Is there a way to see if the PDF extension is currently active in TChromium? I need to know when the user is browsing a PDF file in the PDF extension.

It there a direct way to do it or should I sniff the current URL address for a .pdf file extension?

Hi,

You can check the HTTP response headers to see if you received a Content-Type : application/pdf header or you can visit the DOM and search for an EMBED element with a type="application/pdf" attribute.
