I think QT has some bezier object. Maybe:

QPainterPath::cubicTo()

I think so. As far as I know, there is not graphics view item for arrangement.
You'll need to draw each curve of the arrangement one by one.

I'm just not sure how could I draw it in correct way.
In case, that I would have in arrangement just line segments it would be easy, but if I have curved lines I can get source and target of the curve easily, but how to draw curved line between start and end points correctly? I still can't find any suitable Qt object for this drawing.

Thank you for your answers, I really appreciate that.
