Usage 2:
listenerObject = new Object();
listenerObject.click = function(eventObject){
...
}
windowInstance.addEventListener("click", listenerObject)
Description
Event; broadcast to all registered listeners when the mouse is clicked (released) over the
close button.
The first usage example uses an
instance. The keyword
component instance. For example, the following code, attached to the Window instance
, sends "_level0.myWindow" to the Output panel:
myWindow
on(click){
trace(this);
}
The second usage example uses a dispatcher/listener event model. A component instance
( ) dispatches an event (in this case,
windowInstance
function, also called a handler, on a listener object (
a method with the same name as the event on the listener object; the method is called when the
event is triggered. When the event is triggered, it automatically passes an event object
( ) to the listener object method. The event object has properties that contain
eventObject
information about the event. You can use these properties to write code that handles the event.
Finally, you call the
instance that broadcasts the event to register the listener with the instance. When the instance
dispatches the event, the listener is called.

Example
The following example creates a modal window and then defines a click handler that deletes the
window. You must add a Window component to the Stage and then delete it to add the
component to the document library; then add the following code to Frame 1:
import mx.managers.PopUpManager
import mx.containers.Window
var myTW = PopUpManager.createPopUp(_root, Window, true, {closeButton: true,
title:"My Window"});
windowListener = new Object();
windowListener.click = function(evt){
_root.myTW.deletePopUp();
}
myTW.addEventListener("click", windowListener);
