RE: [iText-questions] SubTotals, count, ....
You are complicating too much, you don't need templates. Do as follows:
- read all the rows to a PdfPTable. You now have the total number of rows.
- place the table at a precise position 10 rows per page using
PdfPTable.writeSelectedRows().
- draw the text for the page using the total number of rows.

RE: [iText-questions] SubTotals, count, ....
UFFA, READING TWICE OR THREE TIMES I REALIZED I NEED AN COURSE OF "LEARN IN
2 DAYS HOW TO MAKE QUESTIONS EASY TO UNDERSTAND" ...
My PDF has always a table with 10 rows (it could be that it's filled in the
first 2 rows, and the rest are empty). So, for instance, if my PDF consists
of 1 page and tha table only has 4 rows with data, the total rows printed it
would be 4; if it consists of 2 pages, that's means that in the first page
the table has all the 10 rows with data, and in the second page the table
could have just data in one row, the first one, so altogether I have 11 rows
and in each page i have to print "Total number of rows:11" (Don't ask me why
I have to do such a strange thing). So ...
1. The first possible solution 'fitsPage'
> If your data is in a table, working with fitsPage could be

I guess it doesn't "fit" my problem as I will always have page with a fixed
nmber of rows
2. I thought in using the way is explained how to add the total number of
pages with the GenericTagEvent
So
i.- I increase this counter in onGenericTag(...) method
ii.- as i have to show in each page the total of rows (similar to total
number of pages) for the whole PDF I'll have to use the onCloseDocument()
method, no?
Following the examples you give I'll have sth like
// we override the onEndPage method
public void onEndPage(PdfWriter writer, Document document)
{
int pageN = writer.getPageNumber();
String text = "Page Number": " + pageN + "/ ";
float len = bf.getWidthPoint(text, 7);
// Rectangle for Total number of lines
cb.rectangle(...);
cb.setColorFill(...); // I set to White
cb.closePathFillStroke();
cb.setColorFill(); // I set it to Black
// Rectangle for Number of Pages
cb.rectangle(...); // Different position of course ;-)
cb.setColorFill(..); // Again to White
cb.closePathFillStroke();
cb.setColorFill(...); // Again to Black
cb.beginText();
cb.setFontAndSize(bf, 7);
cb.setTextMatrix(...); // In Position A
cb.showText(text);
cb.endText();
cb.addTemplate(...);
cb.beginText();
cb.setFontAndSize(bf, 7);
cb.setTextMatrix(...); // In Position B
cb.endText();
}
and I thought in a onCloseDocument like ...
public void onCloseDocument(PdfWriter writer, Document document)
{
// Total of pages
template.beginText();
template.setFontAndSize(bf, 7);
template.showText(String.valueOf(writer.getPageNumber() - 1));
template.endText();
// Total of rows
template.beginText();
template.setFontAndSize(bf, 7);
template.showText(String.valueOf(totalLines)); // The counter
template.endText();
}
it would work, but due to the the setMatrix at the end of onEndPage each
showText i use in onCloseDocument will be related to the position indicated
in the lastMatrix, won't it? I mean, i'll have in the same position the
total number of pages and the total number of rows with data. I tried with a
cb.beginText();
cb.setFontAndSize(bf, 7);
cb.setTextMatrix(...); // In Position C
cb.endText();
in the onCloseDocument() between the block for total of pages and total of
rows but no success. So, is there a way to write two texts in
onCloseDocument in two different positions?
Uff, I hope this time managed to make a more clear question ;-)

Sergio

You would have to change iText internally. No, this is not an option. To meet your needs a 'GenericTagEvent' is added. You could pass a String (for instance "1;1.500") as a generic tag. This String can be parsed in the EventHandler: add 1.500 to the counter of column 1. See example 9 of Chapter 2 for an example on generic tags. So now you have a 'luxoury problem', instead of no solution, you can chose between two solutions: 1. you put all your data in a table and keep track of all sums. As soon as the table doesn't fit the page, you delete the last row of data (and change the sums accordingly) and you add a row with the sums to the table before you add it to the document. You start with a new table on the next page. 2. you let the Event class handle all calculations. You pass all values with a generic tag and onPageEnd you put the sums at absolute positions on every page. kind regards, Bruno ___ iText-questions mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/itext-questions

Quoting Sergio Lopez Rodriguez <[EMAIL PROTECTED]>: > I need to add subtotals, count and other kind of group functions to a > report. I think i must use Events, mustn't I? Why? What do you want to achieve? Also keep in mind that iText is not like EXCEL. How do you expect to pass the different values that need to be calculated to the Event class? Isn't it simpler to keep a counter in your loop that adds the different items and add the results when the loop is finished? > To create the PDF I'm using servlets that extends from a specific Servlet, > let's say I have > > CarServlet extends OtherServlet > > OtherServlet it's predefinined so I can't change its definition.

Why would you let a Servlet extend PdfPageHelper? I don't understand the way you think. No Servlet can ever extend PdfPageEventHelper (why should it have to?). Normally you create a seperate class MyHelper that extends PdfPageHelper and in that class you define the behaviour of your events. You use an instance of this class in the setEvent method. It's as simple as that... ___ iText-questions mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/itext-questions
