needed
SYNOPSIS¶

package require
autoscroll ?1.1?
::autoscroll::autoscroll scrollbar
::autoscroll::unautoscroll scrollbar
::autoscroll::wrap
::autoscroll::unwrap
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 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 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.
