title: Is it possible to set multiple items selected in QTreeWidget?
body: <p><code>setCurrentItem</code> only sets one item selected. I don't see any method to set more than 1 item selected programmatically, but maybe I'm overlooking something?</p>
  
  <p>Of course, my tree widget is configured to enable multiple selection.</p>
  
  <p>Note that I'm using <code>QTreeWidget</code>, not <code>QTreeView</code>.</p>
