Class VisADCanvasJ2D

  • All Implemented Interfaces:
    java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, java.lang.Runnable, javax.accessibility.Accessible

    public class VisADCanvasJ2D
extends javax.swing.JPanel
implements java.lang.Runnable
    VisADCanvasJ2D is the VisAD "Canvas" for Java2D. But not really a Canvas, since Canvas is heavyweight.
