Description
Event; broadcast to all registered listeners when a user opens a node on a Tree component.
Version 2 components use a dispatcher/listener event model. The Tree component dispatches
a event when a node is clicked open by a user; the event is handled by a function,
nodeOpen
also called a handler, that is attached to a listener object ( ) that you create.
listenerObject
You call the method and pass it the name of the handler as a parameter.
addEventListener()
When the event is triggered, it automatically passes an event object ( ) to the
eventObject
handler. Each event object has properties that contain information about the event. You can
use these properties to write code that handles the event. The event's event
Tree.nodeOpen
object has one additional property: (the XML node that was opened).
node
For more information, see "EventDispatcher class" on page 499.

occur, the listener functions call trace statements to display the event and the affected node in
