[Interest] setting a widget style for a particular widget class only?

[Andy]

Thanks Lorenz.

My comment was actually about the call to QStyleFactory::create().  I
wasn't sure if QStyleFactory created it and kept track of it somewhere
(only load a style once?) or if I needed to manage it myself.  Usually when
I write these kinds of methods (static methods on classes which create
things) I like to document who owns the resulting pointer so there's no
question who's going to manage the memory.
