This too, is valid: mx.events.EventDispatcher.initialize(this);
However, that adds 3 methods to each class instance, thus every time you create a new class instance or component, you now add more functions to memory for each instance, and you run that initialize function every time your class is created. If you put it up top as a static mixin: - she only runs once - you only add 3 methods to the protoytpe; all instances inherit them ----- Original Message ----- From: "Spencer Markowski" <[EMAIL PROTECTED]> To: "Flashcoders mailing list" <[email protected]> Sent: Friday, December 30, 2005 9:32 PM Subject: Re: [Flashcoders] Compoent Events Example (dispatch, listen, etc) It's fairly straightforward.. at least it is if what I'm about to show you is what you want to know. In your class file follow this basic structure. You'll need to import mx.events.EventDispatcher and add the three functions at the bottom to any class you wish to broadcast from. import mx.events.EventDispatcher; class SampleClass { function SampleClass() { //Register mx.events.EventDispatcher.initialize(this); } public function someFunction():Void { //Build an event object. Type is the name of the callback function you'll use. (listener.onDragRelease) var eventObject:Object = {target:this, type:'onDragRelease'}; //You can also add variables to pass into the event eventObject.position = getDropPosition(); //Send it away! dispatchEvent(eventObject); } /** * dispatchEvent * * Used to dispatch events * */ function dispatchEvent() { } function addEventListener() { } function removeEventListener() { } } To listen to those events you just need to add a listener that is listening for the event name you defined in the event object as type: applicationListener = new Object; applicationListener.onDragRelease= function(eventObj) { //trace(":: onDragRelease Event Recieved!"); //trace(eventObj.position); //Do something here with the data } var someObject:Object = {}; someObject.addEventListener("onDragRelease",applicationListener); Hope that helps you.
