Maybe StockId -> Int -> IO RadioAction
- radioActionGetGroup :: RadioActionClass self => self -> IO [RadioAction]
- radioActionSetGroup :: (RadioActionClass self, RadioActionClass groupMember) => self -> groupMember -> IO ()
- radioActionGetCurrentValue :: RadioActionClass self => self -> IO Int

- radioActionCurrentValue :: RadioActionClass self => Attr self Int
- radioActionChanged :: RadioActionClass self => Signal self (RadioAction -> IO ())
Detail
A RadioAction is similar to RadioMenuItem. A number of radio actions
can be linked together so that only one may be active at any one time.

Constructors
Arguments
| :: GlibString string | |
| => string |
|
| -> string |
|
| -> Maybe string |
|
| -> Maybe StockId |
|
| -> Int |
|
| -> IO RadioAction |
Creates a new RadioAction object. To add the action to a ActionGroup
and set the accelerator for the action, call
actionGroupAddActionWithAccel.
Methods
Arguments
| :: RadioActionClass self | |
| => self | |
| -> IO [RadioAction] | returns the members of the radio group |
Returns the list representing the radio group for this object
Arguments
| :: (RadioActionClass self, RadioActionClass groupMember) | |
| => self | |
| -> groupMember |
|
| -> IO () |
Sets the radio group for the radio action object.
radioActionGetCurrentValue Source
Arguments
| :: RadioActionClass self | |
| => self | |
| -> IO Int | returns the value of the currently active group member |
Obtains the value property of the currently active member of the group to which the action belongs.
Attributes
radioActionValueAttr :: RadioActionClass self => Attr self Int Source
The value is an arbitrary integer which can be used as a convenient way
to determine which action in the group is currently active in an ::activate
or ::changed signal handler. See radioActionGetCurrentValue and
RadioActionEntry for convenient ways to get and set
this property.
Default value: 0
radioActionGroup :: RadioActionClass self => ReadWriteAttr self [RadioAction] RadioAction Source
Sets a new group for a radio action.
radioActionCurrentValue :: RadioActionClass self => Attr self Int Source
The value property of the currently active member of the group to which this action belongs.
Default value: 0
- Available since Gtk+ version 2.10
Signals
radioActionChanged :: RadioActionClass self => Signal self (RadioAction -> IO ()) Source
The radioActionChanged signal is emitted on every member of a radio group when the
active member is changed. The signal gets emitted after the actionActivated signals for the
previous and current active members.
