Hi Rob, I think you got me a little bit wrong: I don't want the menu to handle the logic. I can handle the logic my self. But I need to tell the menu that it should show (paint) a menu item as disabled.
Give me a method like this and I am happy: MenuItem.setEnabled (boolean enabled); Well, the recommendation for gwtlib from Alan shows that this must be implemented already. Then it must also be possible for me to do this "by hand", without using an additional library. But how? It would be fine if someone could tell how this can be done.
