DESCRIPTION

27       This package allows scrollbars to be  mapped  and  unmapped  as  needed
28       depending  on  the  size and content of the scrollbars scrolled widget.
29       The scrollbar must be managed by either pack or  grid,  other  geometry
30       managers are not supported.
31
32       When  managed by pack, any geometry changes made in the scrollbars par‐
33       ent between the time a scrollbar is unmapped, and  when  it  is  mapped
34       will  be lost. It is an error to destroy any of the scrollbars siblings
35       while the scrollbar is unmapped. When  managed  by  grid,  if  anything
36       becomes  gridded  in  the same row and column the scrollbar occupied it
37       will be replaced by the scrollbar when remapped.
38
39       This package may be used on any scrollbar-like widget  as  long  as  it
40       supports  the set subcommand in the same style as scrollbar. If the set
41       subcommand is not used then this package will have no effect.
42
43       ::autoscroll::autoscroll scrollbar
44              Arranges for the already  existing  scrollbar  scrollbar  to  be
45              mapped and unmapped as needed.
46
47       ::autoscroll::unautoscroll scrollbar
48              Returns the named scrollbar to its original static state.
49
50       ::autoscroll::wrap
51              Arranges for all scrollbars created after this command is run to
52              be automatically mapped and unmapped as needed.
53
54       ::autoscroll::unwrap
55              Turns off the automatic autoscrolling  of  all  new  scrollbars.
56              Does not effect existing scrollbars
