Re: [flexcoders] Color in textArea

[Tom Fitzpatrick]

Manish -

Thanks - but that doesn't work for my situation.

I'm trying to add the color during the process of building a string that 
will be pulled into a textArea.

Something like the following (doesn't work, but shows you what I'm trying 
to do):

<?xml version="1.0"?>
<mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml";
   xmlns="*" creationComplete="">
   <mx:Text id="t" text="start" />
   <mx:Button label="Color" click="createText()"/>
   <mx:Script>

         function doRed(text):String
     {
                 var tf = new TextFormat();
                 tf.color = 0xFF0000;
                 text.setTextFormat(tf);
                 return text;
     }

         function doBlack(text):String
     {
                 var tf = new TextFormat();
                 tf.color = 0x000000;
                 text.setTextFormat(tf);
                 return text;
     }

         function createText():Void
         {
                 var textA = "Terrific vs. ";
                 var textB = "Not so good";
                 textA = doRed(textA);
                 textB = doBlack(textB);
                 t.text = textA+textB;
         }
   </mx:Script>
</mx:Application>

>labelField is an undocumented property.  It's of type TextField.
