DESCRIPTION

34       This package provides a convenient history mechanism for Entry widgets.
35       The history may be accessed with the up and down arrow keys.
36
37       ::history::init pathName ?length?
38              Arranges to remember the history of the named Entry  widget.  An
39              optional  length  determines  the  number  of history entries to
40              keep. This may be changed later with ::history::configure.  His‐
41              tory  entries  must  be  added  with  the ::history::add command
42              before they can be seen.
43
44       ::history::remove pathName
45              Forgets all history entries for the Entry pathName  and  removes
46              the history bindings.
47
48       ::history::add pathName text
49              This command is used to add history entries to an Entry that has
50              previously had ::history::init called on it. This command should
51              be called from your Entry handler with the contents of the entry
52              (or whatever you wish to add to the history).
53
54       ::history::get pathName
55              This command returns a list containing the history  entries  for
56              the Entry pathName
57
58       ::history::clear pathName
59              This command clears the history list for the named Entry.
60
61       ::history::configure pathName option ?value?
62              This  command  queries  or sets configuration options. Currently
63              the options recognized are length and alert. Setting the  length
64              determines  the  number of history entries to keep for the named
65              Entry. Alert specifies the command to run when the user  reaches
66              the end of the history, it defaults to
67

74
75       proc ProcessEntry {w} {
76           set text [$w get]
77           if {$text == ""} { return }
78           ::history::add $w $text
79           puts $text
80           $w delete 0 end
81       }
