title: Individual QTreeWidgetItem indentation
body: <p>Is it possible to have individual indentation of items in a QTreeWidget?</p>
  
  <p>In specific, I have have a column containing both text, icon and for some of them a CheckBox. The items without a CheckBox gets shifted to the left so the indentation of the icon and the text is not inline with the others. Could maybe be fixed with a hidden CheckBox if that is possible?</p>
