title: ExtJs: Applying height and width through css style does not work
body: <p>I have the following code:</p>
  
  <pre><code>var win = new Ext.Window({
  width:200,
  height:200, 
  autoScroll: true,
  closable: false,
  border: false,
  shadow: true,
  draggable: false
  });
  
  win.show();
  </code></pre>
  
  <p>And I want to use css styles to set the width and height, look the follwoing code:
  Code:</p>
  
  <pre><code>var win = new Ext.Window({   
  cls: 'test-class',
  autoScroll: true,
  closable: false,
  border: false,
  shadow: true,
  draggable: false
  });
  
  win.show();
  </code></pre>
  
  <p>css style class:</p>
  
  <pre><code>.test-class {
   height:200px; 
   width:200px;
   background:blue;
   }​
  </code></pre>
  
  <p>But the height and width are not set, instead the background yes. </p>
  
  <p>Can you let me know how can I set the width and height through css style classes?
  I am using ExtJs. 4.0.</p>
  
  <p>Thank you in advance.</p>
