The following example is an excerpt from the second full example provided in the entry for
the AsBroadcaster.initialize() method. It shows how to send arguments to listener
methods.
someObject.broadcastMessage("someEvent", 3, "arbitrary string");

public static initialize(obj:Object) : Void
Adds event notification and listener management functionality to a given object. This is a
static method; it must be called by using the AsBroadcaster class (where someObject is the
name of the object to be initialized as an event broadcaster):
AsBroadcaster.initialize(someObject);
Note: A common mistake is to capitalize the second letter of AsBroadcaster. When calling the
AsBroadcaster.initialize() method, ensure that the second letter is lowercase. Any
misspelling of AsBroadcaster will fail silently.
This method adds the _listeners property along with the following three methods to the
object specified by the obj parameter:
■ obj.addListener()
■ obj.removeListener()
■ obj.broadcastMessage()
Availability: ActionScript 1.0; Flash Player 6
Parameters
obj:Object - An object to serve as a broadcasting object.
Example
The following example creates a generic object, someObject, and turns it into an event
broadcaster. The output should be the strings shown in the two trace() statements:
var someObject:Object = new Object(); // Creates broadcast object.
var myListener1:Object = new Object(); // Creates listener object.
var myListener2:Object = new Object(); // Creates listener object.
