Qt's Item View delegates the task of painting individual table cells
(in this case, entire rows) to the cleverly-named Delegate classes (
which is basically a funtion object). You get a QPainter object to
paint to, so you can't use QWidgets without massive hacks (which the
Skype people do, and apparently its a horrible horrible thing). Thus
QGraphicsScene.
