Re: [flexcoders] Event Handlers inside custom components

I actually figured this out right after I asked but I did it a different way.

It does basically the same thing though.

 

Here is an example:

 

<!—My application page (TestApp.mxml)-- >

---------------------------------------------------------------------------------------------------------------------------------------------------------------------

<?xml version="1.0" encoding="utf-8"?>

<mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml" xmlns:Weee="*" initialize="SetVar()">

<mx:Script>

<![CDATA[

function SetVar(){

MyTest.MyValue = "Rararararar";

}

]]>

</mx:Script>

<Weee:MyTestComp id="MyTest" />

</mx:Application>

---------------------------------------------------------------------------------------------------------------------------------------------------------------------

<!—My component file (MyTestComp.mxml)-->

---------------------------------------------------------------------------------------------------------------------------------------------------------------------

<?xml version="1.0" encoding="utf-8"?>

<mx:VBox xmlns:mx="http://www.macromedia.com/2003/mxml" width="400" height="400">

<mx:Script>

<![CDATA[

var MyValue:String = "BlahBlah"

function set MyOtherValue(NewValue):Void {

mx.core.Application.alert('The new value is: '+MyValue);

}

]]>

</mx:Script>

<mx:Binding source="MyValue" destination="MyOtherValue" />

</mx:VBox>

---------------------------------------------------------------------------------------------------------------------------------------------------------------------
