Hi
I think you just broke GraphicsView normal handling.
Try also calling base class mousePressEvent as it might use for the actual item selection

void GraphicsView::mousePressEvent(QMouseEvent *event) { if(event->buttons().testFlag(Qt::LeftButton)) { int x,y; x = event->pos().x(); y = event->pos().y(); qDebug() << x << ", " << y; QPointF point = mapToScene(x, y); QGraphicsEllipseItem *ellipse; ellipse = scene->addEllipse(point.x(),point.y(),5,5,QPen(Qt::red), QBrush(Qt::red)); ellipse->setFlag(QGraphicsEllipseItem::ItemIsMovable); } // call base class QGraphicsView::mousePressEvent(event); }

Its not moving the pointer that is making it work. It is the QRect that I created to test. If I comment out
the rect it all goes back to not moving and only being created at 0,0
