That's what i meant, this new instance is in no way connacted to the widget, 
so we are drawing somewhere in memory but it never gets displayed (i think).

There is still the problem now that it is not really the widget that gets 
painted but its parent window.
So i tried:
unset_flags(Gtk::NO_WINDOW);
set_window( Gdk::Window::create(get_window() /* parent */, &attributes, 
GDK_WA_X | GDK_WA_Y) );
m_refGdkWindow = get_window();

It works but now the widget doesn't receive an expose event anymore.
