module Graphics.UI.Gtk.Misc.Arrow (
-- * Detail
-- 
-- | 'Arrow' should be used to draw simple arrows that need to point in one of
-- the four cardinal directions (up, down, left, or right). The style of the
-- arrow can be one of shadow in, shadow out, etched in, or etched out. Note
-- that these directions and style types may be ammended in versions of Gtk to
-- come.
--
-- 'Arrow' will fill any space alloted to it, but since it is inherited from
-- 'Misc', it can be padded and\/or aligned, to fill exactly the space the
-- programmer desires.
--
-- Arrows are created with a call to 'arrowNew'. The direction or style of
-- an arrow can be changed after creation by using 'arrowSet'.
