How to set a QPalette::Window to a QGraphicsScene?

Lays147

Hi guys,
I'm trying to set this color rule QPalette::Window to be a background in a QGraphicsScene,
but so far I dont be able to do it.
I tried some the code bellow:

QPalette p(palette());
    p.setBrush(Qt::Window);
    setPalette(p);
/* --*/
setPalette(QPalette(QPalette::Window));
/*---*/
QPalette p(palette());
    p.setColor(QPalette::Window,Qt::gray);
    scene()->setPalette(p);

How i do this?

i think setting it on the QGraphicsView would be more correct.
Alternatively you can subclass QGraphicsView and reimplement QGraphicsView::drawBackground()

If only you want changed background color for QGraphicsScene, then:

scene()->setBackgroundBrush(palette().window());
