jv.object.PsActionSupport

public final class PsActionSupport
extends java.lang.Object

This class may be used to add the functionality of sending ActionEvents to registered listeners to some class.
Put an instance of PsActionSupport into your class (as a member variable) and write methods addActionListener and removeActionListener that only call the methods from PsActionSupportwith the same name. Whenever you want an ActionEvent to be posted, just call fireAction(ActionEvent) of your PsActionSupport instance.
