Hi Tilman,
Whatever code I send yesterday not worked with change
|widget.setAppearanceState(i
==on
?options.get(i):"Off");|
But I refer the code https://stackoverflow.com/ques
tions/41631119/radiobutton-display-problems-with-pdfbox and tried the
|widget.setAppearanceState(i
==on
?options.get(i):"Off");| as I attached in previous mail.
and thats work fine. But issue coming when another radio button is clicked.
Please suggest me the better approach for radiobutton with selected value.
Thanks,
Bharat
