Assuming you have access to the item's paint function:

void MyGraphicsItem::paint(painter, option, widget) {
   QGraphicsView* whichView = 0;
   for (int i = 0; i < scene()->views().size(); ++i)
        if (scene->views()[i]->viewport() == widget)
            whichView = scene->views()[i];
}

There's probably a nicer way to code this, but this is the direction.
