Thanks for the reply, but I think one of us of misunderstanding something..
checkbox.Option |= PdfFormField.FF_NO_TOGGLE_TO_OFF; looks to me like that
would set the checkboxes to NOT be uncheckable. This is the behaviour that I
want to remove, i.e. I want the checkboxes to be uncheckable, so that their
behaviour would be something like this :
given checkboxes A and B, both starting unchecked, click A->A is checked,
click B->A is unchecked and B is checked, click B->B is unchecked.
If it helps at all, here's a simplified example that should be runnable on
it's own (note that as it's iTextSharp, it would need to be changed a bit to
work in Java with plain old iText) :
Document document = new Document();
PdfWriter writer = PdfWriter.GetInstance(document, new
FileStream(@"C:\Users\Andre\Desktop\testpdf.pdf", FileMode.Create));
document.Open();
PdfContentByte canvas = writer.DirectContent;
Rectangle rect = new Rectangle(100, 100, 110, 110);
PdfFormField field;
PdfFormField radiogroup = PdfFormField.CreateRadioButton(writer,
false);
radiogroup.FieldName = "language";
RadioCheckField checkbox = new RadioCheckField(writer, rect,
"check1", "on_check1");
checkbox.Options |= PdfFormField.FF_NO_TOGGLE_TO_OFF;
field = checkbox.RadioField;
radiogroup.AddKid(field);
rect = new Rectangle(120, 100, 130, 110);
checkbox = new RadioCheckField(writer, rect, "check2",
"on_check2");
checkbox.Options |= PdfFormField.
field = checkbox.RadioField;
radiogroup.AddKid(field);
writer.AddAnnotation(radiogroup);
document.Close();
