[Qt-interest] changing the way semected items of a QTableView do appear

Thanks a lot for your hint.
If it can help somebody, this is the paint() code of my custom delegate. It 
paints in white the cells of a QTableView, then it paints the hatch pattern 
defined in my model, and finally it draws the text in the default text 
color.
Is this the right way to do? Indeed, I am not really sure to have understood 
where the dark blue color of a selected item is set: if I comment out the 
line "qpainter.fillRect( rect, qbrush1 )", the dark blue color is still 
here. So if I am right, the dark blue color of a selected item is painted 
BEFORE this paint method of my delegate is called.

This is Python, but this could be understood by any Qt programmer.

Next step: surrounding the selected items of my model with a dotted frame.
