QLinearGradient Class Reference |
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 QGradient::setColorAt() or the QGradient::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.

Constructs a default linear gradient with interpolation area between (0, 0) and (1, 1).
See also QGradient::setColorAt(), setStart(), and setFinalStop().
Constructs a linear gradient with interpolation area between the given start point and finalStop.
See also QGradient::setColorAt() and QGradient::setStops().
Constructs a linear gradient with interpolation area between (x1, y1) and (x2, y2).
