title: Sencha Touch 2 instantiating a component with a background image
body: <p>I'm working with <code>Sencha Touch 2</code> components now.</p>
  
  <p>I'm facing the following issue:</p>
  
  <p>I set a background image to my components using stylesheets. My whole scene is made up of several components / containers having background images. When I instantiate my scene - the image loading process is asynchronous - i.e. my scene is displayed and then later images in the scene are loaded and displayed.</p>
  
  <p>I would like to know how to wait until all my images are loaded and then display my scene. In fact, I can use <code>Ext.Img</code> class and its <code>load</code> event, but this is what I don't want to do. I need to style my images (as backgrounds) using stylesheets.</p>
  
  <p>Thanks a lot.</p>
