java.lang.Object

javax.swing.plaf.IconUIResource

All Implemented Interfaces:

Serializable, Icon, UIResource

public class IconUIResource
extends Object
implements Icon, UIResource, Serializable

An Icon wrapper class which implements UIResource. UI classes which set icon properties should use this class to wrap any icons specified as defaults. This class delegates all method invocations to the Icon "delegate" object specified at construction.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans has been added to the java.beans package. Please see XMLEncoder.
