Standard behaviors like the get and set methods for <code>Action</code> object properties (icon, text, and enabled) are defined here. The developer need only subclass this abstract class and define the <code>actionPerformed</code> method. <p> <strong>Warning:</strong> 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.
