The Cdk marquee widget creates a pop-up marquee window.
|
||
|
|
The following functions create or manipulate the Cdk marquee widget.
|
||
|
|
.SH AVAILABLE FUNCTIONS
|
||
|
|
.TP 5
|
||
|
|
.B activateCDKMarquee
|
||
|
|
activates the marquee widget.
|
||
|
|
.RS
|
||
|
|
.bP
|
||
|
|
The \fBmarquee\fR parameter is a
|
||
|
|
pointer to a defined marquee widget.
|
||
|
|
.bP
|
||
|
|
The \fBdelay\fR parameter states how long
|
||
|
|
to wait between movements.
|
||
|
|
This value is highly dependent on each machine the
|
||
|
|
program runs on.
|
||
|
|
.bP
|
||
|
|
The \fBrepeat\fR value tells the marquee widget how many times
|
||
|
|
to display the given message.
|
||
|
|
.bP
|
||
|
|
The \fBbox\fR option draws the widget with or
|
||
|
|
without a box.
|
||
|
|
This function returns -1 if the message passed is \fINULL\fR,
|
||
|
|
0 otherwise.
|
||
|
|
.RE
|
||
|
|
.TP 5
|
||
|
|
.B deactivateCDKMarquee
|
||
|
|
deactivates the marquee widget.
|
||
|
|
.TP 5
|
||
|
|
.B destroyCDKMarquee
|
||
|
|
removes the widget from the screen and frees memory the object used.
|
||
|
|
.TP 5
|
||
|
|
.B drawCDKMarquee
|
||
|
|
draws the marquee widget on the screen.
|
||
|
|
If the \fBbox\fR parameter is true, the widget is drawn with a box.
|
||
|
|
.TP 5
|
||
|
|
.B eraseCDKMarquee
|
||
|
|
removes the widget from the screen.
|
||
|
|
This does \fINOT\fR destroy the widget.
|
||
|
|
.TP 5
|
||
|
|
.B getCDKMarqueeBox
|
||
|
|
returns true if the widget will be drawn with a box around it.
|
||
|
|
.TP 5
|
||
|
|
.B moveCDKMarquee
|
||
|
|
moves the given widget to the given position.
|
||
|
|
.RS
|
||
|
|
.bP
|
||
|
|
The parameters \fBxpos\fR and \fBypos\fR are the new position of the widget.
|
||
|
|
.bP
|
||
|
|
The parameter \fBxpos\fR may be an integer or one of the pre-defined values
|
||
|
|
\fITOP\fR, \fIBOTTOM\fR, and \fICENTER\fR.
|
||
|
|
.bP
|
||
|
|
The parameter \fBypos\fR may be an integer or one of the pre-defined values \fILEFT\fR,
|
||
|
|
\fIRIGHT\fR, and \fICENTER\fR.
|
||
|
|
.bP
|
||
|
|
The parameter \fBrelative\fR states whether
|
||
|
|
the \fBxpos\fR/\fBypos\fR pair is a relative move or an absolute move.
|
||
|
|
.IP
|
||
|
|
For example, if \fBxpos\fR = 1 and \fBypos\fR = 2 and \fBrelative\fR = \fBTRUE\fR,
|
||
|
|
then the widget would move one row down and two columns right.
|
||
|
|
If the value of \fBrelative\fR was \fBFALSE\fR then the widget would move to the position (1,2).
|
||
|
|
.IP
|
||
|
|
Do not use the values \fITOP\fR, \fIBOTTOM\fR, \fILEFT\fR,
|
||
|
|
\fIRIGHT\fR, or \fICENTER\fR when \fBrelative\fR = \fITRUE\fR.
|
||
|
|
(weird things may happen).
|
||
|
|
.bP
|
||
|
|
The final parameter \fBrefresh\fR is a boolean value which
|
||
|
|
states whether the widget will get refreshed after the move.
