I have a QWidget which has 2 child QWidget, I want to zoom in it (with its children) by 200% just like we zoom in an image. (as shown in screenshot below)

I know how to zoom in a single QWidget in its paintEvent() via QPainter. But I don't know how to zoom in a QWidget with children.

It looks rather like resizing than zooming. – vahancho Dec 04 '17 at 10:03
Use QtQuick, if your GUI need such zooming – Dmitry Sazonov Dec 04 '17 at 10:59
I cannot use QtQuick since this is a legacy project with new requirement. It's a Qt Designer like app. – ricky Dec 05 '17 at 02:34
