Much easier is to override paintCell of QTable.
def paintCell ( self, p, row, col, cr, selected):
self.verticalHeader().setLabel(row, str(row *2))
QTable.paintCell ( self, p, row, col, cr, selected, self.colorGroup())
The header will now be painted on demand....
My experience with PyQT is to pull the data from your data structures. Works
much faster than iterating over objects.
