title: Property selectors in QT CSS
body: <p>I have a tree widget that I'm using for a user/room concept. How can I style the rooms independently from the users in the rooms? I'm assuming it has something to do with QT's property selector in CSS? I would like to be able to do this:</p>
  
  <pre><code>QTreeView::item[isUser="true"] { background: blue; }
  QTreeView::item[isRoom="true"] { background: red; }
  </code></pre>
