QPolygon: How do I obtain the edges of the polygon

Question

I am using QPolygon class. Is there any method which gives the edges of the respective polygon?

Answer 1

If by edges you mean the bounding box (smallest rectangle that encloses the polygon) then it's boundingRect().

If you are talking about the edges that are made up of vertexes, then they are just lines in the polygon. QPolygon is just a QVector<QPoint> derived class. The edges are the lines constructed with consecutive QPoints in the list (plus the one from the last point to the first).
