QGraphicsWidget shape only works down right from center

Hello,
I have made custom graphics widget with:

Code:

---

QRectF graphicsTask::boundingRect()
{
    return QRectF(-50, -50, 100, 100);
}
 
QPainterPath graphicsTask::shape()
{
    QPainterPath path;
    path.addEllipse(boundingRect());
    return path;
}

---

but it gets mouse events only on part of shape down and right of center of the item (bottom right quarter of a circle).
How can I make it work on all shape?

Move your ellipse up and to the left by 50 each:

Code:

---

path.addEllipse( QRectF( 0, 0, 100, 100 ) );

Hmmm.... why so?

This works perfectly fine:

Code:

---

#include <QtGui>
 
class Item : public QGraphicsItem {
public:
  Item(QGraphicsItem *parent = 0) : QGraphicsItem(parent) {}
  QRectF boundingRect() const { return QRectF(-50, -50, 100, 100); }
  QPainterPath shape() const { QPainterPath p; p.addEllipse(boundingRect()); return p; }
  void paint(QPainter *p, const QStyleOptionGraphicsItem *option, QWidget *widget = 0) {
    p->drawEllipse(boundingRect());
  }
protected:
  void mousePressEvent(QGraphicsSceneMouseEvent *e) {
    qDebug() << Q_FUNC_INFO;
  }
};
 
int main(int argc, char **argv) {
  QApplication app(argc, argv);
  QGraphicsScene sc;
  QGraphicsView view;
  view.setScene(&sc);
  sc.addItem(new Item);
  view.show();
  return app.exec();
}
