Have you ever used widgets in Interview? I don't think its possible easily. I've talked to a developer who has done it and he told me quite clearly that it has sucked his life. QAbstractItemView::setIndexWidget says: "This function should only be used to display static content within the visible area corresponding to an item of data. If you want to display custom dynamic content or implement a custom editor widget, subclass QItemDelegate instead."

I'm using QGraphicsScene::render to paint on QAbstractItemDelegate::paint calls.

The delegate update would be too hard to do.
But how would you do it? :)

Really just ignore that I'm using a delegate, or a QGraphicsScene or whatever. I'm certainly open to other ways of doing it.

I simply don't see how to ever put animations in a QAbstractListView.
