[PySide] inherited values that contribute to widgets position

[Frank Rueter | OHUfx]

Hi Srini,

thanks for the details but I'm not using QGraphicsView.
This is a custom Widget with a stacked layout, that slides the old 
widgets out of frame and the new ones in.
I'm thinking something like this might be what I need to collect and add 
to the widgets' position to get their true positional values (so the 
animation won't stutter):
self.style().pixelMetric( QStyle.PM_DefaultFrameWidth )
