add QImage to QGraphisScene

[myrabbitrules]

Hi!

I have my own subclass of QGraphicsView which displays a QGraphicsScene. I add lines on the scene. Now I also want do add QImages to the scene (or view).
I have tried the following:
I overode QWidget:: paintEvent(QPaintEvent*) in my QGraphicsView subclass:

void myViewSubclass:paintEvent(QPaintEvent * event) {
    QGraphicsView::paintEvent(event);
    QPainter painter;    
    painter.begin(this);
    QPointF point(GetCenter().x(), GetCenter().y());
    painter.drawImage(point, *image);
    painter.end();
}

void myViewSubclass:paintEvent(QPaintEvent * event) {
    QGraphicsView::paintEvent(event);
    QPainter painter;    
    painter.begin(this);
    QPointF point(GetCenter().x(), GetCenter().y());
    painter.drawImage(point, *image);
    painter.end();
}

To copy to clipboard, switch view to plain text mode 

Unfortunately Qt Creator tells me:

QPainter::begin: Widget painting can only begin as a result of a paintEvent

But I only paint in the above method which IS the result of a paint Event...
Where is my mistake? Or is my aprroach to drawing an image on the scene rubbish anyway?
