DESCRIPTION

       The  Cdk marquee widget creates a pop-up marquee window.  The follow-
       ing functions create or manipulate the Cdk marquee widget.

AVAILABLE FUNCTIONS

       activateCDKMarquee
            activates the marquee widget.

            o   The marquee parameter is a pointer to a defined marquee wid-
                get.

            o   The  delay  parameter  states how long to wait between move-
                ments.  This value is highly dependent on each  machine  the
                program runs on.

            o   The  repeat value tells the marquee widget how many times to
                display the given message.

            o   The box option draws the widget with or without a box.  This
                function  returns -1 if the message passed is NULL, 0 other-
                wise.

       deactivateCDKMarquee
            deactivates the marquee widget.

       destroyCDKMarquee
            removes the widget from the screen and frees memory  the  object
            used.

       drawCDKMarquee
            draws the marquee widget on the screen.  If the box parameter is
            true, the widget is drawn with a box.

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

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

       moveCDKMarquee
            moves the given widget to the given position.

            o   The  parameters  xpos  and  ypos are the new position of the
                widget.

            o   The parameter xpos may be an integer or one of  the  pre-de-
                fined values TOP, BOTTOM, and CENTER.

            o   The  parameter  ypos may be an integer or one of the pre-de-
                fined values LEFT, RIGHT, and CENTER.

            o   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).

            o   The  final parameter refresh is a boolean value which states
                whether the widget will get refreshed after the move.

       newCDKMarquee
            creates a marquee widget and returns a pointer to  it.   Parame-
            ters:

            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  val-
                 ues LEFT, RIGHT, and CENTER.

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

            width
                 controls the width of the field.  If you provide a value of
                 zero for the width,  the  widget  uses  the  width  of  the
                 screen.   If  a negative value is provided, then the widget
                 uses the width of the screen less the value provided.

            shadow
                 turns the shadow on or off around this widget.

            If the widget could not be created then a NULL  pointer  is  re-
            turned.

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

       setCDKMarqueeBackgroundAttrib
            sets the background attribute of the widget.  The parameter  at-
            tribute is a curses attribute, e.g., A_BOLD.

       setCDKMarqueeBackgroundColor
            sets the background color of the widget.  The parameter color is
            in the format of the Cdk format strings.  For  more  information
            see cdk_display(3).

       setCDKMarqueeBox
            sets whether the widget will be drawn with a box around it.

       setCDKMarqueeBoxAttribute
            sets the attribute of the box.

       setCDKMarqueeHorizontalChar
            sets  the  horizontal drawing character for the box to the given
            character.

       setCDKMarqueeLLChar
            sets the lower left hand corner of the widget's box to the given
            character.

       setCDKMarqueeLRChar
            sets  the  lower  right  hand  corner of the widget's box to the
            given character.

       setCDKMarqueeULChar
            sets the upper left hand corner of the widget's box to the given
            character.

       setCDKMarqueeURChar
            sets  the  upper  right  hand  corner of the widget's box to the
            given character.

       setCDKMarqueeVerticalChar
            sets the vertical drawing character for the  box  to  the  given
            character.
