Как setTransformOriginPoint из QGraphicsRectItem для вращения и смещения

Question

Я не нашел ответа, поэтому хотел бы спросить, как установить исходную точку для вращения. Например, я установил исходную точку для вращения на [200,200], и я хотел бы сохранить исходную точку для вращения до и после смещения. Я попробовал setTransformOriginPoint, но он не работает и по-прежнему принимает [0,0] в качестве исходной точки для вращения. Спасибо.
