The key method used is <a href='../doc/acceptpagebreak.htm'>AcceptPageBreak()</a>. It allows to accept or not an automatic page

break. By refusing it and altering the margin and current position, the desired column layout

is achieved.

<br>

For the rest, not many changes; two properties have been added to the class to save the current

column number and the position where columns begin, and the MultiCell() call specifies a

6 centimeter width.
