DESCRIPTION

       The  Cdk  buttonbox  widget  creates a buttonbox box with a message and a varied number of
       buttons to choose from.  The following functions create or manipulate  the  Cdk  buttonbox
       box widget.

AVAILABLE FUNCTIONS

       activateCDKButtonbox
            activates  the  buttonbox  widget  and  lets  the user interact with the widget.  The
            parameter buttonbox is a pointer to a non-NULL  buttonbox  widget.   If  the  actions
            parameter  is  passed  with  a  non-NULL  value,  the characters in the array will be
            injected into the widget.  To activate  the  widget  interactively  pass  in  a  NULL
            pointer for actions.  If the character entered into this widget is RETURN or TAB then
            this function will return a value from 0 to the number of  buttons  -1,  representing
            the  button  selected.  It will also set the widget data exitType to vNORMAL.  If the
            character entered into this widget was ESCAPE then the widget will return a value  of
            -1 and the widget data exitType will be set to vESCAPE_HIT.

       destroyCDKButtonbox
            removes the widget from the screen and releases any memory the object used.

       drawCDKButtonbox
            draws  the  buttonbox widget on the screen.  If the box parameter is true, the widget
            is drawn with a box.

       drawCDKButtonboxButtons
            draws the buttons.

       eraseCDKButtonbox
            removes the widget from the screen.  This does NOT destroy the widget.

       getCDKButtonboxBox
            returns true if the widget will be drawn with a box around it.

       getCDKButtonboxButtonCount
            returns the number of buttons in the button box.

       getCDKButtonboxCurrentButton
            returns the current button-number.

       getCDKButtonboxHighlight
            returns the highlight attribute of the widget.

       injectCDKButtonbox
            injects a single character into the widget.  The parameter buttonbox is a pointer  to
            a non-NULL buttonbox widget.  The parameter character is the character to inject into
            the widget.  The return value and side-effect  (setting  the  widget  data  exitType)
            depend upon the injected character:

            RETURN or TAB
                   the  function returns a value ranging from zero to one less than the number of
                   buttons, representing the button selected.  The widget data exitType is set to
                   vNORMAL.

            ESCAPE the  function  returns  -1.   vESCAPE_HIT.  The widget data exitType is set to
                   vESCAPE_HIT.

            Otherwise
                   unless modified by preprocessing, postprocessing or key bindings, the function
                   returns -1.  The widget data exitType is set to vEARLY_EXIT.

       moveCDKButtonbox
            moves  the  given widget to the given position.  The parameters xpos and ypos are the
            new position of the widget.  The parameter xpos may be an integer or one of the  pre-
            defined  values TOP, BOTTOM, and CENTER.  The parameter ypos may be an integer or one
            of the pre-defined values LEFT, RIGHT, and CENTER.   The  parameter  relative  states
            whether  the  xpos/ypos pair is a relative move or an absolute move.  For example, if
            xpos = 1 and ypos = 2 and relative = TRUE, then the widget would move  one  row  down
            and two columns right.  If the value of relative was FALSE then the widget would move
            to the position (1,2).  Do not use the values TOP, BOTTOM,  LEFT,  RIGHT,  or  CENTER
            when  relative  = TRUE.  (weird things may happen).  The final parameter refresh is a
            boolean value which states whether the widget will get refreshed after the move.

       newCDKButtonbox
            creates a pointer to a buttonbox widget.  Parameters:

            screen
                 is the screen you wish this widget to be placed in.

            xpos controls the placement of the object along the horizontal axis.  It  may  be  an
                 integer or one of the pre-defined values LEFT, RIGHT, and CENTER.

            ypos controls  the placement of the object along the vertical axis.  It be an integer
                 value or one of the pre-defined values TOP, BOTTOM, and CENTER.

            height and

            width
                 control the height and width of the widget.

            title
                 is the title of the widget.

            rows is the number of rows of buttons.

            cols sets the number of columns.

            buttons
                 is an array containing the button labels.

            buttonCount
                 is the number of elements in the buttons array.

            highlight

            box  is true if the widget should be drawn with a box around it.

            shadow
                 turns the shadow on or off around this widget.

            If the widget could not be created then a NULL pointer is returned.

       positionCDKButtonbox
            allows the user to move the widget around the screen via the cursor/keypad keys.  See
            cdk_position (3) for key bindings.

       setCDKButtonbox

            function.

       setCDKButtonboxBackgroundAttrib
            sets  the  background  attribute  of the widget.  The parameter attribute is a curses
            attribute, e.g., A_BOLD.

       setCDKButtonboxBackgroundColor

            Cdk format strings.  (See cdk_display).

       setCDKButtonboxBox
            sets true if the widget will be drawn with a box around it.

       setCDKButtonboxPostProcess
            allows  the user to have the widget call a function after the key has been applied to
            the widget.  The parameter function is the callback function.  (See cdk_process).

       setCDKButtonboxPreProcess
            allows the user to have the widget call a function after a key is hit and before  the
            key is applied to the widget.  The parameter function is the callback function.  (See
