title: Alternative way to get a reference to the underlying Ext.Window element of Ext.MessageBox in ExtJS4
body: <p>In ExtJS 3 I am using method <code>getDialog()</code> to get reference of underlying <code>Ext.Window</code> element of Ext.MessageBox</p>
  
  <p>In ExtJS 4 there is no such method which can get me this reference.</p>
  
  <p>Part of code, I am using now:</p>
  
  <pre><code>var msgBox = Ext.MessageBox.getDialog()
  </code></pre>
  
  <p>Is there any other way to get this reference?</p>
