[提问]如何判断一个点（QPoint)是否在某个指定的qwidget里面 [复制链接]

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.

需要重载 qwidget对鼠标事件的操作成员函数吧

如果只需要widget内，QRect：：contains(QPoint())
冲在mousepress时间

如果是很多地方需要，可以自己做一个基类，在widget范围内捕捉touch事件传回指针

试过不行，QTbbWidge只对自己激活的Tab page 有效，所以你右键菜单到inactive tab page. 它始终是拿不到accurate value!! 可能一楼说得时正确的。但是也比较麻烦！
