[Qt-interest] Rotation of QAbstractGraphicsShapeItem

[Jesús Fernández]

Hi,

I have a QGraphisScene with QGraphicsEllipseItem and I want to rotate and
resize it. The problem is when I try to rotate it when it has been
previously resized+rotated it appears to change the center of the rect.

Here is my code:
void GraphicsEllipseLandmarkItem::setAngle(qreal angle)

{

  QPointF center=boundingRect().center();


    if(m_angle==angle) return;

    m_angle=angle;

   resetTransform();

   translate(center.x(), center.y());

  rotate(m_angle);

  translate(-center.x(), -center.y());

   emit angleChanged(angle);

}


Regards
