QCommonStyle is a possibility.  I'll have to see what I lose from 
QWindowStyle and whether I can add anything missing to my derived class.

I'm just using this to deal with something in a derived QFileDialog.  We 
need to set the column headers manually depending on language. One of 
the Trolltech guys gave us a sample to do that a few years ago and it's 
using the subclassed style. A quick test in Qt4 looks like QCommonStyle 
will probably be acceptable.
