\title Gradients
\ingroup examples-painting
\brief Shows how gradients can be used with QPainter.
\brief In this example we show the various types of gradients that can
be used in Qt.
\image gradients-demo.png
There are three types of gradients:
\list
\li \b{Linear} gradients interpolate colors between start and end points.
\li \b{Radial} gradients interpolate colors between a focal point and the
points on a circle surrounding it.
\li \b{Conical} gradients interpolate colors around a center point.
\endlist
The panel on the right contains a color table editor that defines
the colors in the gradient. The three topmost controls determine the red,
green and blue components while the last defines the alpha of the
gradient. You can move points, and add new ones, by clicking with the left
mouse button, and remove points by clicking with the right button.
There are three default configurations available at the bottom of
the page that are provided as suggestions on how a color table could be
configured.
