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.
