Writing QGraphicsItemGroup to a .png file?

[jesbb]

Is it possible to write a QGraphicsItemGroup (or the contents of a QGraphicsItemGroup) to an image file, specifically a .png? If it is, I'm not sure how to go about doing it.

Maybe something like that :)

@
QImage img(item->boundingRect().size().toSize(), QImage::Format_RGB32);
img.fill(QColor(255, 255, 255).rgb());
QPainter painter(&img;);
QStyleOptionGraphicsItem styleOption;
item->paint(&painter;, &styleOption;);
img.save(path);
@

where "item" is your QGraphicsItemGroup.

P.S. I'm not sure, but you can try..

I tried doing that, but it doesn't work; it only returns a blank image that's the same dimension of the QGraphicsItemGroup.
