Ah... when you edit a cell,  it creates a lineEdit widget which you then
have to set the background on...

Subject: [PyKDE] Qtable Cell Painting Redux

I'm trying to change the background color of a Qtable cell when the user
starts to edit it (and leave it colored to mark as a changed field.

The code below doesn't change the color until another cell if clicked. I've
tried everything (except of course what works).

Anyone see what I'm doing wrong? 

Thanks 

 def cellColor(self, row, col): 
        return self._cellColor.get((row,col), Qt.white) 

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

 def beginEdit(self, row, col, replace):  
        self.setCellColor( row, col, Qt.red) 
        self.repaint() 
        QTable.beginEdit(self, row, col, replace)
