I told you that programming in python is just fun, and - # suddently, you have to care about things you don't even know. - # - # but calm down, the solution is easy, at least on paper: - # - # Each Component, which is a GUIComponent, owns references to each - # instantiated eWidget (namely in screen.data[name]["instance"], in case - # you care.) - # on deleteGUIscreen, all eWidget *must* (!) be deleted (otherwise, - # well, problems appear.
