Best way to QtLabel pixmap draw ROI (region of interest)

I am showing the live video on the QtLabel and detection objects. I want to draw ROI on it to control the are that I want to analyze .
How can I do that rectangle and also change its dimension when needed so I can pass the coordinates to the Opencv to pick the ROI area ?
QRubberBand might be handy for that.
