.TH "history" 3tk 0\&.1 tklib "Provides a history for Entry widgets"
.\" 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 DESCRIPTION
This package provides a convenient history mechanism for Entry widgets\&.
The history may be accessed with the up and down arrow keys\&.
.PP
.TP
\fB::history::init\fR \fIpathName\fR ?length?
Arranges to remember the history of the named Entry widget\&. An optional length
determines the number of history entries to keep\&. This may be changed later
with \fB::history::configure\fR\&. History entries must be added with the
\fB::history::add\fR command before they can be seen\&.
.TP
\fB::history::remove\fR \fIpathName\fR
Forgets all history entries for the Entry \fIpathName\fR and removes the history
bindings\&.
.TP
\fB::history::add\fR \fIpathName\fR \fItext\fR
This command is used to add history entries to an Entry that has previously had
\fB::history::init\fR called on it\&. This command should be called from your Entry
handler with the contents of the entry (or whatever you wish to add to the history)\&.
.TP
\fB::history::get\fR \fIpathName\fR
This command returns a list containing the history entries for the Entry \fIpathName\fR
.TP
\fB::history::clear\fR \fIpathName\fR
This command clears the history list for the named Entry\&.
.TP
\fB::history::configure\fR \fIpathName\fR \fIoption\fR ?value?
This command queries or sets configuration options\&. Currently the options recognized
are \fIlength\fR and \fIalert\fR\&. Setting the length determines the number of history entries to keep for
the named Entry\&. Alert specifies the command to run when the user reaches the end of the history, it defaults to
.TP
bell
\&. Although configure requires a \fIpathName\fR argument, the setting for alert is global and the path is ignored\&.
