title: changing the background color of sencha touch panel
body: <p>I am trying to change background color of panel.</p>
  
  <p>Please see the code:</p>
  
  <pre><code>panel: {
              centered: true,
              width: 200,
              height: 150,
              style: 'background-color: red',
              fullscreen: false,
              hidden: true,
              zIndex: 10,
  
         }
  </code></pre>
  
  <p>but <strong><em>style: 'background-color: red'</em></strong> statement doesn't fulfill my requirements. it changes the color of panel border only not complete panel background color.</p>
  
  <p>please suggest for the same.</p>
  
  <p>thanks!</p>
