NAME

DESCRIPTION
       This  package allows scrollbars to be mapped and unmapped as needed depending on the size and content
       of the scrollbars scrolled widget. The scrollbar must be managed by either pack or grid, other geome-try geometry
       try managers are not supported.

       When managed by pack, any geometry changes made in the scrollbars parent between the time a scrollbar
       is unmapped, and when it is mapped will be lost. It is an error to destroy any of the scrollbars sib-lings siblings
       lings  while the scrollbar is unmapped. When managed by grid, if anything becomes gridded in the same
       row and column the scrollbar occupied it will be replaced by the scrollbar when remapped.

       This package may be used on any scrollbar-like widget as long as it supports the  set  subcommand  in
       the same style as scrollbar. If the set subcommand is not used then this package will have no effect.


       ::autoscroll::autoscroll scrollbar
              Arranges for the already existing scrollbar scrollbar to be mapped and unmapped as needed.

       ::autoscroll::unautoscroll scrollbar
              Returns the named scrollbar to its original static state.

       ::autoscroll::wrap
              Arranges for all scrollbars created after this command is run to be automatically  mapped  and
              unmapped as needed.

       ::autoscroll::unwrap
              Turns off the automatic autoscrolling of all new scrollbars.  Does not effect existing scroll-bars scrollbars
              bars


       text .t -yscrollcommand ".scrolly set"
       scrollbar .scrolly -orient v -command ".t yview"
       pack .scrolly -side right -fill y
       pack .t -side left -fill both -expand 1
       ::autoscroll::autoscroll .scrolly
