  13  Whenever a page break condition is met, the method is called, and the break is issued or not
  14  depending on the returned value. The default implementation returns a value according to the
  15  mode selected by SetAutoPageBreak().
  16  <BR>
  17  This method is called automatically and should not be called directly by the application.
  18  <H4 CLASS='st'>Example</H4>
  19  The method is overriden in an inherited class in order to obtain a 3 column layout:
