I have a proof-of-concept branch up showing one way of eliminating the explicit casts from QWidget in tabs_manager. It works by writing an explicit interface describing what the manager needs from its associated widget, with protections assigned so that only the manager can invoke the methods. To the other widgets, this object is just an opaque reference that they pass along to the manager.
The branch tabs-manager-eliminate-casts-qt in my personal git repository (SHA c32f42b) has the patches. I also created a branch tabs-manager-eliminate-casts-sigc (SHA b9dc49b) with a sigc++-based implementation. I think this is a lot cleaner (there are some kind of ugly things in the Qt implementation), but it doesn't fit into the Qt idioms in src/qt/.
