LXQT apps not respecting QT theme

Shark · 2015-05-13 07:43:42

Hello

So i decided to give a try to LXQT (i am a long time KDE user, tough). So far i am impressed but theming is pain in the ass. LXQT apps just dont respect my color scheme, KDE apps do. I have tried everything in this wiki https://wiki.archlinux.org/index.php/LX … _respected to no avail. Anybody experience same problems?

I don't use lxqt but maybe this can help you?

Hey,

thx for suggestion. I have tried but didn't work.

"Didn't work" means that this apps doesn't start or that starts but without any effect?
If it doesn't start - try prior (0.10) version. There is a PKGBUILD in AUR (qt5ct) or there: http://www.archlike.darmowefora.pl/inde … 200.0.html
I've noticed, that version 0.11 build well, but we cannot run it.

Application do start but the color scheme is not the one KDE apps have. I have installed 0.10 version but it doesn't have any effect. I just don't know how to change color scheme for LXQT appps.

Is there any special file or something to tweak color scheme for LXQT app? OVERRIDE variable doesn't work.

New insights. If i launch any LXQT app in KDE i get the right colorscheme. Then if i immediately go to LXQT session i get the wrong (default) color scheme.

Perhaps comparing environment variables gives a clue. In LXQT do:

env > env.lxqt

In KDE:

env > env.kde

then run:

diff -u env.kde env.lxqt

Also, the wiki article mentions KDE4, not sure if you use that or Plasma5.

The QT_PLUGIN_PATH looks similar to what's in the wiki, except kde5. So, add to /etc/environment

QT_PLUGIN_PATH=/usr/lib/qt/plugins:/lib/kde5/plugins/

There's some other variables you could try, like DESKTOP_SESSION.

I put both variable to /etc/environment to no avail. For DESKTOP_SESSION i have assigne value LXQt. Really weird.

Ouh, and what is also weird is that KDE systemsetting doesn't obey color scheme in LXQT environment also. Only apps like Konsole and Firefox (uses oxygen-gtk) but not also Thunderbird.

Do you have frameworkintegration installed?

Shark · 2015-05-14 13:16:22

Yes, i have the latest.

arojas · 2015-05-14 15:08:50

How are you setting your color scheme? I can't find any such setting in the LXQT configuration options

Through KDE5 system settings. But that doesn't work except for Dolphin and Firefox (oxygen-gtk) in LXQT.

Ah yes. That changes the KDE settings, not the Qt ones. So if you want Qt5 apps to pick up the change outside Plasma 5 you need to trick it into thinking that you're running a Plasma 5 session (export KDE_FULL_SESSION=true and KDE_SESSION_VERSION=5)

Shark · 2015-05-14 16:51:59

Doesn't work. I put those variables in /etc/profile, /etc/environment, .zshrc to no effect. I really don't know ... I am breaking my head for two days now, for colors sake

There isn't any

/lib/kde5

or any other kde5" directories in system with Plasma 5 (KF5) installed. All "plugins" are in /usr/lib/qt/plugins.
