ooops... ui.addListener(this) ; is no necessary now in your test in my last
message;)

Hello :)
you can but a good event model use AsBroadcaster or other system to
dispatch the events :) In my personnal AS2 OpenSource framework i use a
event model compatible with W3C Dom3 event model for example (like AS3
framework).... it's more easy to use a event model to dispatch information
in callbacks methods ! If you want dispatch the information in your class...
use this.addListener(this) and you can use onX method directly on your
instance :)
class MyUIObject
{
/**
* Constructor of the class.
*/
public function MyUIObject()
{
this.addListener(this) ;
}
/**
* Inject addListener, removeListener and broadcastMessage methods in
the prototype of the class.
*/
static private var __INITBROADCASTER__ = AsBroadcaster.initialize(
MyUIObject.prototype ) ;
// Public Properties
/**
* The code of this method is injected by the AsBroadcaster tool.
* Use this declaration in the AS2 compilation.
*/
public var addListener:Function ;
/**
* The code of this method is injected by the AsBroadcaster tool.
* Use this declaration in the AS2 compilation.
*/
public var broadcastMessage:Function ;
/**
* This method is empty but can be override by the user in this code
to notify the x value modification.
*/
public var onX:Function ;
/**
* The code of this method is injected by the AsBroadcaster tool.
* Use this declaration in the AS2 compilation.
*/
public var removeListener:Function ;
/**
* (read-write) Returns the x position of the ui object.
*/
public function get x():Number
{
return getX() ;
}
/**
* (read-write) Sets the x position of the ui object.
*/
public function set x( value:Number ):Void
{
setX( value ) ;
}
// Public Methods
/**
* Returns the x position of the UI object.
*/
public function getX():Number
{
return _x;
}
/**
* Sets the x position of the UI object.
*/
public function setX( value:Number ):Void
{
_x = value ;
broadcastMessage("onX" , this, _x) ;
}
// Private Properties
/**
* The internal x position of the UI object.
*/
private var _x:Number ;
}
And in your code :
var ui:MyUIObject = new MyUIObject();
ui.onX = function ( who , x )
{
trace("onX : " + who + " with the value : " + x) ;
}
ui.addListener(this) ;
ui.x = 25 ;
EKA+ :)
