The difference is, quite literally, where the reference counter lives. If it's inside the object whose lifetime it controls, then the reference counter cannot outlive the object itself. That means an internal reference counting cannot have QWeakPointer. If the reference count lives outside of the object, then QWeakPointer is possible. Also, for the reference counter to live inside the object, the class needs to have been designed with that in mind. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
