title: How do I programmatically set the hidden property for a Tab (button)
body: <p>I have an Ext TabPanel, and I am trying to set the hidden property for one of the Tabs, programmatically. I am able to select the object and call methods such as disable() and enable() but so far have been unable to find a means by which I can manipulate the Tab's 'hidden' property.</p>
  
  <p>The Tab is defined as</p>
  
  <pre><code>{
      id: "view-task",     
      hidden: false,
      title: "View"
  }
  </code></pre>
  
  <p>and the code attempting to manipulate it</p>
  
  <pre><code>twin = (  Ext.getCmp('view-task'));
  twin.disable(); 
  </code></pre>
  
  <p>The above call to disable works, so the component is being correctly selected but I do not know how to manipulate the hidden property.</p>
  
  <p>Any assistance will be much appreciated.</p>
