Use that extended class exactly the same way you would use the base classs.

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 --- In [email protected] <mailto:flexcoders%40yahoogroups.com> , "Alex Harui" <[EMAIL PROTECTED]> wrote: > > See this thread: > > > > ________________________________ > > From: [email protected] <mailto:flexcoders%40yahoogroups.com> [mailto:[email protected] <mailto:flexcoders%40yahoogroups.com> ] On > Behalf Of Mark > Sent: Tuesday, September 11, 2007 10:34 AM > To: [email protected] <mailto:flexcoders%40yahoogroups.com> > Subject: [flexcoders] dynamic textArea sizing > > > > Is there a way for the textArea to size its Height to fit the text, as > apposed to setting a height in pixels?
