.\" The -*- nroff -*- definitions below are for supplemental macros used
.\" in Tcl/Tk manual entries.
.\"
.\" .AP type name in/out ?indent?
.\"	Start paragraph describing an argument to a library procedure.
.\"	type is type of argument (int, etc.), in/out is either "in", "out",
.\"	or "in/out" to describe whether procedure reads or modifies arg,
.\"	and indent is equivalent to second arg of .IP (shouldn't ever be
.\"	needed;  use .AS below instead)
.\"
.\" .AS ?type? ?name?
.\"	Give maximum sizes of arguments for setting tab stops.  Type and
.\"	name are examples of largest possible arguments that will be passed
.\"	to .AP later.  If args are omitted, default tab stops are used.
.\"
.\" .BS
.\"	Start box enclosure.  From here until next .BE, everything will be
.\"	enclosed in one large box.
.\"
.\" .BE
.\"	End of box enclosure.
.\"
.\" .CS
.\"	Begin code excerpt.
.\"
.\" .CE
.\"	End code excerpt.
.\"
.\" .VS ?version? ?br?
.\"	Begin vertical sidebar, for use in marking newly-changed parts
.\"	of man pages.  The first argument is ignored and used for recording
.\"	the version when the .VS was added, so that the sidebars can be
.\"	found and removed when they reach a certain age.  If another argument
.\"	is present, then a line break is forced before starting the sidebar.
.\"
.\" .VE
.\"	End of vertical sidebar.
.\"
.\" .DS
.\"	Begin an indented unfilled display.
.\"
.\" .DE
.\"	End of indented unfilled display.
.\"
.\" .SO ?manpage?
.\"	Start of list of standard options for a Tk widget. The manpage
.\"	argument defines where to look up the standard options; if
.\"	omitted, defaults to "options". The options follow on successive
.\"	lines, in three columns separated by tabs.
.\"
.\" .SE
.\"	End of list of standard options for a Tk widget.
.\"
.\" .OP cmdName dbName dbClass
.\"	Start of description of a specific option.  cmdName gives the
.\"	option's name as specified in the class command, dbName gives
.\"	the option's name in the option database, and dbClass gives
.\"	the option's class in the option database.
.\"
.\" .UL arg1 arg2
.\"	Print arg1 underlined, then print arg2 normally.
.\"
.\" .QW arg1 ?arg2?
.\"	Print arg1 in quotes, then arg2 normally (for trailing punctuation).
.\"
.\" .PQ arg1 ?arg2?
.\"	Print an open parenthesis, arg1 in quotes, then arg2 normally
.\"	(for trailing punctuation) and then a closing parenthesis.

.SH NAME
autoscroll \- Provides for a scrollbar to automatically mapped and unmapped as needed
.SH SYNOPSIS

.SH 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\&.
.PP
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\&.
.PP
This package may be used on any scrollbar-like widget
as long as it supports the \fBset\fR subcommand in the same
style as scrollbar\&. If the \fBset\fR subcommand is not used
then this package will have no effect\&.
.PP
.TP
\fB::autoscroll::autoscroll\fR \fIscrollbar\fR
Arranges for the already existing scrollbar \fBscrollbar\fR
to be mapped and unmapped as needed\&.
.TP
\fB::autoscroll::unautoscroll\fR \fIscrollbar\fR
Returns the named scrollbar to its original static state\&.
.TP
\fB::autoscroll::wrap\fR
Arranges for all scrollbars created after this command is run
to be automatically mapped and unmapped as needed\&.
.TP
\fB::autoscroll::unwrap\fR
Turns off the automatic autoscrolling of all new scrollbars\&.
Does not effect existing scrollbars
