Re: [PyKDE] Error when overloading QTable.paintCell

You wrote, that one should use a construct like in such a case:

    def paintCell(self, p, row, col, cr, selected, cg = None):
        if cg:
            myc = QColorGroup(cg)
            myc.setColor(QColorGroup.Text, self.cellColor(row, col))
            QTable.paintCell(self, p, row, col, cr, selected, myc)
        else:
            QTable.paintCell(self, p, row, col, cr, selected)

Hmpf, Qt seems to calls this method 2 times for every cell. 

Thanks god, the second is the right one (with cg). 

Thanks for the tip.

Have a good night,
