title: how to imitate a link click in QTextBrowser
body: <p>Actualy, i have different tabs.
  what I wanted to achieve is, 
  - user clicked a link from tab 1
  - and it will immediately display QTextBrowser in tab 2, at the html anchor i set.</p>
  
  <p>Is there a way of doing this?</p>
  
  <p>I've managed to switch tab by using tabWidget.setCurrentWidget()
  now the question is, how to set the focus to the desired html anchor place of the QTextBrowser.</p>
  
  <p>Thanks in advance.</p>
