I use Qt Assistant as a help viewer and I have an internal link to a PDF file that is embedded into the compiled archive format. When I click on that link, nothing happens. How can I link to a PDF file that is embedded, click on the link and have an external application opened? I use Qt Assistant 4.7.3.

Short of bundling a program like Okular into your application release and launching it as an external process there isn’t a native way of arriving at your solution. More options are discussed here as well, to sum it up it’s either externally or converting the PDF to a QPixmap.
