The Cdk label widget creates a pop-up label window. The following
functions create or manipulate the Cdk label widget.
activateCDKLabel
obsolete entrypoint which calls drawCDKLabel.
destroyCDKLabel
removes the widget from the screen and frees memory the object
used.
drawCDKLabel
draws the label widget on the screen. If the box parameter is
true, the widget is drawn with a box.
eraseCDKLabel
removes the widget from the screen. This does NOT destroy the
widget.
getCDKLabelBox
returns true if the widget will be drawn with a box around it.
getCDKLabelMessage
returns the contents of the label widget. The parameter mes-
sageLines points to the location which will be given the number
of message-lines.
moveCDKLabel
moves the given widget to the given position.
o The parameters xpos and ypos are the new position of the
widget.
The parameter xpos may be an integer or one of the pre-de-
fined values TOP, BOTTOM, and CENTER.
The parameter ypos may be an integer or one of the pre-de-
fined values LEFT, RIGHT, and CENTER.
o The parameter relative states whether the xpos/ypos pair is
a relative move or an absolute move.
For example, if xpos = 1 and ypos = 2 and relative = TRUE,
then the widget would move one row down and two columns
right. If the value of relative was FALSE, then the widget
would move to the position (1,2).
Do not use the values TOP, BOTTOM, LEFT, RIGHT, or CENTER
when relative = TRUE. (weird things may happen).
o The final parameter refresh is a boolean value which states
whether the widget will get refreshed after the move.
newCDKLabel
creates a label widget and returns a pointer to it. Parameters:
screen
is the screen you wish this widget to be placed in.
xpos controls the placement of the object along the horizontal
axis. It may be an integer or one of the pre-defined val-
ues LEFT, RIGHT, and CENTER.
ypos controls the placement of the object along the vertical
axis. It may be an integer or one of the pre-defined val-
ues TOP, BOTTOM, and CENTER.
message
is the message to be displayed in the window. It may con-
tain any of the standard Cdk display format commands. To
learn more about this see cdk_display(3).
rows is the number of message rows that were passed in the mes-
sage parameter.
box is true if widget should be drawn with a box around it.
shadow
turns the shadow on or off around this widget.
If the widget could not be created then a NULL pointer is re-
turned.
positionCDKLabel
allows the user to move the widget around the screen via the
cursor/keypad keys. See cdk_position(3) for key bindings.
setCDKLabel
allows the user to change the contents of the label widget. The
parameters are the same as the newCDKLabel.
setCDKLabelBackgroundAttrib
sets the background attribute of the widget. The parameter at-
tribute is a curses attribute, e.g., A_BOLD.
setCDKLabelBackgroundColor
sets the background color of the widget. The parameter color is
in the format of the Cdk format strings. For more information
see cdk_display(3).
setCDKLabelBox
sets whether the widget will be drawn with a box around it.
setCDKLabelBoxAttribute
sets the attribute of the box.
setCDKLabelHorizontalChar
sets the horizontal drawing character for the box to the given
character.
setCDKLabelLLChar
sets the lower left hand corner of the widget's box to the given
character.
setCDKLabelLRChar
sets the lower right hand corner of the widget's box to the
given character.
setCDKLabelMessage
This sets the contents of the label widget.
setCDKLabelULChar
sets the upper left hand corner of the widget's box to the given
character.
setCDKLabelURChar
sets the upper right hand corner of the widget's box to the
given character.
setCDKLabelVerticalChar
sets the vertical drawing character for the box to the given
character.
waitCDKLabel
waits for a user to press a key. The label parameter is the
pointer to a label widget, and key is the key to wait for. If
no specific key is desired, use (char)0.
