Hi,

I am writing a simple scanline renderer, and would like to draw the image as it's generated, line by line.

I am using QGraphicsScene in order to display it. I am having two problems:

- QGraphicsScene only accepts QPixmaps, and I am unable to find a way of drawing pixels into them (apart from converting them into QImages).
- I cannot find a way of painting over a QPixmap that is part of a QGraphicsScene. There is a way of doing so?

Maybe there is other way of doing this, any comments are welcome.

Thanks in advance,
Jorge
