QWeakPointer::QWeakPointer(const QObject *obj)

Creates a QWeakPointer that holds a weak reference directly to the QObject obj. This constructor is only available if the template type T is QObject or derives from it (otherwise a compilation error will result).

You can use this constructor with any QObject, even if they were not created with QSharedPointer.

Note that QWeakPointers created this way on arbitrary QObjects usually cannot be promoted to QSharedPointer.

This function was introduced in Qt 4.6.

See also QSharedPointer and QPointer.
