[Solved] QGraphicsItem->mapToScene missplacing QPointF
-
!http://s22.postimg.org/lyqgxvvrl/arrow.png(Arrow)!
As you can see at the image, I'am trying to port the arrowhead point coordinates to GraphicsScene coordinates. I make a line with the same distance to the center, the point already ported in Scene coordinates:
@
//Item context (Custom QGraphicsItem).
QPointF drawer = this->getCableArrowPoint();
drawer = this->mapToScene(drawer);
QLineF line2(QPointF(drawer.x() - 50, drawer.y()), QPointF(drawer.x() +50, drawer.y()));
scene()->addLine(line2);
@As result, you can see the line is missplaced, a bit to the right where expected.
In fact, my problem is a bit complicated than that, but I'm trying to simplifie to this one I'm posting, because I think both problems have the same origin.
Why item->mapToScene is porting the item's point to an unexpected place (further to the right) in scene?
Something similar is happening while mapping to scene a QPainterPath.
Thank you.

what does the method getCableArrowPoint() exactly do?
Is the cableArrow item a child-item of "this" item?
