Dynamic creation of buttons and events. Event was not working.

Hi guys,.

I am trying to create an application that will dynamically create buttons and events... Creating a button isn't a problem, but the event did not work. The code below is simple... 1. click on the button and it will create another button (dynamic)... If you click on the newly created button it should alert a test2...

Anyone know how to implement this (which works )

<? XML version = "1.0" encoding = "utf-8"? >
" < = xmlns:mx mx:Application ' http://www.Adobe.com/2006/MXML "layout ="absolute"> "
< mx:Script >
<! [CDATA]

Mx.controls import. *;

private void onLoad (): void
{
var btn:Button = null;
//
Test2();
BTN = new Button();
BTN.label = "test";
btn.addEventListener ("click", test2);
this.addChild (btn);
}

private void test2 (): void
{
Alert.Show ('test', 'test');
}

[]] >
< / mx:Script >
< mx:HBox id = "testbox.foobar.com" x = "0" y = "154" width = "100%" >
< mx:Button label = "click" = "onLoad()"; / >
< / mx:HBox >

< / mx:Application >

Hi gretags,

You forgot to specify the argument in the eventListener... that's why you are getting the runtime script error...

Check the code below... Now the alert will appear...


http://www.Adobe.com/2006/mxml"layout ="absolute">
   
               
Mx.controls import. *;
       
       
private void onLoad (): void
{
var btn:Button = null;
//
Test2();
BTN = new Button();
BTN.label = "test";
btn.addEventListener ("click", test2);
this.addChild (btn);
}
       
private void test2(event:MouseEvent):void
{
Alert.Show ('test', 'test');
}
