       Cdk  provides  functions  to  use  a  large number of predefined curses
       widgets.  To use the Cdk widgets the header file cdk.h must be included
       in the source.

       The widgets available from Cdk are listed below.

       The rest of the manual pages describe supporting functions:

               Manual Page Name   Description
               cdk_binding (3)    Outlines   how   to   create   user
                                  definable key bindings.
               cdk_display (3)    Shows how to  add  special  display
                                  attributes,       colors,       and
                                  justification into a widget.
               cdk_draw (3)       Outlines functions used for drawing
                                  text and lines.
               cdk_screen (3)     Demonstrates  the  use  of  screens
                                  within Cdk.

               cdk_misc (3)       Outlines  miscellaneous   functions
                                  provided with the Cdk library.
               cdk_process (3)    Demonstrates  the  use  of the pre-
                                  and post-process function class.


       Cdk is a library of functions  which  allow  a  programmer  to  quickly
       create  a  full  screen interactive program with ease.  The Cdk widgets
       support the following features:

       · Ncurses library.
            Instead of  using  the  standard  curses  library,  Cdk  can  take
            advantage  of  the  colors that Ncurses provides.  To learn how to
            take advantage of Cdk’s color capabilities, see cdk_display (3).

       · Key Bindings.
            Individual keys can be overridden with a callback.   The  callback
            is  set  up using the bindCDKObject function.  To learn more about
            this see cdk_binding (3).

       · Pre and Post Processing.
            Certain widgets allow the user to  trap  a  character  before  and
            after  the  character has been applied to the widget.  This allows
            programmers to ‘filter’ character input.  To learn more about this
            see cdk_process (3).

       · Self Test Widgets.
            With  the  use  of  the  inject  function  class  and the activate
            function, programmers can have the widgets test themselves.   This
            allows  the  programmer  to  perform  automated  tests  on a final

       · Special Display Formats
            There are special character format commands that can  be  inserted
            into  any  string  in  Cdk  and  the contents will get mapped to a
            chtype (see the curses manual  page)  with  character  attributes.
            This  allows  the  programmer  to  insert  format  types  on  each
            character if they wish.

       · The Ability To Build Predefined Screens
            Widgets can be associated to any given screen.  If there  is  more
            than  one  screen defined, then Cdk has the ability to "flip" from
            one screen to another with ease.  See the cdk_screen  manual  page
            for more details.


       All  of  the  widgets  have  a member of the structure called exitType.
       This member states how the widget exited.  There are  three  values  in
       which to check for, they are as follows:

              |Value            | Meaning                             |
              |vNORMAL          | This   means   the   widget  exited |
              |                 | normally.  This value is  set  when |
              |                 | the  widget is given the characters |
              |                 | TAB or RETURN.                      |
              |vEARLY_EXIT      | This means the widget exited early. |
              |                 | This  value  is set when characters |
              |                 | such as TAB or RETURN are  injected |
              |                 | into    the    widget    via    the |
              |                 | injectCDKXXX   function   and   the |
              |                 | character  injected  does  not exit |
              |                 | the widget.                         |
              |vESCAPE_HIT      | This  value  states  the  user  hit |
              |                 | ESCAPE to leave the widget.         |
              |vNEVER_ACTIVATED | This  is  the  initial state of the |
              |                 | value.  This means that the  widget |
              |                 | has not been activated.             |
