如何判断一个点（QPoint)是否在某个指定的qwidget里面

[weixin_38066328]

Background / pre-condtion :For now, I had implemented a QTabWidget control. meanwhile, I also provide the context operation (mouse right click  menu),and it had run successfully. I append the action ("Remove") into the prior menu and implement the SLOT function for this action.Because QTabWidget has a default item is 0, When I trigger the Context event. How does the QTabWidget know that current index.At here, the only clue is the QPoint pt = QCursor::pos(); If I can verify which widget is I request via pt. The issue should be easy.Pls help me solve this. I will appreciate you!!BTW:  you just implement this method: int IsInWidget(QWidget* pwidget, QPoint pt);           return value means current index of QTabWidget control,            pWidget means specified Widget. pt means specified point coordinate.
