Set EllipseItem center to position

[maverick_pol]

This is a part of my code which I would like to work:

m_originationPoint = m_scene->addEllipse(0,0,6,6);
m_originationPoint->setFlag(QGraphicsItem::ItemIgnoresTransformations);
m_originationPoint->setZValue(1);
......
void   MyClass::vSetPos(QPointF _pos) {
    m_originationPoint->setPos(_pos);// This sets the topLeft boundingRect
 
}

m_originationPoint = m_scene->addEllipse(0,0,6,6);
m_originationPoint->setFlag(QGraphicsItem::ItemIgnoresTransformations);
m_originationPoint->setZValue(1);
......
void   MyClass::vSetPos(QPointF _pos) {
    m_originationPoint->setPos(_pos);// This sets the topLeft boundingRect

}

To copy to clipboard, switch view to plain text mode 

Thanks for any ideas.

Simply make the ellipse start from -3, -3 and extend 6 units wide and 6 unit high instead of 0,0 and 6,6. It should all work then - setPos() will set the position of the centre of the ellipse.

Hi,

Unfortunately, for me, your are totally right. This works.
Why unfortunately? Because I have found a different solution, which was far more complex and I coded it.
Ok...Sorry for the stupid problem.
