how to create a 2D speedometer. As in the picture.
I can't figure out what QPainter elements to draw them with ?????
I think QPainter.drawPie is not very suitable for this. I am thinking of drawing my own arch (but it requires a lot of code) is there a more affordable option ??

Simply two QPainter::drawArc() calls with a different color.
