[flexcoders] How to make TextArea resize to fit content

[Guillermo Villasana]

Hello, I have been searching around to find out how to make htmlText (or 
Text if is used instead of htmlText) in TextArea to resize in height so 
that it won't make a scroll.
This is what I was able to understand to achive the problem and 
generated this class:


<code>
package myclases
{
    import mx.controls.TextArea;
    import flash.text.TextLineMetrics;
    public class AdvancedTextArea extends TextArea
    {
        public function AdvancedTextArea() {
            super();
        }
       
        // The default size is the size of the text plus a 10 pixel margin.
        override protected function measure():void {
            super.measure();
       
            // Calculate the default size of the control based on the
            // contents of the TextArea.text property.
            var lineMetrics:TextLineMetrics = measureText(text);
            // Add a 10 pixel border area around the text.
            measuredHeight = measuredMinHeight = lineMetrics.height + 10;
        }
    }
}
</code>

then I use it in an action script like this:

<code>
    pTextArea=new AdvancedTextArea();
    pTextArea.invalidateSize();
    pTextArea.width=300;
     pTextArea.text="a very very long text that should wrap around in a 
300px width Text Area. This text is dynamic....;"
    myCanvas.addChild(pTextArea);
</code>

Still the TextArea will not resize it's height and the scrollbar 
appears, what am I doing wrong? How can I resize the pTextArea after the 
Text or htmlText property is set?

Thanks for any help
