DESCRIPTION

109       The  Cdk  label  widget  creates  a pop-up label window.  The following
110       functions create or manipulate the Cdk label widget.
111

AVAILABLE FUNCTIONS

113       activateCDKLabel
114            obsolete entrypoint which calls drawCDKLabel.
115
116       destroyCDKLabel
117            removes the widget from the screen and  frees  memory  the  object
118            used.
119
120       drawCDKLabel
121            draws  the  label  widget  on the screen.  If the box parameter is
122            true, the widget is drawn with a box.
123
124       eraseCDKLabel
125            removes the widget from the screen.  This  does  NOT  destroy  the
126            widget.
127
128       getCDKLabelBox
129            returns true if the widget will be drawn with a box around it.
130
131       getCDKLabelMessage
132            returns  the contents of the label widget.  The parameter message‐
133            Lines points to the location which will be  given  the  number  of
134            message-lines.
135
136       moveCDKLabel
137            moves the given widget to the given position.  The parameters xpos
138            and ypos are the new position of the widget.  The  parameter  xpos
139            may  be  an  integer or one of the pre-defined values TOP, BOTTOM,
140            and CENTER.  The parameter ypos may be an integer or  one  of  the
141            pre-defined  values  LEFT, RIGHT, and CENTER.  The parameter rela‐
142            tive states whether the xpos/ypos pair is a relative  move  or  an
143            absolute move.  For example, if xpos = 1 and ypos = 2 and relative
144            = TRUE, then the widget would move one row down  and  two  columns
145            right.   If  the value of relative was FALSE then the widget would
146            move to the position (1,2).  Do not use the  values  TOP,  BOTTOM,
147            LEFT,  RIGHT,  or  CENTER when relative = TRUE.  (weird things may
148            happen).  The final parameter refresh is  a  boolean  value  which
149            states whether the widget will get refreshed after the move.
150
151       newCDKLabel
152            creates a label widget and returns a pointer to it.  Parameters:
153
154            screen
155                 is the screen you wish this widget to be placed in.
156
157            xpos controls  the  placement  of  the object along the horizontal
158                 axis.  It may be an integer or one of the pre-defined  values
159                 LEFT, RIGHT, and CENTER.
160
161            ypos controls the placement of the object along the vertical axis.
162                 It may be an integer or one of the  pre-defined  values  TOP,
163                 BOTTOM, and CENTER.

166                 is the message to be displayed in the window.  It may contain
167                 any of the standard Cdk display format  commands.   To  learn
168                 more about this see cdk_display (3).
169
170            rows is the number of message rows that were passed in the message
171                 parameter.
