Also, for the QTreeView, it might even be beneficial to make your model load hierarchies on demand as opposed to an exhaustive walk of the whole tree. So each time you expand a node, thats when you find the children. Unless of course you actually run an 'expand all' type operation. And I agree with Judah about subclassing a QStandardItem as some kind of NodeItem that holds your paths and important metadata.
