-- A widget displaying a single row of a 'TreeModel'
--
-- * Module available since Gtk+ version 2.6
--
module Graphics.UI.Gtk.ModelView.CellView (
-- * Detail
--
-- | A 'CellView' displays a single row of a 'TreeModel', using cell renderers
-- just like 'TreeView'. 'CellView' doesn't support some of the more complex
-- features of 'TreeView', like cell editing and drag and drop.
