title: How to change the title bar height of spark.components.Panel?
body: <p>I'm creating a log-in box for my Flex application. However, I'm required to apply a specific design to this box that I have to change the title bar height.</p>
  
  <p>The component I'm using is spark.components.Panel. I just can't find the property of this 'Panel' component to change the feature.</p>
