module Graphics.UI.Gtk.Abstract.Misc (
-- * Detail
-- 
-- | The 'Misc' widget is an abstract widget which is not useful itself, but
-- is used to derive subclasses which have alignment and padding attributes.
--
-- The horizontal and vertical padding attributes allows extra space to be
-- added around the widget.
--
-- The horizontal and vertical alignment attributes enable the widget to be
-- positioned within its allocated area. Note that if the widget is added to a
-- container in such a way that it expands automatically to fill its allocated
-- area, the alignment settings will not alter the widgets position.
