DESCRIPTION
The Cdk marquee widget creates a pop-up marquee window. The following functions create or manipulate the
Cdk marquee widget.
AVAILABLE FUNCTIONS
activateCDKMarquee
activates the marquee widget.
• The marquee parameter is a pointer to a defined marquee widget.
• The delay parameter states how long to wait between movements. This value is highly dependent
on each machine the program runs on.
• The repeat value tells the marquee widget how many times to display the given message.
• The box option draws the widget with or without a box. This function returns -1 if the message
passed is NULL, 0 otherwise.
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.
• 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.
newCDKMarquee
creates a marquee widget and returns a pointer to it. 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 may be an integer or one of
the pre-defined values 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 returned.
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 attribute 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
