PDF Form fields with relative position.

PDF Form fields with relative position.

Hi to all.

I'm trying to create form field in a PDF using iText. But I don't know the
absolute position of this fields on the final document nor in the final
page. I find a way to add Text Fields to a document relatively to the text
added to it, but now I need to do the same with CheckBox, Radio Button, List
and Combos.

To add Text Fields relatively to a text, I create a Chunk and asociate
text field to the Chunk's annotation, following this : Chunk.setAnnotation
(annotation). This works, but when I tried the same way with check boxes,
the controls do not appear on the PDF.

Here is the source code than I try:

nuevo_elemento = new Chunk ("");
// Chunk to set the relative position of the Check Box.

PdfFormField check1 = PdfFormField.createCheckBox(escritor);

Rectangle rect = new Rectangle(0, 0, 20, 20);
// Position to set the widget

check1.setFieldName("tarjetaCredito");

check1.setValueAsName("Off");

check1.setWidget(rect, PdfAnnotation.HIGHLIGHT_INVERT);

check1.setAppearanceState("Off");

check1.setAppearance(PdfAnnotation.APPEARANCE_NORMAL, "Off",
tpOff2);

check1.setAppearance(PdfAnnotation.APPEARANCE_NORMAL, "On",
tpOn2);

nuevo_elemento.setAnnotation(check1);
// Associate Check Box (check1) with his content Chunk (nuevo_elemento)

doc.add (nuevo_elemento);
