| BasicGradientPainter | | public class BasicGradientPainter extends AbstractGradientPainter (Code) | | A Gradient based Painter that uses GradientPaint to paint the gradient.
Simply specify the GradientPaint to use.
In order for resizing to work properly with GradientPaint
it is necessary that the various control points used in
these paints be specified in such a manner that they can be reliably resized.
For example, BasicGradientPainter takes GradientPaints who's point1 and point2
properties are specified between 0 and 1, representing at what percentage of
the distance from the origin the gradient begins and ends. Thus, if I created
a GradientPaint like this:
GradientPaint gp = new GradientPaint(
new Point2D.Double(.2d, 0),
Color.BLUE,
new Point2D.Double(.8d, 0),
Color.WHITE);
then when painted, the gradient will start with a BLUE at 20% of the width of
the component, and finish with WHITE at 80% of the width of the component.
Various built in gradients also exist as public static final properties.
They are defined as GradientPaints rather than BasicGradientPainters because
BasicGradientPainter is mutable and thus don't make very reliable public static
final defaults. To use:
panel.setBackgroundPainter(new BasicGradientPainter(BasicGradientPainter.BLUE_EXPERIENCE));
