Hi,
I've run into a bit of trouble with headers and footers. I started off
using setHeader(HeaderFooter), then saw that that was apparently 'old
functionality' and that I should be using page events. So, I created a
bare-bones event class based explicitly on the example from EndPage.java in
the iText tutorial (here:
http://itextdocs.lowagie.com/tutorial/directcontent/pageevents/index.html ).
I literally just copied the onEndPage method from that one and put it into
my new class; it's the only method in the class. My problem is that the
event is being called and handled by the class, but no output is being
written by that method (the rest of the output is OK). Here's what I'm
doing (abstracting out unimportant stuff):
Java code-ish:
/* assuming OutputStream out is passed in to this, the document generator;
* out is the OutputStream from the HttpServletResponse */
Document document = new Document([page size], [margins all set to 0]);
PdfWriter writer = PdfWriter.getInstance(document, out);
writer.setPageEvent(new myPageEventHandler()); //this has the onEndPage from
EndPage.java
document.open();
/* from here is contained in a bean which renders its data as a table;
document is passed in */
document.newPage();
Phrase titleText = new Phrase("This is a bold title that is NOT to be a
header");
document.add(titleText);
PdfPTable table = new PdfPTable(3);
table.setTotalWidth([page size.width * a margin ratio]);
table.setLockedWidth(true);
PdfPCell cell = null;
/* assume that this could be hundreds or thousands of rows long */
for(int i = 0; i<9999; i++) {
cell = new PdfPCell(new Phrase("celldata " + i));
/* cell modifications, like border width, rowspan, etc. */
table.addCell(cell);
}
document.add(table);
/* now this is performed by the class which calls the bean's method (above)
*/
if(document != null) document.close();
if(out != null) out.close();
//end Java code
I suspect there's something going on with the mixing of the
writeSelectedRows in the onEndPage method; if I replace that line with
document.add(head) etc. I can write to the page, but the problem is that
those don't show up on the first page, just the second page and thereafter.
More to the point, just using document.add doesn't allow me to set the
positioning of the headers and footers. As a final bit of information, I'm
using iText 2.0.5 after upgrading from 1.1.4; I've quashed all other bugs,
but this one is the last one (headers and footers didn't work for me in the
old version either). This is driving me crazy and I'm looking for any help
or advice that can be offered. Thanks!
John Z.
