	QVariantPointer (const Pointer * pointer )
QVariantRef<Pointer>	operator* () const
Pointer	operator-> () const

詳細描述

QVariantConstPointer wraps a pointer and returns QVariantRef to it from its operator*(). This makes it suitable as replacement for an actual pointer. We cannot return an actual pointer from generic iterators as the iterators don't hold an actual QVariant .
