I think you are doing a double work here, just use
itemfactory->get_radiomenuitem_widget(path) instead, and that should work as the
above.  Here is how I do it:


 view_opt_ifac->create_item("/Shading", 0, "<LastBranch>", 0);
 view_opt_ifac->create_item("/Shading/Flat", 0, "<RadioItem>",
        ItemFactoryConnector<ViewPort, string>
        (this,
         &change_shade_mode_callback, "SHADE_FLAT"));
 view_opt_ifac->create_item("/Shading/Smooth", 0, "<RadioItem>",
        ItemFactoryConnector<ViewPort, string>
        (this,
         &change_shade_mode_callback, "SHADE_SMOOTH"));

  Gtk_ObjectHandle<Gtk_RadioMenuItem> flat_item =
    view_opt_ifac->get_radiomenuitem_widget("/Shading/Flat");
  Gtk_ObjectHandle<Gtk_RadioMenuItem> smooth_item =
    view_opt_ifac->get_radiomenuitem_widget("/Shading/Smooth");

  smooth_item->set_group(flat_item->group());
  flat_item->set_active(GTK_STATE_ACTIVE);

I just downloaded that chapter and compiled the examples The itemfactory example
suffers from similar problems.  So, I don't think that that is a bug in Gtk--, but
it is either a bug in gtk+ itself, or we are doing something wrong...
