NAME    [Toc]    [Back]

          Cdk - Curses Development Kit

SYNOPSIS    [Toc]    [Back]

       cc [ flag ... ] file ...  -lcdk [ library ... ]

       #include <cdk.h>

       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.

DESCRIPTION    [Toc]    [Back]

       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:

       o 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,
 read the cdk_display manual page.

       o Key Bindings.
            Individual keys can be overridden with  a  call-back.
            The call-back is set up using the bindCDKObject function.
 To learn more about this read  the  cdk_binding
            manual page.

       o 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  read  the
            cdk_process manual page.

       o 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 program.

       o 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.

       o 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


       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 are injected into the
                           widget via the injectCDKXXX function and the
                           character injected does not exit the widget.
                           (ie: TAB or RETURN)
          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.

NOTES    [Toc]    [Back]

       The header file <cdk.h> automatically includes the  header
       files   <curses.h>,   <stdlib.h>,  <string.h>,  <ctype.h>,
       <unistd.h>,  <dirent.h>,  <time.h>,  <errno.h>,   <pwd.h>,
       <grp.h>,  <sys/stat.h>, and <sys/types.h>.  The <curses.h>
       header file includes <stdio.h> and <unctrl.h>.

       If  you  have  Ncurses  installed  on  your  machine   add
       -DNCURSES  to  the  compile  line  to  include the Ncurses
       header files instead.
