-- | Packing parameters of a widget
--
-- * The 'Packing' parameter determines how the child behaves in the horizontal
-- or vertical way in an 'Graphics.UI.Gtk.Layout.HBox' or
-- 'Graphics.UI.Gtk.Layout.VBox', respectively. 'PackNatural'
-- means the child is as big as it requests. It will stay at the start or
-- end of a 'Graphics.UI.Gtk.Layout.Box' if there is more space available.
-- All children packed with 'PackRepel' will be padded on both sides with
-- additional space. 'PackGrow' will increase the size of a widget so that it
-- covers the available space. A menu bar, for instance, should always
-- stay at the top of a window and should only occupy as little space
-- as possible. Hence it should be packed at the start of a
-- 'Graphics.UI.Gtk.Layout.VBox' with
-- the packing option 'PackNatural'. The working area of a window
-- (e.g. the text area in an editor) should expand when the window is
-- resized. Here the packing option 'PackGrow' is the right choice and
-- it is irrelevant whether the main area is inserted at the start or
-- the end of a box. Finally 'PackRepel' is most useful in a window
-- where no widget can make use of excess space. Examples include a
-- dialog box without list boxes or text fields.
