[Demo]

+The key method used is AcceptPageBreak(). 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. +
+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. + + -- cgit
