[opensuse-kde] qdbus - is this still working in 5.19?
Hi I use this to display progress of my backup script during logout but it no longer displays anything (i used to use kdialog). I am having other issues with the logout process since installing tumbleweed:20200609 in that its completely changed how it works so it may be linked to that. regards Ian -- opensuse:tumbleweed:20200610 Qt: 5.15.0 KDE Frameworks: 5.70.0 - KDE Plasma: 5.19.0 - kwin 5.19.0 kmail2 5.14.1 (20.04.0) - akonadiserver 5.14.1 (20.04.0) - Kernel: 5.6.14-1-default - xf86-video-nouveau: 1.0.16 -- To unsubscribe, e-mail: opensuse-kde+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kde+owner@opensuse.org

qdbus is part of Qt4, which was dropped from Tumbleweed in Autumn last year, so you probably don't have it installed anymore. I don't know what you are doing exactly, but unless something else changed, you should be able to use qdbus-qt5 instead (or dbus-send, but that has a different syntax).

All i'm doing is backing up folders and I display which folder is about to be backed up. I'll update my script to qdbus-qt5 and see how that goes.
Thanks for the info.

Ok, but how exactly are you displaying the folder? qdbus(-qt5) is just a tool to send messages via D-BUS to some application, it doesn't really do anything by itself.

Ok, but how exactly are you displaying the folder? Its just text i'm sending to the screen. I used to use kdialog directly but when that stopped working, i was given qdbus as a replacement way of displaying text on the screen after logout so i can see progress. I can't find the original email where i was told about how to do it. This is how i was doing it with "qdbus"
dbusRef=`kdialog --progressbar "Starting Back up procedure" 4` sleep 1 qdbus $dbusRef Set "Starting Back up procedure" value 1 rsync ...... qdbus $dbusRef Set "" value 1 qdbus $dbusRef setLabelText "1.4. Backing up /home/me/Documents"

So you are in fact using kdialog, and try to update its progressbar and text later on via D-BUS. ;-) This is wrong though: $ qdbus $dbusRef Set "Starting Back up procedure" value 1 Error: org.freedesktop.DBus.Error.UnknownInterface Interface Starting Back up procedure was not found in object /ProgressDialog It should probably be just: $ qdbus $dbusRef value 1 (or whatever value you want to set) The setLabelText line should be fine though.

The setLabelText line should be fine though.

Yes, i've now updated to qdbus-qt5 and it now works as it used to. The actual problem was the wrong command though. In principle it works the same with Qt4's qdbus, but as I said that's not available anymore in Tumbleweed.
Btw, I just tested with an old KDE4 version of kdialog (15.04.3, self- compiled) as well, and it gave the same error.
thanks again for replying and getting it working again. You're welcome.
Hint: it's always a good idea trying to interactively run the commands in konsole in such a case, to see what's going wrong... ;-) Kind Regards, Wolfgang -- To unsubscribe, e-mail: opensuse-kde+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kde+owner@opensuse.org

Although, it might be that qdbus (and maybe Qt4 as a whole) broke or got uninstalled after the whole distribution was rebuilt with gcc 10. Would explain why it stopped working *now*, I suppose... That one line was still wrong though, and certainly didn't work before either. Even if you might not have noticed it. ;-) Kind Regards, Wolfgang -- To unsubscribe, e-mail: opensuse-kde+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kde+owner@opensuse.org

Would explain why it stopped working *now*, I suppose... Just discovered that it still doesn't display on logout although the backup works fine. It displays okay in konsole where i was testing it. I'm also getting a few coredumps for each logout - kdialog, drkonqi, plasmashell, qdbus-qt5, i don't get them when I test in konsole. I've got a problem with logout since 5.19 and it may be part of the problem of not displaying. https://bugs.kde.org/show_bug.cgi?id=422834

I didn't notice, the backup worked and the display seemed okay. :)

Hm, I don't think I have that problem here. I'm using Leap though (that may explain a difference), but I might just not have noticed it (on Leap, coredumps are disabled by default, and I didn't enable them).

Yeah, if that was the only wrong line, it would just not set the initial value to 1, and the rest may have worked fine. Kind Regards, Wolfgang -- To unsubscribe, e-mail: opensuse-kde+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kde+owner@opensuse.org

There is a "bug" in Oxygen 5.19.0 that causes applications to crash on exit. Breeze was affected as well (in 5.19 beta), but there it was fixed in time for the 5.19.0 release. https://bugs.kde.org/show_bug.cgi?id=421434 Although, that probably shouldn't cause qdbus-qt5 to crash at least... And I didn't see the crash with kdialog now either. Maybe it would help if you provided a backtrace.

i've never been presented with the option to generate a backtrace. No, but you say they are listed, by coredumpctl I suppose. So you should be able to extract via coredumpctl as well.
