+ * The filetreeview offers a treeview on the file system which behaves like

+ *
+ * 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.
