How to set variable length of a TextArea?

i set width of textarea , have length automatically adjust amount of text put in it, avoiding insertion of scrollbar.

i've been unable find question answered in either documentation or forum archives.

 

i read somewhere if set width absolute number , omitted height, job, doesn't. gives me textarea 2 lines high scrollbar. (and, i'd prefer use widths percents, if possible).

 

here sample code using absolute heights:

 

<?xml version="1.0" encoding="utf-8"?>
<mx:application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" applicationcomplete="loadxml()" >

<mx:script>     <![cdata[
         [bindable]
         var xmldata:xml;
        var urlloader = new urlloader();

private function loadxml():void
    {    urlloader.addeventlistener(event.complete,onxmlloaded); urlloader.load(new  urlrequest("../data/paralog.xml"));    }

function onxmlloaded(e:event):void{  xmldata =  new xml(e.target.data); }
     ]]> </mx:script>
          
    <mx:panel title="{xmldata.title.tostring()}" height="400" width="600" layout="vertical"
        horizontalalign="center" status="status area" >

 

    <mx:textarea width="200"
        htmltext="{xmldata.detail.docket.tostring()
        + '&lt;br&gt;' + xmldata.detail.date.tostring()}"
        />

 

    <mx:vbox width="500" borderstyle="solid" paddingtop="10" paddingbottom="10" paddingleft="10" paddingright="10"   >
         <mx:textarea width="200" editable="false"  text="{'question:' + xmldata.issue.(@id=='i1').question.tostring()}"/>
        <mx:hbox width="550" >
             <mx:textarea width="200" editable="false"  text="{xmldata.*.claim.(@id=='i1y').statement.tostring()}"/>
             <mx:textarea width="200" editable="false"  text="{xmldata.*.claim.(@id=='i1n1').statement.tostring()}"/>
        </mx:hbox>
    </mx:vbox>
     </mx:panel>  

</mx:application>

 

fyi, here's xml i'm reading in:
