109 The Cdk label widget creates a pop-up label window. The following
110 functions create or manipulate the Cdk label widget.
111
113 activateCDKLabel
114 obsolete entrypoint which calls drawCDKLabel.
115 destroyCDKLabel
117 removes the widget from the screen and frees memory the object
118 used.
119 drawCDKLabel
121 draws the label widget on the screen. If the box parameter is
122 true, the widget is drawn with a box.
123 eraseCDKLabel
125 removes the widget from the screen. This does NOT destroy the
126 widget.
127 getCDKLabelBox
129 returns true if the widget will be drawn with a box around it.
130 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 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 newCDKLabel
152 creates a label widget and returns a pointer to it. Parameters:
153 screen
155 is the screen you wish this widget to be placed in.
156 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 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.
164 message
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 [4m(3).
169 rows is the number of message rows that were passed in the message
171 parameter.
172 box is true if widget should be drawn with a box around it.
174 shadow
176 turns the shadow on or off around this widget.

179 returned.

191 attribute is a curses attribute, e.g., A_BOLD.
