Users of a fillable form application have come back asking for the ability to have a square radio button.
Acrobat gives a dialog, Radio Button Properties, with Options > Button Style, which can be set to check, circle, cross, diamond, square, or star. I have been trying to understand how this is implemented using PDFBox, but have not had any luck. The sample PDF is at http://aapro.net/temp/squarebutton.pdf While "How to get square radio button" is what I'm required to know, "How to have figured that out using PDFBox" would also be of interest and appreciated. Thanks, Gary
