QPointer is a strange "smart" pointer class, which resets itself when the pointed-to QObject is deleted. It does this by listening to the corresponding signal and therefore is surprisingly heavy for a plain pointer. A cynic would say that the existence of QPointer is an expression of Qt's broken ownership model. In any case, QPointer was only used at two places, were it was 100% useless: As a parameter to a function and as a locally scoped pointer. It only makes sense if a) there is a chance that the object disappears during the pointer's lifetime and b) it is actually checked for null before use None of which was the case here. Remove.
