Is it possible to overlay graphics on top of QVideoWidget? (I'm using QVideoWidget with QCamera and would like to add graphics to Camera's view finder.)

I tried to inherit own class from QVideoWidget and override paintEvent() method:

void OwnVideoWidget:aintEvent(QPaintEvent * ev)
{
QVideoWidget:aintEvent( ev );
QPainter painter(this);
painter.setPen(Qt::blue);
painter.setFont(QFont("Arial", 30));
painter.drawText(rect(), Qt::AlignCenter, "Qt");
}
But this does not work (S60 5.x platform). Do you have any ideas how to achieve this kind of functionality?

Thanks, Veikko
