I was talking about the _geom QRect. I would hope that a QRegion
that is really just a QRect would be very close in performance
as the native QRect (assuming Qt wrote the code in a clever way).

The only problem I'm aware of the line/arrow problem in Kst with
my previous fix (now reverted) was that you can hover over parts
of the arrow and not set the focus. This is because the findChild
and findDeepestChild use the _geom to detect the focus. Is there
any reason that they don't use the clip region, in which case this
problem goes away?

  Which QRect?  QRegion is quite expensive btw.  I tried to avoid it
whenever
possible.
