GI.Gtk.Objects.RadioAction

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.

Methods

Overloaded methods

getCurrentValue

radioActionGetCurrentValue

Arguments

:: (HasCallStack, MonadIO m, IsRadioAction a)

=> a

action: a RadioAction

-> m Int32

Returns: The value of the currently active group member

Deprecated: (Since version 3.10)

Obtains the value property of the currently active member of the group to which action belongs.

Since: 2.4

getGroup

radioActionGetGroup

Arguments

:: (HasCallStack, MonadIO m, IsRadioAction a)

=> a

action: the action object

-> m [RadioAction]

Returns: the list representing the radio group for this object

Deprecated: (Since version 3.10)

Returns the list representing the radio group for this object. Note that the returned list is only valid until the next change to the group.

A common way to set up a group of radio group is the following:

C code

 GSList *group = NULL;
 GtkRadioAction *action;

 while ( ...more actions to add... /)
   {
      action = gtk_radio_action_new (...);
      
      gtk_radio_action_set_group (action, group);
      group = gtk_radio_action_get_group (action);
   }

Since: 2.4

joinGroup

radioActionJoinGroup

Arguments

:: (HasCallStack, MonadIO m, IsRadioAction a, IsRadioAction b)

=> a

action: the action object

-> Maybe b

groupSource: a radio action object whos group we are joining, or Nothing to remove the radio action from its group

-> m ()

Deprecated: (Since version 3.10)

Joins a radio action object to the group of another radio action object.

Use this in language bindings instead of the radioActionGetGroup and radioActionSetGroup methods

A common way to set up a group of radio actions is the following:

C code

 GtkRadioAction *action;
 GtkRadioAction *last_action;

 while ( ...more actions to add... /)
   {
      action = gtk_radio_action_new (...);
      
      gtk_radio_action_join_group (action, last_action);
      last_action = action;
   }

Since: 3.0

new

radioActionNew

Arguments

:: (HasCallStack, MonadIO m)

=> Text

name: A unique name for the action

-> Maybe Text

label: The label displayed in menu items and on buttons, or Nothing

-> Maybe Text

tooltip: A tooltip for this action, or Nothing

-> Maybe Text

stockId: The stock icon to display in widgets representing this action, or Nothing

-> Int32

value: The value which radioActionGetCurrentValue should return if this action is selected.

-> m RadioAction

Returns: a new RadioAction

Deprecated: (Since version 3.10)

Creates a new RadioAction object. To add the action to a ActionGroup and set the accelerator for the action, call actionGroupAddActionWithAccel.

Since: 2.4

setCurrentValue

radioActionSetCurrentValue

Arguments

:: (HasCallStack, MonadIO m, IsRadioAction a)

=> a

action: a RadioAction

-> Int32

currentValue: the new value

-> m ()

Deprecated: (Since version 3.10)

Sets the currently active group member to the member with value property currentValue.

Since: 2.10

setGroup

radioActionSetGroup

Arguments

:: (HasCallStack, MonadIO m, IsRadioAction a, IsRadioAction b)

=> a

action: the action object

-> [b]

group: a list representing a radio group, or Nothing

-> m ()

Deprecated: (Since version 3.10)

Sets the radio group for the radio action object.

Since: 2.4

Properties

currentValue

The value property of the currently active member of the group to which this action belongs.

Since: 2.10

constructRadioActionCurrentValue :: (IsRadioAction o, MonadIO m) => Int32 -> m (GValueConstruct o)

Construct a GValueConstruct with valid value for the “current-value” property. This is rarely needed directly, but it is used by new.

getRadioActionCurrentValue :: (MonadIO m, IsRadioAction o) => o -> m Int32

Get the value of the “current-value” property. When overloading is enabled, this is equivalent to

get radioAction #currentValue

setRadioActionCurrentValue :: (MonadIO m, IsRadioAction o) => o -> Int32 -> m ()

Set the value of the “current-value” property. When overloading is enabled, this is equivalent to

set radioAction [ #currentValue := value ]

group

Sets a new group for a radio action.

Since: 2.4

clearRadioActionGroup :: (MonadIO m, IsRadioAction o) => o -> m ()

Set the value of the “group” property to Nothing. When overloading is enabled, this is equivalent to

clear #group

constructRadioActionGroup :: (IsRadioAction o, MonadIO m, IsRadioAction a) => a -> m (GValueConstruct o)

Construct a GValueConstruct with valid value for the “group” property. This is rarely needed directly, but it is used by new.

setRadioActionGroup :: (MonadIO m, IsRadioAction o, IsRadioAction a) => o -> a -> m ()

Set the value of the “group” property. When overloading is enabled, this is equivalent to

set radioAction [ #group := value ]

value

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.

Since: 2.4

constructRadioActionValue :: (IsRadioAction o, MonadIO m) => Int32 -> m (GValueConstruct o)

Construct a GValueConstruct with valid value for the “value” property. This is rarely needed directly, but it is used by new.

getRadioActionValue :: (MonadIO m, IsRadioAction o) => o -> m Int32

Get the value of the “value” property. When overloading is enabled, this is equivalent to

get radioAction #value

setRadioActionValue :: (MonadIO m, IsRadioAction o) => o -> Int32 -> m ()

Set the value of the “value” property. When overloading is enabled, this is equivalent to

set radioAction [ #value := value ]

Signals

changed

type C_RadioActionChangedCallback = Ptr () -> Ptr RadioAction -> Ptr () -> IO ()

Type for the callback on the (unwrapped) C side.

type RadioActionChangedCallback

Arguments

 = RadioAction

current: the member of action's group which has just been activated

-> IO ()

Deprecated: (Since version 3.10)

The changed signal is emitted on every member of a radio group when the active member is changed. The signal gets emitted after the activate signals for the previous and current active members.

Since: 2.4

afterRadioActionChanged :: (IsRadioAction a, MonadIO m) => a -> RadioActionChangedCallback -> m SignalHandlerId

Connect a signal handler for the changed signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after radioAction #changed callback

genClosure_RadioActionChanged :: MonadIO m => RadioActionChangedCallback -> m (GClosure C_RadioActionChangedCallback)

Wrap the callback into a GClosure.

mk_RadioActionChangedCallback :: C_RadioActionChangedCallback -> IO (FunPtr C_RadioActionChangedCallback)

Generate a function pointer callable from C code, from a C_RadioActionChangedCallback.

noRadioActionChangedCallback :: Maybe RadioActionChangedCallback

A convenience synonym for Nothing :: Maybe RadioActionChangedCallback.

onRadioActionChanged :: (IsRadioAction a, MonadIO m) => a -> RadioActionChangedCallback -> m SignalHandlerId

Connect a signal handler for the changed signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on radioAction #changed callback

wrap_RadioActionChangedCallback :: RadioActionChangedCallback -> C_RadioActionChangedCallback

Wrap a RadioActionChangedCallback into a C_RadioActionChangedCallback.
