Draw only a portion of Qt Curved Path

[Gurjot]

You could try QPainterPath::toSubpathPolygons(), which might get you back the polyline.

Thank you, your suggestion helped.

I got the list of QPolygonF from which I got a single QPolygonF. And then I created a new QPolygonF in which I only inserted those QPointF which were needed. And then I drew that.
