public class FormRadioGroup

extends FormElement

This class represents the Radio Group field of PDF Forms.

Radio buttons, like check boxes, allow a user to select one or more items from a list. The main difference between radio buttons and check boxes, as provided by Adobe Acrobat, is the appearance and the fact that at least one annotation for each Radio Button must be set.

Here is an example:

 
 FileInputStream fis = new FileInputStream("C:\\JustFormsPDF\\examples\\AddressForm32A2.pdf"); 
 PDF pdf = new PDF(new PDFReader(fis));
 Form form = pdf.getForm();
                   
 FormRadioGroup ethnic = (FormRadioGroup) form.getElement("ethnic");
 ethnic.setValue("ETH02");

 //ethnic.setValueByIndex(2);
