Problem with QGraphicsItem Casting

[D Cell]

I seem to have found the problem. Doing the following works:

QGraphicsItem * item = new SubClass1();
dynamic_cast<Base *>(item);

QGraphicsItem * item = new SubClass1();
dynamic_cast<Base *>(item);

The qgraphicsitem_cast documnetation states:

Note: To make this function work correctly with custom items, reimplement the type() function for each custom QGraphicsItem subclass.

Since I am not casting to the exact type defied by qgraphicsitem::type(), but to my base class instead, it would appear that I need to use a dynamic cast.
