SweepGradient

Creates a sweep gradient centered at center that starts at start_angle and ends at end_angle.

More information here.

Inherits: Gradient

Properties

  • center - The center of the gradient, as an offset into the (-1.0, -1.0) x (1.0, 1.0) square describing the gradient which will be mapped onto the paint box.
  • end_angle - The angle in radians at which stop 1.0 of the gradient is placed.
  • start_angle - The angle in radians at which stop 0.0 of the gradient is placed.

Properties​

centerclass-attributeinstance-attribute​

center: Alignment = field(default_factory=(lambda: Alignment.CENTER))

The center of the gradient, as an offset into the (-1.0, -1.0) x (1.0, 1.0) square describing the gradient which will be mapped onto the paint box.

For example, an flet.Alignment.CENTER will place the sweep gradient in the center of the box.

end_angleclass-attributeinstance-attribute​

end_angle: Number = math.pi * 2

The angle in radians at which stop 1.0 of the gradient is placed.

start_angleclass-attributeinstance-attribute​

start_angle: Number = 0.0

The angle in radians at which stop 0.0 of the gradient is placed.
