Folks,

I am trying to draw a multi segment line with different color of each part, is there any ways to do this with QPainterPath ?

Coz there will be hundreds of segments, so that would be great if not using hundreds of path.

QPainterPath only stores shapes, not their properties such as colours.

QGradient and its subclasses might be of interest to you

thanks, i know QPainterPath doesnt maintain any information regarding color.
however, I want drawing a multi-color line into QGraphicsScene for better rotate/zoom in-out handling.

is there any similar approaches ?

QPainterPath itself has nothing to do with "drawing". If you want to draw something, take a look at QPainter class. There is a QPainter::drawLine() method that is meant to draw lines. You can loop over your set of lines, change pen colours and draw lines.
