QRadialGradient 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 QRadialGradient class provides the center(), focalPoint() and radius() functions returning the gradient's center, focal point and radius respectively.

Constructs a radial gradient with the center and focal point at (0, 0) with a radius of 1.
Constructs a radial gradient with the given center, radius and focalPoint.
See also QGradient::setColorAt() and QGradient::setStops().
Constructs a radial gradient with the given center (cx, cy), radius and focal point (fx, fy).
See also QGradient::setColorAt() and QGradient::setStops().
Constructs a radial gradient with the given center, radius and the focal point in the circle center.
See also QGradient::setColorAt() and QGradient::setStops().
Constructs a radial gradient with the center at (cx, cy) and the specified radius. The focal point lies at the center of the circle.
