gtk-radio-action-join-group (action source)

action -- a gtk-radio-action object
source -- a gtk-radio-action object whose group we are joining, or nil to remove the radio action from its group

Joins a radio action object to the group of another radio action object. Use this in language bindings instead of the the slot access function gtk-radio-action-group.

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;
  }  

The function gtk-radio-action-join-group has been deprecated since version 3.10 and should not be used in newly written code.
