title: Flex text change event
body: <p>I'm tracking how fast does the text of a textArea change. If it changes faster than 500 ms then i don't want to do anything, but if it doesn't change in 500 ms, i want to call a method.
  I tried like this:</p>
  
  <pre><code>public function textchangeListener(e : Event):void
          {
              if(((new Date).getTime() - changeTime)&gt;500)
              {
                  prepareText();
              }
  
              changeTime = (new Date).getTime();
          }
  </code></pre>
  
  <p>This method is the event handler for text change.
  But the problem is, if it changes only under 500 ms and after that it doesn't change, then my method won't be called. I make this for a better performance, so the prepareText() is called only when the user stops typing for 500 ms.</p>
