Class DeleteAction

java.lang.Object
  javax.swing.AbstractAction
      javax.swing.text.TextAction
          org.jhotdraw.app.action.edit.DeleteAction

All Implemented Interfaces:

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

Direct Known Subclasses:

RemoveAction

public class DeleteAction
extends javax.swing.text.TextAction

Deletes the region at (or after) the caret position.

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 Delete 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

Framework
The interfaces and classes listed below work together:
Contract: EditableComponent, JTextComponent.
Client: AbstractSelectionAction, DeleteAction, DuplicateAction, SelectAllAction, ClearSelectionAction.
