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 message- Lines 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 wid- get. 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. 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 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 re- turned. positionCDKLabel allows the user to move the widget around the screen via the cur- sor/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 attri- bute 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 char- acter. 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.
