DESCRIPTION
The Cdk label widget creates a pop-up label window. The following functions create or
manipulate the Cdk label widget.
AVAILABLE FUNCTIONS
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 messageLines points to the
location which will be given the number of message-lines.
moveCDKLabel
moves the given widget to the given position.
• The parameters xpos and ypos are the new position of the widget.
The parameter xpos may be an integer or one of the pre-defined values TOP,
BOTTOM, and CENTER.
The parameter ypos may be an integer or one of the pre-defined values LEFT,
RIGHT, and CENTER.
• 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).
• 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 values 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 values TOP, BOTTOM, and CENTER.
message
is the message to be displayed in the window. It may contain 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 message 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 returned.
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 attribute 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.
