Hello,

I'm having issues getting a containers height after adding content to that
container. The code below shows you what I'm trying to do. I have tried to
validate the container and still get a 0 in height. Is there a reason why this
is happening because from my point of view, after I add an object to the
container the height of the container should change. Please help.

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"
creationComplete="init()" applicationComplete="check()">

<mx:Script>
<![CDATA[
import mx.containers.VBox;
import flash.utils.setInterval;
import mx.controls.Text;

private var txt:Text = new Text();
private var vBox:VBox = new VBox();

private function init():void {
txt.text = "Hello World";
vBox.addChild(txt);
this.addChild(vBox);
}

private function check():void {
setInterval(trace, 100, vBox.height);
}

]]>
</mx:Script>

</mx:Application>

Probably has to do with the fact you are calling check() in
applicationComplete, as this code works:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
creationComplete="init()">
<mx:Script>
<![CDATA[
import mx.containers.VBox;
import flash.utils.setInterval;
import mx.controls.Text;

private var txt:Text = new Text();
private var vBox:VBox = new VBox();

private function init():void {
txt.text = "Hello World";
vBox.addChild(txt);
this.addChild(vBox);
}

private function check():void {
setInterval(trace, 100, vBox.height);
}

<mx:Button label="Check Size" click="check()"/>
