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 geometry
managers are not supported.
When managed by pack, any geometry changes made in the scrollbars par-
ent 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 siblings
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 scrollbars
