How do you create a Radio Button Group with PDFBox 2.0?
Hi
I want to create a Radio Button group using PDFBox 2.0, I am able to create 3 Radio Buttons, but I can't figure out how to group them (PDFBox 1.8, used PDRadioCollection<https://pdfbox.apache.org/docs/1.8.10/javadocs/org/apache/pdfbox/pdmodel/interactive/form/PDRadioCollection.html>, but 2.0 doesn't.).
How do you create a Radio Button Group with PDFBox 2.0?
Here is my current code:
PDDocument document = new PDDocument();
PDPage page = new PDPage(PDRectangle.A4);
document.addPage(page);
PDAcroForm acroForm = new PDAcroForm(document);
acroForm.setNeedAppearances(true);
document.getDocumentCatalog().setAcroForm(acroForm);
PDResources res = new PDResources();
COSName fontName = res.add(PDTrueTypeFont.load(document, new FileInputStream("C:/Windows/Fonts/arial.ttf"), StandardEncoding.INSTANCE));
acroForm.setDefaultResources(res);
acroForm.setDefaultAppearance('/' + fontName.getName() + " 10 Tf 0 g");
PDPageContentStream contents = new PDPageContentStream(document, page);
List<String> options = Arrays.asList("a", "b", "c");
for (int i = 0; i < options.size(); i++) {
PDRadioButton button = new PDRadioButton(acroForm);
button.setPartialName("RadioButton" + options.get(i));
PDAppearanceCharacteristicsDictionary fieldAppearance = new PDAppearanceCharacteristicsDictionary(new COSDictionary());
fieldAppearance.setBorderColour(new PDColor(new float[]{0, 0, 0}, PDDeviceRGB.INSTANCE));
PDAnnotationWidget widget = button.getWidgets().get(0);
widget.setRectangle(new PDRectangle(30, 800 - i * (21), 16, 16));
widget.setAppearanceCharacteristics(fieldAppearance);
acroForm.getFields().add(button);
page.getAnnotations().add(widget);
}
contents.close();
document.save(new FileOutputStream("RadioButtonTest.pdf"));
document.close();
Cheers
Adam

Thanks, this works nicely. You don't need the font and the appearance
streams contents (but it must exist) anymore, so the shorter code could
look like this. I've also changed the background. I'll keep that code
for the next person who asks :-)
public static void main(String[] args) throws IOException
{
String fileName = "C:\\Users\\Tilman
Hausherr\\Documents\\Java\\PDFBoxPageImageExtraction/RadioButtonsAdam.pdf";
String selectedValue = "a";
String name = "Radio";
PDDocument document = new PDDocument();
PDPage page = new PDPage(PDRectangle.A4);
document.addPage(page);
PDAcroForm acroForm = new PDAcroForm(document);
acroForm.setNeedAppearances(true);
document.getDocumentCatalog().setAcroForm(acroForm);
PDPageContentStream contents = new
PDPageContentStream(document, page);
List<String> options = Arrays.asList("a", "b", "c");
PDRadioButton radioButton = new PDRadioButton(acroForm);
radioButton.setPartialName("RadioButton");
List<PDAnnotationWidget> widgets = new ArrayList<>();
for (int i = 0; i < options.size(); i++)
{
PDRadioButton subRadioButton = new PDRadioButton(acroForm);
subRadioButton.setPartialName(name);
PDAnnotationWidget widget = subRadioButton.getWidgets().get(0);
PDAppearanceCharacteristicsDictionary fieldAppearance = new
PDAppearanceCharacteristicsDictionary(new COSDictionary());
fieldAppearance.setBorderColour(new PDColor(new float[]{0,
0, 0}, PDDeviceRGB.INSTANCE));
fieldAppearance.setBackground(new PDColor(new float[]{1, 1,
1}, PDDeviceRGB.INSTANCE));
widget.setRectangle(new PDRectangle(30, 800 - i * (21), 16,
16));
widget.setAppearanceCharacteristics(fieldAppearance);
widget.setPage(page);
widget.getCOSObject().setItem(COSName.PARENT, radioButton);
widget.setAnnotationFlags(4);
widget.setAppearanceState(options.get(i).equals(selectedValue) ?
selectedValue : "Off");
widget.setHighlightingMode("N");
PDAppearanceDictionary ap = new PDAppearanceDictionary();
COSDictionary aeDict = new COSDictionary();
COSStream off = new COSStream();
off.setItem(COSName.BBOX, new PDRectangle(0, 0, 16, 16));
aeDict.setItem("Off", off);
COSStream on = new COSStream();
on.setItem(COSName.BBOX, new PDRectangle(0, 0, 16, 16));
aeDict.setItem(options.get(i), on);
PDAppearanceEntry ae = new PDAppearanceEntry(aeDict);
ap.setNormalAppearance(ae);
widget.setAppearance(ap);
widgets.add(widget);
page.getAnnotations().add(widget);
}
radioButton.setWidgets(widgets);
System.out.println(radioButton.getOnValues());
radioButton.setValue(selectedValue);
acroForm.getFields().add(radioButton);
System.out.println(radioButton.getValue());

we will start working on that after 2.0 is out as we will also need that for PDF 2.0 support which mandates that the appearance stream is generated.

HI Tilman
Thanks for your help, regarding "pdAcroForm.setNeedAppearances(true);", will pdfbox have a default appearance in the future, so need appearances will not be needed?
I have a working solution to set default values and have acrobat render them. It was pure fluke that I got this result, but wanted to post it so other will know and to close out the solution.

Yes, it is a bit of a hack. Good applications should create their own appearance streams. In PDF 2.0 it will be mandatory.

RE: How do you create a Radio Button Group with PDFBox 2.0?
Posted by Adam Steen <ad...@rmt.com.au>.
I am now able to create a radio button group with "pdAcroForm.setNeedAppearances(true);", acrobat rendering things nicely for me.
I am also able to create a group of checkboxes with default values also with "pdAcroForm.setNeedAppearances(true);", again acrobat rendering things nicely for me.
My last hurdle is to create a radio button group with "pdAcroForm.setNeedAppearances(true);" and have a default value (or value) be displayed.
Using your code provided earlier Tilman, I was able to set a value or a default value, but acrobat just does not want to render it.
Is " pdAcroForm.setNeedAppearances(true);" a hack? Should I be rendering everything myself?
Adam

Indeed. I've been there too and looked through the code.

It seems without building an appearance I am unable to set a default value?
Does anyone have any ideas?

Hi
I did manage to get a Radio Group functioning, I have posted the code to my question on stack overflow -> http://stackoverflow.com/a/34895158/415681
The next problem will be getting a default value set.

Here's the code I did yesterday:
http://justpaste.it/CreateRadioButtons
The problem is that Adobe does things on its own even if the appearance streams are set. This seems to be related to the appearance characteristics (/MK). I haven't been able to teach it to "do nothing", or "do it all" when I do nothing (having empty streams).

Here's the code I did yesterday:
http://justpaste.it/CreateRadioButtons
The problem is that Adobe does things on its own even if the appearance streams are set. This seems to be related to the appearance characteristics (/MK). I haven't been able to teach it to "do nothing", or "do it all" when I do nothing (having empty streams).
