[Interest] How to disable multi touch for iOS

I am using Qt (not QtQuick) to develop an iOS app. I have been trying to
find a way to disable multitouch in the widget so that no 2 widgets can
receive touchEvent/mousePressEvent at the same time.

I have tried setting *UIView.multipleTouchEnabled = false * but I am no
longer getting QGestureEvent. I believe this is because Qt's gesture is
depending on the multiTouch
I have also tried setting *UIView.exclusiveTouch = true *however this only
works for native widget or windows within a same level parent. So if I have
a Native widget and a QPushButton within a window, I have no way to set the
flag to QPushButton.

Is there any way to achieve what I am looking for?

Thanks in advance for your help.
