Best way to cast QList of base class pointers to derived class pointers

[wayfaerer]

I have a QList of base class pointers:

QList<QGraphicsItem*> selectedItems = myGraphicsScene->selectedItems();

QList<QGraphicsItem*> selectedItems = myGraphicsScene->selectedItems();

To copy to clipboard, switch view to plain text mode 

but I'd like it to be a derived class, e.g., QList<DerivedGraphicsItem*>. Is there any way to do this other than iterating through the list and creating a new one?

Note that in this particular case, I want to static cast, although I'm curious how it would work to dynamic cast in this situation too.
