Class LazyImageIcon

java.lang.Object

javax.swing.ImageIcon

resources.icons.LazyImageIcon

All Implemented Interfaces:

Serializable, Accessible, Icon, FileBasedIcon

Direct Known Subclasses:

BytesImageIcon, DerivedImageIcon, UrlImageIcon

public abstract class LazyImageIcon
extends ImageIcon
implements FileBasedIcon

LazyImageIcon provides the ability to instantiate an ImageIcon with delayed loading. In addition to delayed loading it has the added benefit of allowing the use of static initialization of ImageIcons without starting the Swing thread which can cause problems when running headless.
