Hi,
Probably because they are indeed checkboxes. Seems there is missing
implementation of PdfRadioButton there is only this "// TODO: Dominiks
PdfRadioButton". To add radion button you need to add PdfButton and call
"SetFieldFlag(ePdfButton_Radio, true);". Radio buttons are grouped by using
same parent like this:
30 0 obj
<</FT/Btn
/P 1 0 R
/Kids[29 0 R 31 0 R 32 0 R ]
/T(Radio)
/Ff 49152
/V /Off
/DV /Off
>>
endobj
29 0 obj
<</Type/Annot/Subtype/Widget/F 4
/Rect[244.1 371.1 253.4 380]
/FT/Btn
/P 1 0 R
/Parent 30 0 R
/DR<</Font<</ZaDi 15 0 R>>>>
/DA(0 0 0 rg /ZaDi 0 Tf)
/MK<</CA(l)>>
/AP<<
/N<< /Off 77 0 R /1 78 0 R>>
>>
/AS /Off
>>
endobj
31 0 obj
<</Type/Annot/Subtype/Widget/F 4
/Rect[244.1 350.3 253.4 359.2]
/FT/Btn
/P 1 0 R
/Parent 30 0 R
/DR<</Font<</ZaDi 15 0 R>>>>
/DA(0 0 0 rg /ZaDi 0 Tf)
/MK<</CA(l)>>
/AP<<
/N<< /Off 79 0 R /2 80 0 R>>
>>
/AS /Off
>>
endobj
32 0 obj
<</Type/Annot/Subtype/Widget/F 4
/Rect[244.1 329.6 253.4 338.5]
/FT/Btn
/P 1 0 R
/Parent 30 0 R
/DR<</Font<</ZaDi 15 0 R>>>>
/DA(0 0 0 rg /ZaDi 0 Tf)
/MK<</CA(l)>>
/AP<<
/N<< /3 81 0 R /Off 82 0 R>>
>>
/AS /Off
>>
endobj
I have feeling that there is no direct support for creating nested pdf
fields which are required for radio grouping so probably one must setup
Kids and Parent manually.
