Class GradientPreviewPanel

java.lang.Object

java.awt.Component

java.awt.Container

javax.swing.JComponent

javax.swing.JPanel

org.jdesktop.swingx.JXPanel

org.jdesktop.swingx.color.GradientPreviewPanel

All Implemented Interfaces:

ImageObserver, MenuContainer, Serializable, Accessible, Scrollable, AlphaPaintable, BackgroundPaintable

public class GradientPreviewPanel
extends JXPanel

Dependency: Because this class relies on LinearGradientPaint and RadialGradientPaint, it requires the optional MultipleGradientPaint.jar
