Thanks Monte.
I should have been more explicit in that I’d tried that technique to handle the
linkClicked message - none of the links in my test PDFs (that work in Preview
and Adobe) fire it.
Assuming I’ve not missed any widget properties, it looks like there’s a problem
with the underlying PDFium library not finding ‘clickables’ in the PDF
documents - or the LC wrapping has a bug...
If navigation is under script control the documentation suggests that every
‘clickable’ that works in any PDF viewer would need to be extracted into either
the documentBookmarks or documentNamedDestinations arrays to be accessible for
scripting - and both are empty for my ‘link-rich’ test PDFs.
Maybe the premium subscription for this widget means that it’s not been
accessible for beta-testing by the user community, as I see nothing in the QA
centre.
Best,
Keith
