Conical gradients interpolate interpolate colors counter-clockwise around a center point.
The colors in a gradient is defined using stop points of the
QGradientStop type, i.e. a position and a color. Use the
setColorAt() or the
setStops() function to define the stop points. It is the gradient’s complete set of stop points that describes how the gradient area should be filled. If no stop points have been specified, a gradient of black at 0 to white at 1 is used.
Note that the
setSpread() function has no effect for conical gradients. The reason is that the conical gradient is closed by definition, i.e. the conical gradient fills the entire circle from 0 - 360 degrees, while the boundary of a radial or a linear gradient can be specified through its radius or final stop points, respectively.
