An alternative might be to redo these classes as actual inherited 
subclasses of the Qt counterparts, rather than cut-n-paste rewrites:

class ExtDate : public QDate {
	...
};

That's how many KDE classes with Qt counterparts (KLineEdit, 
KMainWindow, etc) are done.  Definitely more elegant, and it would 
allow for the LGPL.  (Actually, it's an interesting question to ask 
whether KMainWindow constitutes a "derived work" of QMainWindow.  It 
definitelty hooks into the Qt API, and clearly classes like KMainWindow 
would be useless without Qt.  So I guess I don't understand how 
KMainWindow can be LGPL'd, but if they can do it that way, I suppose we 
can too.).

cheers,
Jason
