title: Putting a close button on QTabWidget
body: <p>I'm using a <code>QTabWidget</code> to render multiple documents in a window, and I want to draw a close button on each tab. I'm using <em>Vista</em> and <em>Qt4</em>, so the tab widget is a native windows control; this may affect the feasibility.</p>
  
  <p>Does anyone know if it is possible to do this using the <code>QTabWidget</code> control, or do I have to create a custom widget? If creating a new widget is the only option, any pointers would be much appreciated; I'm relatively new to Qt.</p>
