how to check QGrapicsView/QGraphicsScene size

[estel]

hello
I want to write something independent from device screen size. I want set position of icons on QGraphicsScene. I have to know the scene size in order to all icons set on the device screen (without scrollbar). Unfortunately I have no idea how to do it. Could you help me?

If anyone have the same problem, here is solution:

QGraphicsScene scene;
 
    QGraphicsView view(&scene);
    view.show();
 
    QRectF geometry = view.contentsRect();

QGraphicsScene scene;

    QGraphicsView view(&scene);
    view.show();

    QRectF geometry = view.contentsRect();

To copy to clipboard, switch view to plain text mode
