Re: QLinearGradient Coloring
It is going to use whatever the internal implementation is (maybe that's the chromatic circle, I don't know) to interpolate between stops. If you want some other interpolation scheme, you need to either write your own QGradient class. And since it looks like QGradient has no public methods for retrieving the color for a specific location, QBrush must have privileged access to QGradient (friend status) so you'll have to look into the QBrush and QGradient source code to find out in detail how to implement your own gradient class.
