File dialog in KDE Plasma 5 on Linux

firus · 08-02-2017, 12:50 AM

Hello,

I'm using Linux Mint 18.2 KDE. I installed Calibre 3.5 using command from Calibre website.

Calibre is using its own file dialog for add books, choose working directory etc. And I cannot make it to use system (Qt5) file dialogs. I also tried GTK based desktop environment, but nothing works (only installing Calibre from repos, but it's old and outdated, some 2.x version)

It's not a big deal, but it would be nice to have Calibre fully integrated.

Does anybody know a solution to this?

Thanks.

There isn't one. Linux has no stable API to access native file dialogs, unlike OS X and Windows. The only way to make it work is to use a distro calibre package or build calibre from source.

Thanks for quick answer! You saved me a lot of time googling.

Actually, I added some code to use native file dialogs via zenity or kdialog, when available for the next release.

Awsome, thank you! I tested it with todays update. Zenity works just fine (in ubuntu 16.04 and mint cinnamon 18.2), but kdialog doesnt. I tested it on Mint kde 18.2 (which has both zenity and kdialog) and live Kubuntu 17.04(only kdialog installed). I'm going to try and eventually file a bug on launchpad.

However, I started to use Calibre only a while ago, when i got my Kobo reader. And it's a great piece of software! I'm going to donate and maybe find out another way to contribute.

Thank you.

kdialog works on my system. What error do you get? It may be that you need a newer version of kdialog.

This is the output from terminal:

Traceback (most recent call last):

ValueError: KDE file dialog aborted with return code: 254 and stderr: kdialog: Neznáma možnosť 'desktopfile'.

Dont know if desktopfile is somthing in your python code, or an option of higher version of kdialog. I'm on KDE 5.8.7, kdialog 1.0. Same error occurs with Kubuntu 17.04 which has KDE 5.9.4 but the same version of kdialog.

"Neznáma možnosť" in output means "Unknown option".

This is what the kdialog in my system outputs:

kdialog --help | grep desktopfile
--desktopfile <file name> The base file name of the desktop entry for

This is with kdialog version 17.04.3
