Unsolved take a screenshot of arbitrary region of screen.

Hi,
I found that we can take a screenshot by
http://doc.qt.io/qt-5/qtwidgets-desktop-screenshot-example.html
But this example shows how to take a whole desktop screen.
I would like to draw a rectangle on desktop screen and take a screenshot only inside of this screen shot. Is it possible?

I think it's possible.

In the example, it use grabWindow to get the pixmap of screen int shootScreen slot. From the document, you can set a rectangle to specify where you want to grab.
