Adding a Checkbox to a PDF Document using iText
13,335
Here is how you can do it using Windings font:
BaseFont base = BaseFont.createFont("C:\\Winodws\\fonts\\wingding_0.ttf", BaseFont.IDENTITY_H, false);
Font font = new Font(base, 16f, Font.BOLD);
char checked='\u00FE';
char unchecked='\u00A8';
Document document = new Document();
PdfWriter.getInstance(document, new FileOutputStream(filename));
document.open();
// Here is how to add a checked checkbox
document.add(new Paragraph(String.valueOf(checked),font));
Here is an unchecked checkbox
document.add(new Paragraph(String.valueOf(unchecked),font));
document.close();
If you want to add any extra character, just reference the Windings character set: http://www.alanwood.net/demos/wingdings.html

I need to create a PDF Document using Java's iText libraries. I need to include as well some checkboxes, which are on/off depending on the value of some class variables. I've found some examples about interactive forms but I don't need this level of complexity: just some checkboxes which are added to a basic document like this:
public class SamplePDF { public static final String RESULT = "hello.pdf"; public static void main(String[] args) throws DocumentException, IOException { new SamplePDF().createPdf(RESULT); } public void createPdf(String filename) throws DocumentException, IOException { Document document = new Document(); PdfWriter.getInstance(document, new FileOutputStream(filename)); document.open(); document.add(new Paragraph("Document Heading")); // // Add Checkboxes here // document.close(); } }
Any help ?
