Class ActionActionListener

java.lang.Object
  sale.ActionActionListener

All Implemented Interfaces:

Action, ActionListener, EventListener, Serializable

public class ActionActionListener

extends Object

implements Action, ActionListener

A special ActionListener that allows to associate Actions with buttons that are not in a FormSheet's button bar or a MenuSheet.

You can use subclasses of this class as ActionListeners on any button in a FormSheet that is not in the button bar. You can then think of it as of an Action associated with that button. The doAction(sale.SaleProcess, sale.SalesPoint) method will be called with the same parameters as for an Action associated with a button in the FormSheet's button bar.

If you do not override doAction(sale.SaleProcess, sale.SalesPoint) in subclasses, it will defer event handling to the Action object handed in on creation. Thus, you can create chains of responsibility which allow for, e.g., a capability to be associated with any ActionEvent in the FormSheet.
