QWeakPointer:: QWeakPointer (const QObject * obj )

创建 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 .

该函数在 Qt 4.6 引入。
