RadioAction.joinGroup

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

Use this in language bindings instead of the gtk.radio_action.RadioAction.getGroup and gtk.radio_action.RadioAction.setGroup methods

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

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;
    }
