Thanks, yeah I saw that but I'm not sure how to now add this Class
to the textArea component.
So here's my Class (just like he had) -
package com
{
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;
}
}
}
Now how do I get this on the MXML?
<mx:TextArea id="businesscase" width="100%" editable="false"
selectable="false" borderStyle="none"/>
Thanks
