At first, I did not realize that the writer was available through the cb
member.
Now I have the solution I was looking for using a PdfAnnotation. Thanks for
the help!
// This is the straightforward, original way that iText
// adds hyperlinks to text. The problem is that Acrobat Reader
// shows the full ugly URL in an unsuppressable tooltip.
PdfAction action = new PdfAction(url.toString());
cb.setAction(action, (float)leftX, (float)leftY,
(float)(leftX+width), (float)(leftY+height));
// This JavaScript action acts the same as the code above,
// but does not show any tooltip in Acrobat Reader.
final PdfWriter writer = cb.getPdfWriter();
final PdfAction action = PdfAction.javaScript(
"if(app.viewerVersion<7) {" +
" this.openURL(\""+ url.toString() + "\", true);" +
"} else {" +
" app.launchURL(\""+ url.toString() + "\", true);" +
"}",
writer );
final PdfAnnotation link = new PdfAnnotation(
writer,
(float)leftX, (float)leftY, (float)(leftX+width),
(float)(leftY+height),
action );
link.setHighlighting( PdfAnnotation.HIGHLIGHT_NONE );
writer.addAnnotation( link );
