\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.
