I have used and adapted the onEndPAge() example and everything works
nicely. I have tried adding a a big fat table as my header and it doesn't
display right, it seems like it is reacting to my margins that I have set
for the ColumnText but when I change them it exhibits the same behavior.
Here is the code:
App Code (Clip)
---------------------------------------
PdfPTable head = new PdfPTable (2);
try {
head.addCell(Image.getInstance("images/DVLogo.jpg"));
head.addCell(company);
head.addCell(custTextArea.getText());
head.addCell("Date: "+ dateField.getText()+ " Invoice # "+ num);
PdfPTable itemHeader = new PdfPTable (7);
// int headerwidths[] = { 10, 20, 40, 10, 5, 5, 10 };
itemHeader.setWidthPercentage(100);
//itemHeader.setWidths(headerwidths);
itemHeader.addCell("Qty");
itemHeader.addCell("Code");
itemHeader.addCell("Description");
itemHeader.addCell("Unit$");
itemHeader.addCell("Tax1");
itemHeader.addCell("Tax2");
itemHeader.addCell("Ext. Total$");
PdfPCell cell = new PdfPCell(itemHeader);
cell.setColspan(1);
head.addCell(cell);
inv.setHeader(head);
