So in Qt5 QPointer is again the preferred way of tracking QObjects. Using QWeakPointer now will just add a porting step that would otherwise not be required.

Not even that, this was "fixed" in Qt 4.6 already, see the link I posted below: http://www.macieira.org/blog/2012/07/continue-using-qpointer/
