title: Ext JS Display Field in Combo Box's Tooltip
body: <p>I'm trying to create an override to display a tooltip when the user hovers over a combo list item. My override looks like this:</p>
  
  <pre><code>Ext.override(Ext.form.ComboBox, {
       tpl: '&lt;tpl for="."&gt;',
               '&lt;div ext:qtip="{Name}" class="x-combo-list-item"&gt;{Name}&lt;/div&gt;',
             '&lt;/tpl&gt;'
  });
  </code></pre>
  
  <p>Is there a way I can access the combo box's <code>displayField</code> in the <code>tpl</code> instead of <code>{Name}</code>?</p>
