I'm using a modified version of the memory saving technique presented in the
tutorial to print a huge table out. I run the fitsPage code and it says it
fits the page, so I continue on. The next line says it does not fit, so I
delete the row, print the table, and then say newPage. The output is such
that I get the table printed, a line of the table on the next page, and THEN
a table break. Could this be a bug in fitsPage?
Here's the code:
private void renderGenericTableElement ( ITableElement table,
java.util.List headers, java.util.List content, TableProperties properties,
Vector annotations )
throws DocumentException, InterruptedException
{
// Title
String title = table.getTitle() ;
// If there are no headers or content, then the table is presumed to be
blank. Simply
// Return the title, if any.
if ( null == headers && null == content )
{
if ( null == title )
return ;
Paragraph p = new Paragraph ( title, TABLE_TITLE2_FONT ) ;
addAnnotations(p, annotations) ;
iTextDoc.add(p);
return ;
}
PdfPTable rendering = startGenericTable ( headers, title, properties,
annotations, true ) ;
// Start adding content. Break on page boundaries for memory
management.
int contentSize = content.size() ;
int rowsDrawn = 0 ;
for ( int i = 0 ; i < contentSize ; i++ )
{
addGenericRow ( rendering, (java.util.List)content.get(i),
properties,
i ) ;
// Start a new page if it won't fit
if ( ! writer.fitsPage(rendering) )
{
// If the table has minimumRowsBeforePageBreak set,
then check to see if
the
// line count is greater than the keep together. If
it does, and the
// number of lines drawn is less than the keep
together, break the
// page.
if ( properties.minimumRowsBeforePageBreak > 0
&& rowsDrawn <
properties.minimumRowsBeforePageBreak )
{
iTextDoc.newPage() ;
if ( ! writer.fitsPage(rendering) )
{
// If it still doesn't fit the page,
delete the last line
rendering.deleteLastRow() ;
i-- ;
iTextDoc.add(rendering);
iTextDoc.newPage() ;
rendering = startGenericTable(headers,
title, properties, null,
false);
rowsDrawn = 0 ;
}
}
else
{
// No keep together, end the page.
rendering.deleteLastRow();
i--;
iTextDoc.add (rendering);
iTextDoc.newPage();
rendering = startGenericTable ( headers,
title, properties, null,
false ) ;
rowsDrawn = 0 ;
}
}
rowsDrawn++ ;
}
iTextDoc.add(rendering);
}
The startGenericTable method creates a new table. The addGenericRow code
creates a new row's worth of cells from our data format.
Any thoughts?
Thanks,
Bill

The changes will only show after open() and newPage(). The content has
nothing to do with it.
