  • Offset is an integer that show how many characters are hidden.
  • FieldLength is the length of the display box. It decide the maximum number of character you want to display.
  • CurorPos is the cursor position within the display box. For example, if your FieldLength is 10, your cursor position can be from 1-10.
  • Max str length is used when FieldLength is 0. It decide the length of your str so that it will fit on the screen(with no wrap).
