BTW, while trying to come up with a nice implementation that allowed
setEnable() on actions to enable/disable connected UI elements, I came up
with the following questions/remarks:

1. Is there _any_ way to be notified that a particular menu item has been
deleted from a menu without subclassing the menu from QMenu*? 

2. It's a bit odd that QMenuBar and QPopupMenu don't have a common widget
baseclass. It makes it hard to write generic routines that treat the menus
both as QMenuData objects and QObjects that have an activated(int) signal. 
I had to resort to dynamic_cast so that I wouldn't have to write duplicate
code. Is there a way around this? 

There was a 3. but I'm sleepy and can't remember it. bedtime.
