All Implemented Interfaces:

java.awt.event.ActionListener, java.io.Serializable, java.lang.Cloneable, java.util.EventListener, javax.swing.Action

public class DuplicateAction
extends AbstractSelectionAction

Duplicates the selected region.

This action acts on the last EditableComponent / JTextComponent which had the focus when the ActionEvent was generated.

This action is called when the user selects the Duplicate 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).

Design Patterns
