Thanks,
Not sure if I will get a chance to look into it, might look to re-adapt/rewrite it at some point in future. Might just be the angles or sizing of some stuff is slightly off somewhere. Dont think i ever tested it for that kind of shape.
I do remember when creating it I was looking for a solution to 'cut out' the center, so that it would be transparent to what was underneath - probably due to clipping it wouldnt be, so would have to capture background of parent and paint that instead.
I remember thinking about the possibilities of having different shapes for other types of controls, semi-circular and the like (from -90 to 90 degree for example) for other gauges etc. But that was a long time ago.
Also the calculation for figuring out the placement of text around the circle was a bit of a pain from what i remember - probably could be optimized better.
Thanks for letting me know about that issue.
