Keeps a pointer to a QObject and deletes it whenever this object is deleted.
It keeps a weak pointer to the QObject internally and will be set to nullptr
whenever the QObject is deleted.

If there is already a QObject managed currently it will be deleted. If p
is not specified the managed QObject will be deleted and this object reset to nullptr
.
