-- A 'TreeModel' which makes an underlying tree model sortable
--
module Graphics.UI.Gtk.ModelView.TreeModelSort (
-- * Detail
--
-- | The 'TreeModelSort' is a model which implements the 'TreeSortable'
-- interface. It does not hold any data itself, but rather is created with a
-- child model and proxies its data. It has identical rows to its
-- child model, and the changes in the child are propagated. The primary
-- purpose of this model is to provide a way to sort a model without
-- modifying it.
