Qt is perfectly capable of adding a checkbox in an item view like you 
are trying to do, so something else is wrong. I don't use QTreeWidget 
much myself, so at first glance I don't the problem, but I would 
recommend you try to get it to work with the normal view classes, and 
not use widgets in your items if you can avoid it.
