QColorGroup does no such magic, it's only a container for colors :)

What you want is usually something like
    QPainter p( viewport() );
    p.translate( -contentsX(), -contentsY() );
    p.setBrushOrigin( -contentsX(), -contentsY() );

(Well, maybe only the last line in the case of paintCell()).
