Draw polygon with image inside

Lunarix

Hello,
I'd like to draw a polygon in a QGraphicsView. This works. Now I'd like to add a "background" image for the polygon.
A simple color like green works, but I'd like to use my own .png image.

    QVector<QPointF> hexPoints;
    hexPoints << QPointF(71,20) <<QPointF(35,0) <<QPointF(0,20) <<
                 QPointF(0,50) <<QPointF(35,71) <<QPointF(71,50);
    QPolygonF my_polygon(hexPoints);

    QImage *myImage = new QImage("my.png");
    if(myImage->isNull()){
        std::cout << "Could not read image!" << std::endl;
    }
    QBrush *myb = new QBrush(*myImage);

    QPen outlinePen(Qt::black);

    QGraphicsScene *scene = new QGraphicsScene(this);
    scene->addPolygon(my_polygon,outlinePen,*myb);
    ui->graphicsView->setScene(scene);

But sadly there is no image in my polygon.
How to fix it?
Thanks in advance!

@Lunarix
did you try setting the brush style to Qt::TexturePattern?

Hello @kenchan,
I added

    QBrush *myb = new QBrush(*myImage);
    myb->setStyle(Qt::TexturePattern); // added

but still, I can not see any image :/ what do I do wrong?

Solved it. The image was white where it was displayed - works with different image. x.x
