DESCRIPTION
       This package provides a set of key bindings to allow a user to enter arbitrary characters on  a  key-board keyboard
       board  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 char-acter character
       acter in a widget.  In addition, the "Compose" key, when struck twice in succession, brings up a dia-log dialog
       log 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 applica-tion application
       tion can request that any text or entry widget use the package to allow for entry of arbitrary  char-acters characters
       acters 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.



PROCEDURES
       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.


LOCALISATION
       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:

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

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

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

       Character
              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.

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

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

       HELPTEXT
              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.

       OK     Label for the OK button on several dialogs.

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

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

       Unicode...
              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.


ACKNOWLEDGMENTS
       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'.
