You cannot have common model for QTreeView and QGraphicsView, even though both of these are based on same concepts (Model/View), but the these use a different set of model interface classes.

What you can do is, have a QTreeView connected to a QAbstractItemModel, and a QGraphicsView connected to QGraphicsScene, and then connect the QAbstractItemModel to QGraphicsView in the back-end. (You might have already figured this out, by now)

The connection between QAbstractItemModel and QGraphicsView is responsible in keeping then in sync, so using signals & slot mechanism should be good, rather than a interface class.

Also needless to mention you need use sub-class ofQAbstractItemMoel and sub-class of QGraphicsScen, as these base classes will not be sufficient to support the syncing functions
