Ah.
Okay, then just drop the extra parameter in the createCheck() call (or change
it to false, same results). The kids were inheriting the parent's behavior.
And don't set the kid's option either.
Final Point: If you're using some Off Brand PDF viewer, they may not have
implemented the "toggle to off" behavior in the first place (or they have a
bug).

Subject: Re: [iText-questions] iTextSharp RadioGroup noToggleToOff
notworking.
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();

Took me a couple readings of the code to figure this one out
myself.
CreateRadioButton creates the visual element for a radio button
field, not the parent field under which the kids reside. The "no toggle off"
behavior should be in the individual child fields, not the parent.
The parent field is working, so that's clearly not a big deal.
And to fix your button creation code, you need to add:
checkBox.options |= PdfFormField.FF_NO_TOGGLE_TO_OFF;
No that isn't one of the listed options in BaseField's JavaDoc.
The full list of valid options are all the PdfFormField.FF_* contstants, some
of which are duplicated in BaseField without the leading FF_.

Subject: [iText-questions] iTextSharp RadioGroup
noToggleToOff not working.
Here are the bits of code in question :
[code]
PdfFormField group1 =
PdfFormField.CreateRadioButton(writer, false);
group1.FieldName = "group1";
group1.AddKid(CreateCheckBox(over,
"check1", 8.5f, 363, 459.8f + GIFLOffset_1, 0.3f));
group1.AddKid(CreateCheckBox(over,
"check2", 8.5f, 471, 459.8f + GIFLOffset_1, 0.3f));
writer.AddAnnotation(group1);[/code]
and the CreateCheckBox method :
[code]
private static PdfFormField
CreateCheckBox(PdfContentByte layer, String name, float size, float llx, float
lly, float thickness)
{
PdfFormField field;
RadioCheckField checkbox;
Rectangle rect = new Rectangle(llx, lly,
llx + size, lly + size);
checkbox = new
RadioCheckField(layer.PdfWriter, rect, name, "on_" + name);
checkbox.CheckType =
RadioCheckField.TYPE_CHECK;
checkbox.BackgroundColor = BaseColor.WHITE;
checkbox.BorderColor = BaseColor.BLACK;
checkbox.BorderStyle =
PdfBorderDictionary.STYLE_SOLID;
checkbox.BorderWidth = 0.4f;
checkbox.FieldName = name;
field = checkbox.RadioField;
layer.Rectangle(rect);
layer.SetLineWidth(0.4f);
layer.Stroke();
return field;
}[/code]
This code is part of a larger program that generates a
customized document. The checkboxes are created fine and show up properly, and
I can check one or the other (but not both) as expected, however they cannot be
unchecked at all.
I was under the impression that the false value passed
into the CreateRadioButton method should make it so that you can uncheck a box
so that neither will be checked, but even changing that to true had no effect
on behaviour (that behaviour being that once one of the checkboxes is checked,
one will always be checked unless a reset button elsewhere on the form is
clicked).
Any help getting the checkboxes to be uncheckable would
be greatly appreciated.
