void com.arcle.rmt.j2se.swing.ui.ActionWrapper.actionPerformed (  ActionEvent  e  )

Template method which wraps the doActionPerformed event handler with an exception-handling construct. When the wrapped event handler throws an exception, the exception is shown in a dialog. Reimplemented in com.arcle.rmt.j2se.swing.ui.ExceptionSafeActionWrapper. Definition at line 101 of file ActionWrapper.java. References com.arcle.rmt.j2se.swing.ui.ActionWrapper.getWrappedObject().

void com.arcle.rmt.j2se.swing.ui.ActionWrapper.addPropertyChangeListener (  PropertyChangeListener  listener  )

Adds a PropertyChange listener. Containers and attached components use these methods to register interest in this Action object. When its enabled state or other property changes, the registered listeners are informed of the change. Parameters: listener  a PropertyChangeListener object Definition at line 164 of file ActionWrapper.java. References com.arcle.rmt.j2se.swing.ui.ActionWrapper.getWrappedObject().

Object com.arcle.rmt.j2se.swing.ui.ActionWrapper.getValue (  String  key  )

Gets one of this object's properties using the associated key. See also: putValue Definition at line 111 of file ActionWrapper.java. References com.arcle.rmt.j2se.swing.ui.ActionWrapper.getWrappedObject(). Referenced by com.arcle.rmt.j2se.swing.ui.ExceptionSafeActionWrapper.actionPerformed().

Action com.arcle.rmt.j2se.swing.ui.ActionWrapper.getWrappedObject (   )  [protected]
