title: To build a flex volume control component similar to that of Youtube
body: <p>Hey, I've been assigned to design a flex 3 volume control component similar to the one Youtube players have. I mean, you move the mouse over the volume icon and a vertical slider appears.</p>
  
  <p>My only doubt is about how making this vertical slider to appear and to hide properly.</p>
  
  <p>Should I extend a PopUpButton somehow? Maybe another kind of PopUp component? Or do I really need to program the whole thing in actionscript(that would be just sad and sounds like reinventing the wheel)?</p>
  
  <p>Is anyone able to simply point me in the right direction? </p>
  
  <p>OBS: No need to teach me about skinning, designing.. or any of the rest. :)</p>
