QGraphicsRectItem with text

I subclass QGraphicsRectItem in order to add a text inside the rectangle.
1) The text doesn't get re-paint properly. When I created it as

Code:

RectItem *myRect = new JFIRectItem("A Very Long Long Word");
addItem(myRect);

it shows up on the QGraphicsScene fine, but the text is missing when I have it in a dropEvent

Code:

RectItem *item = new RectItem(m_selectedJFIName.c_str());
item->setPos(mouseEvent->scenePos());
addItem(item);

2) How am I going to wrap the text so that it will fit inside the rectangle and to also re-size the rectangle as needed

Code:

class RectItem : public QObject, public QGraphicsRectItem
{
  Q_OBJECT
  public:
    RectItem (std::string text=0, QGraphicsItem *parent = 0);
    void paint(QPainter *painter, const QStyleOptionGraphicsItem *option, 
      QWidget *widget = 0);
 
private:
  std::string m_text;
};
 
RectItem::RectItem (std::string text, QGraphicsItem *parent)
: QGraphicsRectItem(100, 100, 100, 30, parent)
{
  m_text = text;
}
 
void RectItem::paint(QPainter *painter, const QStyleOptionGraphicsItem *option, 
                        QWidget *widget)
{
  QPointF pos = QPointF(rect().x() + 10, rect().y() + 20);
  painter->drawText(pos, m_text.c_str());
  painter->setPen(QPen(Qt::black, 1));
  painter->drawRoundRect(rect());
}

Thanks.
