There is an almost opposite approach too, which can work sometimes.

	Gtk::Widget* genericVersionOfSpecialWidget = 
                   Glib::wrap (gtk_special_widget_new());

         .... do stuff with the generic Gtk::Widget* ....
         .... such as packing it into containers etc ....

then when you need something other than the generic Widget API:

        GtkSpecialWidget* specialWidget = (GTK_SPECIAL_WIDGET*)
          (genericVersionOfSpecialWidget->gobj());

        gtk_special_widget_do_something_special (specialWidget);
