Hi Paulo,
i've tried to implement your tip with the form field on one page and
kids in the next pages, but i have serious problems.
If you create the field on page 1 (and maybe the first kid) you
can't create a kid on page 2, as the field seems to be
written out, if a newPage() occurs.
Have a look at the code below.
If you create the second kid while the PdfWriter is on page 1,
it is added on the first page.
Do you have any idea how to add kids to fields on different pages?
Regards,
Peter
BTW: In Version 137 you didn't change anything about the fields, did you?
Here's the code for the naiv approach. In the resulting PDF only
the first kid appears.
public static void main(String[] args)
{
String strOutPDF = "D:/temp/with_fields_1.pdf";
System.out.println("Testing fields on different pages");
Document doc = new Document();
try
{
PdfFormField aFormField = null;
PdfFormField aSecondKid = null;
PdfFormField aFirstKid = null;
float fontSize = 12;
Color textColor = new GrayColor(0f);
BaseFont helv = BaseFont.createFont("Helvetica", "winansi",
false);
PdfWriter aWriter = PdfWriter.getInstance(doc,
new
FileOutputStream(strOutPDF));
doc.open();
PdfContentByte cb = aWriter.getDirectContent();
doc.add(new Paragraph("Page 1"));
aFormField = PdfFormField.createTextField(aWriter, false,
false, 100);
aFormField.setFieldName("ATextField");
aFirstKid = PdfFormField.createTextField(aWriter, false,
false, 100);
aFirstKid.setWidget(new Rectangle(171, 750, 342, 769),
PdfAnnotation.HIGHLIGHT_INVERT);
aFormField.addKid(aFirstKid);
aWriter.addAnnotation(aFormField);
doc.newPage();
doc.add(new Paragraph("Page 2"));
aSecondKid = PdfFormField.createTextField(aWriter, false,
false, 100);
aSecondKid.setWidget(new Rectangle(171, 450, 342, 469),
PdfAnnotation.HIGHLIGHT_INVERT);
aFormField.addKid(aSecondKid);
aWriter.addAnnotation(aSecondKid);
doc.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (DocumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("finished.");
}
