Thats mostly for normal QWidget subclasses, the interview classes have dnd support builtin, based on what the model provides. The puzzle example demonstrates this pretty well, you have a listview and a normal qwidget and both have drag and drop capabilities. There's only a subclass for the QWidget, the listview stays "standard" - only the model has proper overrides for the drag/drop methods needed.
