How to change background of QGraphicsTextItem?

I want to add a QGraphicsTextItem and I want to change the color of the background. By this I mean i want the boundingRect that contains the text to have a specific color. One way to do this would be to create a QGraphicsRectItem and put it on the back on the text, but I was wondering If there was another way to do this?

Thanks for any help!

This might be too little, too late, but the following worked for me, without having to sub-class or re-implement something.

item->setHtml(QString("<div style='background:rgba(255, 255, 255, 100%);'>" + QString("put your text here") + QString("</div>") );

You can write HTML into a QGraphicsTextItem using setHtml(), so you can fill the background with e.g.

 item->setHtml("<div style='background-color:#666666;'>" + yourText + "</div>");

I would subclass QGraphicsTextItem, for example:

class QGraphicsTextItemWithBackgroundColorOfMyChoosing : public QGraphicsTextItem
{
    public:
        QGraphicsTextItemWithBackgroundColorOfMyChoosing(const QString &text) :
            QGraphicsTextItem(text) { }

        void paint( QPainter *painter, const QStyleOptionGraphicsItem *o, QWidget *w) {
            painter->setBrush(Qt::red);
            painter->drawRect(boundingRect());
            QGraphicsTextItem::paint(painter, o, w); 
        }   
};
