The background of the rectangular area where the string is being drawn will be filled with the receiver's background color. @param string the string to be drawn @param x the x coordinate of the top left corner of the rectangular area where the string is to be drawn @param y the y coordinate of the top left corner of the rectangular area where the string is to be drawn @exception IllegalArgumentException
- ERROR_NULL_ARGUMENT - if the string is null
@exception SWTException
- ERROR_GRAPHIC_DISPOSED - if the receiver has been disposed
