I can able to create the fillable form fields using PDF Box in the desired format but when I try to run the file through NVDA or JAWS screen reader.
It's not reading the newly created form fields.
Is there any specific property values available to make fields to be reading out through screen reader.
I had included my source code below for the reference.
for (PDPage page : pages) {
int pageIndex = pages.indexOf(page);
PageStructElementDetail _pgstrele = _ElementsByPageUtility._ElementsByPage.get(pageIndex);
int pageHeight = ((Float) _pgstrele.getPageHeight()).intValue();
// Add a new AcroForm and add that to the document
PDAcroForm acroForm = new PDAcroForm(_pdfDocumentObj);
_pdfDocumentObj.getDocumentCatalog().setAcroForm(acroForm);
Set<String> processedCheckBoxSet = new HashSet<String>();
for (StructElementDetail element : _pgstrele.getStructElementDetails()) {
try {
if ((element.getElementType().startsWith("TB"))) {
System.out.println("Inside TB");
if (element.getIsFillableFormField()) {
List<Integer> _int_bbox_list = convertBBOXtoIntegerList(element.getBBOX());
Integer xVal = _int_bbox_list.get(0);
Integer yVal = pageHeight - _int_bbox_list.get(1);
Integer width = _int_bbox_list.get(2) - _int_bbox_list.get(0);
Integer height = _int_bbox_list.get(1) - _int_bbox_list.get(3);
System.out.println(" _int_bbox_list Values [ " + _int_bbox_list.toString() + " ] ");
System.out.println("Print axis Values [ xVal : " + xVal + "] [ yVal : " + yVal
+ " ] [ width : " + width + " ] [ height : " + height + " ] ");
