No, calling gtk_widget_destroy() will probably always lead to disaster.

If you want to delete your widgets, or any other object, then use the C
++ keyword "delete".


...which means that the documentation that Maik brought up at the
beginning of this thread should really be changed so that it doesn't
mention anything about Gtk::Widget::Destroy() (which doesn't exist)
but instead tell people to 'delete' the widget in the normal C++ way.
