title: How to get the selected Tab of my TabPanel in GWT
body: <p>I have created a <code>TabPanel</code> in GWT and add tabs 
  Now I want to get the selected tab so that if a user clicks on a close button, I can close that selected tab.</p>
  
  <p>Here is my tabpanel code:</p>
  
  <pre><code>    TabPanel tabPanelCvs =new TabPanel();
      tabPanelCvs.setVisible(true);
      tabPanelCvs.setSize("900","800");
      VerticalPanel vpnlCvsTab = new VerticalPanel();
      tabPanelCvs.add(vpnlCvsTab,result.getResumeTitle());
  </code></pre>
  
  <p>Any idea how can I get the selected tab of my <code>TabPanel</code>? </p>
