title: EXTJS 4 Render a panel like a messagebox
body: <p>What I am trying to accomplish is to add information to a datagrid, then what I have its a button 'add', when I click it, it will show a panel where I can add all the information needed to fill the datagrid. </p>
  
  <p>The panel to add the info should be shown like this:</p>
  
  <p><a href="http://img94.imageshack.us/img94/2662/emailhelp.jpg" rel="nofollow">http://img94.imageshack.us/img94/2662/emailhelp.jpg</a></p>
  
  <p>The one above I have done it with a messagebox like this:</p>
  
  <pre><code>     Ext.MessageBox.show({
          title : 'Email Information',
          msg : 'your email:',
          width : 300,
          buttons : Ext.MessageBox.OKCANCEL,
          multiline : true,
          fn : addEmailInfo,
          animateTarget : 'btn_add'
      });
  </code></pre>
  
  <p>Then what I want is something similar but with a panel, in which I could add more components.</p>
  
  <p>I've been searching but I havent found anything, thank you in advance.</p>
