  <a href="http://www.codingcolor.com/as3/as3-youtube-chromless-api/" rel="nofollow noreferrer">http://www.codingcolor.com/as3/as3-youtube-chromless-api/</a></p>
  
  <p>I have download the source code...but I couldn't figure out how he add the play, pause and stop button in the stage. I know in his VideoPlayerControl.as, he has</p>
  
  <pre><code>playbackControl = new PlayPauseButton();
  playbackControl.addEventListener(Event.CHANGE,setPlaybackState);
  addChild(playbackControl); 
  </code></pre>
  
  <p>in his PlayPauseButton.as. there is not code for the location of the button(x,y)..
  I am not sure how he place the control buttons....</p>
  
  <p>Also...Are there anyways to give the button location with object oriented way instead of specify it with static number???</p>
  
  <p>I appreciate any help...</p>
