eforms: Studies in Radio Button Fields

| 0 comments

Some PDF previewer applications, notably PDF-XChange and
evince, do not handle radio buttons in the same way as do
AA/AR. A PDF viewer may not support PDF forms at all (such as
SumatraPDF), while others, such as TeXworks may supply
the appearances but not the functionality. PDF-XChange
supports PDF forms and Acrobat JavaScript, but handles radio
buttons differently.

In this article we discuss the various issues surrounding radio button fields, why they are a problem in certain PDF viewers, and how to correct the problem.

Continue by downloading studies-in-radios.pdf to your desktop and opening it in your favorite PDF viewer. Note: For the new Chrome Edge browser, the native PDF viewer supports form fields, and the radios on this article perform as designed.
