RadioMenuItem.joinGroup

Joins a #GtkRadioMenuItem object to the group of another #GtkRadioMenuItem object.

This function should be used by language bindings to avoid the memory manangement of the opaque #GSList of [gtk.radio_menu_item.RadioMenuItem.getGroup] and [gtk.radio_menu_item.RadioMenuItem.setGroup].

A common way to set up a group of #GtkRadioMenuItem instances is:

GtkRadioMenuItem *last_item = NULL;

 while ( ...more items to add... )
   {
     GtkRadioMenuItem *radio_item;

     radio_item = gtk_radio_menu_item_new (...);

     gtk_radio_menu_item_join_group (radio_item, last_item);
     last_item = radio_item;
   }
