body: <p>How to implement vertical line and arrows altogether in Ext Tree?</p>
  
  <p>I have created a fiddle by using both properties of <code>useArrows</code> and <code>lines</code>, but not getting applied at the same time.</p>
  
  <pre><code>     Ext.create('Ext.tree.Panel', {
          title: 'Simple Tree',
          width: 200,
          height: 200,
          store: store,
          rootVisible: true,
          lines:true,
          useArrows: true,
          renderTo: Ext.getBody()
      });
  </code></pre>
