| | | Header/Footer Question? | Header/Footer Question? 2006-07-24 - By mcevikce
Back
I am trying to add header and footer to each page in my document but facing
two issues with it. I have followed the tutorial and extended
PdfPageEventHelper class.
1-) When I add just the footer, the footer is addedd to begining and the end
of the page.
2-) When I try to add the title I get stack overflow.
Here is the section of my code:
public void onEndPage(PdfWriter a_writer, Document a_document) {
try {
FooterCreator footerCreator = new FooterCreator(_helper);
a_document.add(footerCreator.createFooterTable(a_writer, a_document));
TitleCreator titleCreator = new TitleCreator(_helper);
a_document.add(titleCreator.createTitleTable(a_writer, a_document));
} catch (Exception e) {
throw new ExceptionConverter(e);
}
}
Title creator:
public PdfPTable createTitleTable(PdfWriter a_writer, Document a_document)
throws Exception {
float[] colWidths = new float[2];
colWidths[0] = (_helper.getBetterTableWidth() ) -
(VSTextUtility.getColumnWidth(_helper.getReportCreationTimeAndDate()));
colWidths[1] =
VSTextUtility.getColumnWidth(_helper.getReportCreationTimeAndDate()) ;
Rectangle page = a_document.getPageSize();
PdfPTable pdfPTable = new PdfPTable(colWidths);
pdfPTable.setTotalWidth(page.width() - a_document.leftMargin() -
a_document.rightMargin());
pdfPTable.setWidthPercentage(100);
addData(pdfPTable);
pdfPTable.writeSelectedRows(0, -1, a_document.leftMargin(), page.height()
- a_document.topMargin() + pdfPTable.getTotalHeight(),
a_writer.getDirectContent());
return pdfPTable;
}
FooterCreator:
public PdfPTable createFooterTable(PdfWriter a_writer, Document a_document)
throws Exception {
float[] colWidths = new float[1];
colWidths[0] = _helper.getBetterTableWidth();
Rectangle page = a_document.getPageSize();
PdfPTable pdfPTable = new PdfPTable(colWidths);
pdfPTable.setTotalWidth(page.width() - a_document.leftMargin() -
a_document.rightMargin());
pdfPTable.setWidthPercentage(100);
addData(pdfPTable);
pdfPTable.writeSelectedRows(0, -1, a_document.leftMargin(),
a_document.bottomMargin(),
a_writer.getDirectContent());
return pdfPTable;
}
Here is the exception:
