Package org.jdesktop.swingx.color

Class GradientPreviewPanel

  • All Implemented Interfaces:
    java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, javax.accessibility.Accessible, javax.swing.Scrollable, AlphaPaintable, BackgroundPaintable
    public class GradientPreviewPanel
extends JXPanel

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