Detailed Description#

Linear gradients interpolate colors between start and end points. Outside these points the gradient is either padded, reflected or repeated depending on the currently set spread method:

PadSpread (default)

ReflectSpread

RepeatSpread

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 QLinearGradient class provides the finalStop() function which returns the final stop point of the gradient, and the start() function returning the start point of the gradient.

__init__()#

Constructs a default linear gradient with interpolation area between (0, 0) and (1, 1).

Parameters:

start – QPointF
finalStop – QPointF

Constructs a linear gradient with interpolation area between the given start point and finalStop.
