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 much change; 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.
