module Graphics.UI.Gtk.Abstract.Bin (
-- * Detail
-- 
-- | The 'Bin' widget is a container with just one child. It is not very
-- useful itself, but it is useful for deriving subclasses, since it provides
-- common code needed for handling a single child widget.
--
-- Many Gtk+ widgets are subclasses of 'Bin', including 'Window', 'Button',
-- 'Frame', 'HandleBox', and 'ScrolledWindow'.
