bq. We do not support showing pdf files inside Assistant, we basically dump them out of the compressed help file and use the corresponding desktop application to show it.

Ah, yes, that's what I thought. I was a bit confused by posts like this, though:

Looks like you aren't. If it has worked for you but it doesn't anymore you should file a bug-report.[/quote]

I've found that as a workaround, PDFs may be packaged with a non-standard filename suffix - I've used ".pdf_". Qt Assistant will then fail to understand that the files have PDF format and will thus not assume they may be viewed internally. The desktop support routine that is called as a consequence, to open the files with an external application, will on the other hand still recognise them (based on content, I suppose) - at least on my setup.
