.SH DESCRIPTION
The Cdk marquee widget creates a pop-up marquee window. The following are
functions which create or manipulate the Cdk marquee widget.
.SH AVAILABLE FUNCTIONS
CDKMARQUEE *newCDKMarquee (CDKSCREEN *\f2screen\f1, int \f2xpos\f1, int \f2ypos\f1, int \f2fieldWidth\f1, boolean \f2shadow\f1);
.RS 3
This function creates a pointer to a marquee widget. The \f2screen\f1 parameter
is the screen you wish this widget to be placed in. The parameter \f2xpos\f1
controls the placement of the object along the horizontal axis. This parameter
can accept an integer value or one of the pre-defined values of \f4LEFT\f1,
\f4RIGHT\f1, and \f4CENTER\f1. The parameter \f2ypos\f1 controls the placement
of the object along the vertical axis. This parameter can accept an integer
value or one of the pre-defined values of \f4TOP\f1, \f4BOTTOM\f1, and \f4CENTER\f1.
The \f2width\f1 parameter state how wide the field is to be. If you provide a
value of zero for the width, the widget will assume the full width of the
screen. If a negative value is provided, then the widget will assume the
full width of the screen minus the value provided. The \f2shadow\f1 parameter
accepts a boolean value to turn the shadow on or off around this widget. If
the widget could not be created then a \f4NULL\f1 pointer is returned.
.RE
int activateCDKMarquee (CDKMARQUEE *\f2marquee\f1, char *\f2message\f1, int \f2delay\f1, int \f2repeat\f1, boolean \f2box\f1);
.RS 3
This function activates the marquee widget. The \f2marquee\f1 parameter is a
pointer to a defined marquee widget. The \f2delay\f1 parameter states how long
to wait between movements. This value is highly dependent on each machine the
program runs on. The \f2repeat\f1 value tells the marquee widget how many times
to display the given message. The \f2box\f1 option draws the widget with or
without a box. This function returns -1 if the message passed is \f4NULL\f1,
0 otherwise.
.RE
void setCDKMarqueeULChar (CDKMARQUEE *\f2marquee\f1, chtype \f2character\f1);
.RS 3
This function sets the upper left hand corner of the widgets box to
the given character.
.RE
void setCDKMarqueeURChar (CDKMARQUEE *\f2marquee\f1, chtype \f2character\f1);
.RS 3
This function sets the upper right hand corner of the widgets box to
the given character.
.RE
void setCDKMarqueeLLChar (CDKMARQUEE *\f2marquee\f1, chtype \f2character\f1);
.RS 3
This function sets the lower left hand corner of the widgets box to
the given character.
.RE
void setCDKMarqueeLRChar (CDKMARQUEE *\f2marquee\f1, chtype \f2character\f1);
.RS 3
This function sets the lower right hand corner of the widgets box to
the given character.
.RE
void setCDKMarqueeVerticalChar (CDKMARQUEE *\f2marquee\f1, chtype \f2character\f1);
.RS 3
This function sets the vertical drawing character for the box to
the given character.
.RE
void setCDKMarqueeHorizontalChar (CDKMARQUEE *\f2marquee\f1, chtype \f2character\f1);
.RS 3
This function sets the horizontal drawing character for the box to
the given character.
.RE
void setCDKMarqueeBoxAttribute (CDKMARQUEE *\f2marquee\f1, chtype \f2attribute\f1);
.RS 3
This function sets the attribute of the box.
.RE
void setCDKMarqueeBackgroundColor (CDKMARQUEE *\f2marquee\f1, char *\f2color\f1);
.RS 3
This sets the background color of the widget. The parameter \f2color\f1
is in the format of the Cdk format strings. To get more information look
at the \f4cdk_display\f1 manual page.
.RE
void moveCDKMarquee (CDKMARQUEE *\f2marquee\f1, int \f2xpos\f1, int \f2ypos\f1, boolean \f2relative\f1, boolean \f2refresh\f1);
.RS 3
This function moves the given widget to the given position. The parameters
\f2xpos\f1 and \f2ypos\f1 is the new position of the widget. The parameter
\f2xpos\f1 can accept an integer value or one of the pre-defined values of
\f4TOP\f1, \f4BOTTOM\f1, and \f4CENTER\f1. The parameter \f2ypos\f1 can
accept an integer value or one of the pre-defined values of \f4LEFT\f1,
\f4RIGHT\f1, and \f4CENTER\f1. The parameter \f2relative\f1 states whether
the \f2xpos\f1/\f2ypos\f1 pair is a relative move or an absolute move. For
example if \f2xpos\f1 = 1 and \f2ypos\f1 = 2 and \f2relative\f1 = \f2TRUE\f1,
then the widget would move one row down and two columns right. If the value
of \f2relative\f1 was \f2FALSE\f1 then the widget would move to the position
(1,2). Do not use the values of \f4TOP\f1, \f4BOTTOM\f1, \f4LEFT\f1,
\f4RIGHT\f1, or \f4CENTER\f1 when \f2relative\f1 = \f4TRUE\f1. (weird things
may happen). The final parameter \f2refresh\f1 is a boolean value which
states whether the widget will get refreshed after the move or not.
.RE
void positionCDKMarquee (CDKMARQUEE *\f2marquee\f1);
.RS 3
This function allows the user to move the widget around the screen via the
cursor/keypad keys. The following key bindings can be used to move the
widget around the screen.

Keypad means that if the keyboard you are using has a keypad, then the
Num-Lock light has to be on in order to use the keys as listed. (The
numeric keys at the top of the keyboard will work as well.)

void drawCDKMarquee (CDKMARQUEE *\f2marquee\f1, boolean \f2box\f1);
.RS 3
This function draws the marquee widget on the screen. The \f2box\f1 option
draws the widget with or without a box.
.RE
void eraseCDKMarquee (CDKMARQUEE *\f2marquee\f1);
.RS 3
This function removes the widget from the screen. This does \f4NOT\f1 destroy
the widget.
.RE
void destroyCDKMarquee (CDKMARQUEE *\f2marquee\f1);
.RS 3
This function removes the widget from the screen and frees up any memory the
object may be using.
