title: Qt Style Sheet - Different styles for same type widgets
body: <p>I need to assign different styles for the same typed widget instances. Specially for QActions. Following style sheet sets QActions' background images, actualy tool buttons'.</p>
  
  <pre><code>QToolButton
  {
      background-image: url(bg.png);
  }
  </code></pre>
  
  <p>But I need to assign different backgrounds for tool buttons like this.</p>
  
  <pre><code>QToolButton::actClose
  {
      background-image: url(close.png);
  }
  QToolButton::actOpen
  {
      background-image: url(open.png);
  }
  </code></pre>
  
  <p>Is there any easy way like this or is it not possible?</p>
