autoscroll — Provides for a scrollbar to automatically mapped and unmapped as needed
package require Tcl
package require autoscroll ?1.1?
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.
