Class RedoAction

java.lang.Object

All Implemented Interfaces:
java.awt.event.ActionListener, java.io.Serializable, java.lang.Cloneable, java.util.EventListener, javax.swing.Action

public class RedoAction
extends AbstractViewAction

Redoes the last user action on the active view.

This action requires that the View returns a project specific redo action when invoking getActionMap("redo") on a View.

This action is called when the user selects the Redo item in the Edit menu. The menu item is automatically created by the application.

If you want this behavior in your application, you have to create an action with this ID and put it in your ApplicationModel in method ApplicationModel.initApplication(org.jhotdraw.app.Application).
