[SOLVED] How to paint a QGraphicsItemGroup object?

[xtingray]

Hi,
Currently I am programming a basic dialog to visualize a QGraphicsItem object. Using the paint() method is working pretty well with the single items:

QGraphicsItem *item;
...
item->paint(painter, option, widget);

My problem occurs when I try to visualize a QGraphicsItemGroup object, I don't get any error message but only an empty area, if I try this code:

QGraphicsItemGroup *group;
...
group->paint(painter, option, widget);

So, I would like to know what is the right way to paint a group in this context? Thanks.

Finally, I found a nice way to visualize a QGraphicsItemGroup in an accurate way. Here is the code:

   if (QGraphicsItemGroup *group = qgraphicsitem_cast<QGraphicsItemGroup *>(item)) {
        foreach (QGraphicsItem *child, group->childItems())
                 child->paint(painter, option, widget);
    } else {
        item->paint(painter, option, widget);
    }

I hope this trick can be useful for somebody else ;)
