Class BasicSliderUI.ActionScroller

java.lang.Object
javax.swing.AbstractAction
javax.swing.plaf.basic.BasicSliderUI.ActionScroller
All Implemented Interfaces:
ActionListener, Serializable, Cloneable, EventListener, Action
Enclosing class:
BasicSliderUI 
public class BasicSliderUI.ActionScroller extends AbstractAction
As of Java 2 platform v1.3 this undocumented class is no longer used. The recommended approach to creating bindings is to use a combination of an ActionMap, to contain the action, and an InputMap to contain the mapping from KeyStroke to action description. The InputMap is usually described in the LookAndFeel tables.

Please refer to the key bindings specification for further details.

This class should be treated as a "protected" inner class. Instantiate it only within subclasses of Foo.
