    -- | The 'HScrollbar' widget is a widget arranged horizontally creating a
    -- scrollbar. See 'Scrollbar' for details on scrollbars. An 'Adjustment'
    -- may be added to handle the adjustment of the scrollbar using
    -- 'hScrollbarNew' or you can use 'hScrollbarNewDefaults' in
    -- which case one will be created for you. See 'Adjustment' for details.
    --
    -- All interesting functions can be found in 'Range', from which it is derived.
