.SH DESCRIPTION
|
|
The Cdk label widget creates a pop-up label window. The following are functions
|
|
which create or manipulate the Cdk label widget.
|
|
|
|
.SH AVAILABLE FUNCTIONS
|
|
CDKLABEL *newCDKLabel (CDKSCREEN *\f2screen\f1, int \f2xpos\f1, int \f2ypos\f1, char **\f2message\f1, int \f2messageLines\f1, boolean \f2box\f1, boolean \f2shadow\f1);
|
|
.RS 3
|
|
This function creates a pointer to a label 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 \f2message\f1 parameter is the message to be displayed in the window. The
|
|
message can accept the full compliment of the standard Cdk display format
|
|
commands. To learn more about this read the \f4cdk_display\f1 manual page.
|
|
The parameter \f2rows\f1 is the number of message rows that were passed in
|
|
on the \f2message\f1 parameter. The \f2box\f1 parameter states whether the
|
|
widget will be drawn with a box around it or not. 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.

This function allows the user to change the contents of the label widget.
|
|
The parameters are the same as the \f4newCDKLabel\f1.

.RS 3

This returns the contents of the label widget. The parameter \f2messageLines\f1
|
|
is an integer pointer which will be given the number of messageLines passed
|
|
back.

.RE
|
|
|
|
void setCDKLabelBackgroundColor (CDKLABEL *\f2label\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 moveCDKLabel (CDKLABEL *\f2label\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.
