Detailed Description

QScopedPointer gebruiken voor priv_ptr zodat PIMPL_UNINITIALIZE niet nodig is is niet echt een optie. QScopedPointerDeleter is geimplementeerd met compile-time type checking, wat extra implementatie-constraints oplegt voor de public class. (zie docs voor forward declaration in QScopedPointer)
