khim - Provides key bindings for entering international characters
    on a keyboard that does not support them

This package provides a set of key bindings to allow a user to
    enter arbitrary characters on a keyboard that does not support them. It
    works by designating some seldom-used key of the keyboard as a
    "Compose" key (this key is distinct from any key so labeled, and
    is often "Pause," "F12" or "L2"), and having
    the "Compose" key, followed by a two-key sequence, have the effect
    of inserting some character in a widget. In addition, the
    "Compose" key, when struck twice in succession, brings up a dialog
    containing a Unicode character map, allowing arbitrary characters to be
    inserted.


The vast bulk of the package's functionality is implemented in a
    single bindtag, KHIM. An application can request that any text or
    entry widget use the package to allow for entry of arbitrary characters by
    placing this binding tag ahead of the Text or Entry binding
    tag for the widget:




text .t -width 80 -height 24
bindtags .t {.t KHIM Text . all}




Note that the KHIM tag must precede the Text or Entry class
  binding, or the package will not function correctly.







In addition to commands supporting the KHIM binding tag, the
    following commands are exported from the package:



  
::khim::getOptions path

  
Posts a top-level modal dialog with the path name path that prompts
      the user for KHIM options. The user is allowed to reconfigure the key
      sequences for the "Compose" key, change the choice of key to use
      for the "Compose" function, and enable/disable the KHIM key
      bindings entirely.

  
::khim::getConfig

  
Returns a Tcl script that restores the current configuration of KHIM: the
      enabled/disabled state, the choice of "Compose" key, and the key
      sequences that may be composed. This script is designed to be saved to a
      configuration file for use in a subsequent invocation of the same
      application:






# Save KHIM configuration
set f [open ~/.khimrc w]
puts $f [::khim::getConfig]
close $f
# Restore KHIM configuration
source ~/.khimrc






  
::khim::setConfig version enabled compose
    map

  
Restores an earlier saved configuration. Few, if any, applications will
      call this command in any other way than to evaluate it as returned from
      ::khim::getConfig.

  
::khim::showHelp path

  
Displays a top-level dialog giving user-level help for KHIM; the dialog
      will have the path name path.










Programmers who wish to make KHIM available in a
    non-English-speaking locale may do so by providing a .msg file with
    the appropriate localised text. The catalog requires the following
  messages:



  

  
Text that will appear on the "Apply" button in the dialog that
      sets KHIM options.

  

  
Text that will appear on the "Cancel" button in several
    dialogs.

  

  
Text that will appear on the "Change" button, which alters the
      binding of a pair of composed characters (creating or replacing as
      appropriate).

  

  
Text that will appear on the label of the entry widget that accepts a
      character resulting from a composed sequence.

  
{Compose Key}

  
Window title for a dialog that prompts the user to strike the key that
      will be used for the "Compose" key.

  
{Compose key:}

  
Label that identifies a component showing the "Compose" key
      choice in the KHIM options dialog.

  
{Composed sequence must be two characters long}

  
Error message that is displayed if the user attempts to define a
      "Compose" sequence that is shorter or longer than two
      characters.

  

  
Text for a button that deletes a "Compose" sequence.

  

  
Text for a button that displays the KHIM user help dialog.

  

  
Complete text for the user-level help for KHIM. Refer to
      "en.msg" for the English-language version of the
    help.

  
{Input key sequence}

  
Text for a label of the entry widget that prompts the user for a
      two-character sequence to use with the "Compose" key.

  
{Insert Character}

  
Window title of the dialog box that displays a Unicode character map and
      prompts the user to select a character to insert.

  
{Key sequences}

  
Text for a label at the head of a listbox showing the composed sequences
      that are currently bound.

  
{KHIM Controls}

  
Window title for the dialog box that prompts for KHIM settings.

  
{KHIM Help}

  
Window title for the window that display help text for KHIM.

  

  
Label for the OK button on several dialogs.

  

  
Label for a spinbox that prompts the user for a Unicode code page
    number.

  

  
A message, which should be composed in short lines, prompting the user to
      press the key that will become the "Compose" key in KHIM.

  

  
Text for a button that brings up the character map to select the character
      to which a composed sequence binds.

  
{Use KHIM}

  
Text for a checkbutton that asks whether the user wishes to use KHIM to
      manage composed key sequences.










KHIM was originally inspired by the key bindings that Brent Welch
    developed for the 'sedit' editor used in the 'exmh' mail user agent. The
    code for KHIM is entirely separate from that for 'sedit'.
