-/**
- * The filetreeview offers a treeview on the file system which behaves like
- * a QTreeView showing files and/or directories in the file system.
- *
- * KFileTreeView is able to handle more than one URL, represented by
- * KFileTreeBranch.
- *
- * Typical usage:
- * 1. create a KFileTreeView fitting in your layout and add columns to it
- * 2. call addBranch to create one or more branches
- * 3. retrieve the root item with KFileTreeBranch::root() and set it open
- * if desired. That starts the listing.
