I'm sorry to ask something that appears so frequently, but I can't seem to
get it to work. I want to put a large amount of information in the header
on the first page and a smaller amount in each successive page. I've read
all I can find and everyone says 'put it in the onEndPage event'.
I have a class GenerationService that builds my pdf. In it there is a
nested class HeaderManager extends PdfPageEventHelper to manage the
headers. In GenerationService there is a getBigHeader(args) and a
getLittleHeader(args). They work; I've tried Table.setHeaderRows(2) and
PdfPCell headerCell = new PdfPCell(getBigHeader(args));
docTable.addCell(headerCell); as the first lines in the document assembly
process and I get what I want to see. Similarly for getLittleHeader.
My onEndPage event looks like this:
try {
Rectangle page = document.getPageSize();
PdfPTable head = new PdfPTable(4);
if (document.getPageNumber() == 1){
head.addCell(getBigHeader(theCsi, theCert));
} else {
head.addCell(getLittleHeader(theCsi, theCert));
}
System.out.println ("LdCsiHeaderManager:onEndPage:
head.getTotalHeight()=" + head.getTotalHeight());
head.setTotalWidth(page.getWidth() - document.leftMargin() -
document.rightMargin());
head.writeSelectedRows(0, -1, document.leftMargin(),
page.getHeight() - document.topMargin() +
head.getTotalHeight(), writer.getDirectContent());
}
I've pulled out a lot of System.out.println's that I've been using to
instrument the code. I've seen enough to know that the plumbing works; the
events don't start to fire until the document is assembled, and my event
can see global vars outside the nested class. The s.o.p. for the
getTotalHeight always returns zero.
Does anyone have any suggestions? Do you need more information? Thanks in
advance - dan fox
