How to display a MDI subwindow in front of a QGraphgicsView view ?

[wisconxing]

I have a mainwindow with a QGraphicsView view, I want to click menu File\New to display a Mdi subwindow. But the Mdi subwindow is always behind the view. How to display a MDI subwindow in front of a QGraphgicsView view ? Many thanks!

Do you want the graphics view to be the background of the mdi area? If so, try setting the view as the viewport for the mdi area although personally I don't see a use case for such configuration. Are you sure about doing that? What is your goal?
