Memory-managed wrapper type.

Type class for types which can be safely cast to RadioAction, for instance with toRadioAction.

Cast to RadioAction, for types for which this is known to be safe. For general casts, use castTo.

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

Since: 2.4

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

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

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

Since: 2.4

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

Since: 2.10

Sets the radio group for the radio action object.

Since: 2.4

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

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

get radioAction #currentValue

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

set radioAction [ #currentValue := value ]

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

clear #group

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

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

set radioAction [ #group := value ]

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

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

get radioAction #value

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

set radioAction [ #value := value ]

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

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

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

Wrap the callback into a GClosure.

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

A convenience synonym for Nothing :: Maybe RadioActionChangedCallback.

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 a RadioActionChangedCallback into a C_RadioActionChangedCallback.
