+ \example demos/gradients
+ \title Gradients
+
+ In this demo we show the various types of gradients that can
+ be used in Qt.
+
+ \image gradients-demo.png
+
+ There are three types of gradients:
+
+ \list
+ \o \bold{Linear} gradients interpolate colors between start and end points.
+ \o \bold{Radial} gradients interpolate colors between a focal point and the
+ points on a circle surrounding it.
+ \o \bold{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.
