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
