Association with URLs in pdf files

piperfw · 04-03-2019, 10:16 AM

Since installing calibre I have found that when clicking on a URL in my pdf reader - Okular - instead of opening my web browser, as I would expect, Calibre's Edit book interface is opened with the error 'Unsupported format.'

I am wondering if anyone knows how to remove this association. Normal hyperlinks work correctly in the editor.

If you think this is an issue for the Okular forums, I will pursue it there instead.

Many thanks.

Additional information: Arch Linux 5.0.5, Okular 1.6.3, Calibre 3.40.1.

okular uses KDE which uses Qt and Qt inturn on linux uses xdg-open. So you need to figure out why xdg-open thinks the editor should be used to open URLs.

You can run xdg-open http://some/url

ina terminal to check what it does.

Thank you for the reply and apologies for taking so long to get back.

Running xdg-open http://some/url in the terminal opens a browser session, as expected. So does opening urls from other applications e.g. Sublime Text; the problem appears to be restricted to Okular. Is there anything else Okular might be using other than xdg-open? Or perhaps that urls embedded in a pdf lead to different behaviour (via xdg-open) than those found in plain text?

I dont know, I'm not an okular developer, you'd have to ask its developer for more info.
