The `QConicalGradient` class is used in combination with `QBrush` to specify a conical gradient brush. More ## Detailed Description¶

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.

In addition to the functions inherited from `QGradient` , the `QConicalGradient` class provides the `angle()` and `center()` functions returning the start angle and center of the gradient.

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.
