QTreeWidget::setModel() - Changing the model of the QTreeWidget is not allowed.

[JeanC]

I don't think you can setModel() on a QTreeWidget, but you can on a QTreeView.

There are 2 ways to use a treeview / listview etc. With the 'simple' QTreeWidget / QListWidget who have their own inner model, or through the model / view classes like for instance QTreeView / QDirModel or other models.

So just use QTreeView in stead of QTreeWidget and you're set.

I thought this was due to my typograhpic error. However it compilied without any warning.
