title: Show FrameView after HIDE_ON_CLOSE
body: <p>I have a problem with my Java app, I set the necessary for reduce to icon in traybar and set: </p>
  
  <pre><code>app.getMainFrame().setDefaultCloseOperation(HIDE_ON_CLOSE);
  </code></pre>
  
  <p>So when I close my app in taskbar will be close, but the app continue to run and it's visible the icon to taskbar.</p>
  
  <p>The problem is: How can I restore the app from the taskbar?</p>
  
  <p>I tried:</p>
  
  <pre><code>app.show(app.getMainView().getFrame());
  app.getMainView().getFrame().setVisible(true);
  app.getMainView().getFrame()setVisible(true);
  </code></pre>
  
  <p>but neither of them worked.</p>
