This doesn't seem entirely correct to me. All classes derived from QWidget
support setLayout() so it would seem possible, at least in principle,
to change the layout of a standard widget. The QWidget docs give an
example of this being done:

http://doc.qtsoftware.com/4.5/qwidget.html#setLayout

I suspect I'm merely doing it incorrectly.

I could do that, but it's a totally different design and much less elegant
than merely deriving from the view widget. I'd be very surprised if it isn't
possible to usefully derive from the standard widgets as I wish.
