Class ResourceImageIcon

java.lang.Object
  javax.swing.ImageIcon
      dsto.dfc.swing.icons.ResourceImageIcon

All Implemented Interfaces:

ImageObserver, Serializable, Accessible, Icon

public class ResourceImageIcon
extends ImageIcon
implements Icon, Serializable, ImageObserver

An icon that is loaded from a resource. The icon image is lazy loaded to speed up application initialization. Unfortunately the Swing designers have implemented auto-greying of icons only for ImageIcon's (by hardcoding calls to ImageIcon.getImage(): see AbstractButton for an example), so this class has to extend ImageIcon and override all its methods for icon disabling to work. If Sun ever fix this, the 'extends ImageIcon' may be removed.
