/**
 
* Defines common behaviors for buttons and menu items.

* Buttons can be configured, and to some degree controlled, by

Using an

Refer to <a href="Action.html#buttonActions">
 
* Swing Components Supporting <code>Action</code></a> for more

* <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.
  
As of 1.4, support for long term storage
