RadioAction.getGroup

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:

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);
}
