[flexcoders] Disable the enter key mx:TextArea

[Andriy Panas]

   Because KeyboardEvents are not cancelable in Flash Player, you can
listen instead for "textInput" event and prevent starting the new line
if Enter key was pressed.

/////////////////////
<mx:Script>
     <![CDATA[

       private function txtInputHandler(event:TextEvent):void{
              if (event.text=="\n"){
                    event.preventDefault();
                    event.stopImmediatePropagation();
              }
       }

    ]]>
    </mx:Script>
    <mx:TextArea x="31" y="84" id="userInput"
textInput="txtInputHandler(event)"/>

/////////////////////

   But then mx:TextArea behaves like single-line mx:TextInput input control...
