[SOLVED] application style only affects current windows in plasma

Furlinastis · 05-26-2020, 11:06 PM

I set application style to breeze. But then when I open another application, even like Dolphin or Kinfocenter, it uses some dark application style. I work around this by setting --style=Breeze in the .desktop icon in the menu, but I want a global solution and not all apps have the --style setting.

Also, if I unset environmental value QT_STYLE_OVERRIDE and export QT_QPA_PLATFORMTHEME=qt5ct it works fine but only if I open the applications with command line.

How would I set this for "global" use?

Do you have qt5-settings installed and what version of KDE &c?

What package does qt5-settings belong to? It's not installed on my system.

KDE plasma 5.18.5 kde framework 5.70.0 qt 5.14.2 kernel 5.6.14

Is it in the repo, otherwise it changed to just (Qt5 Configuration Utility) qt5ct?

I do have qt5ct installed.

When I open qt5ct (from menu) I get a message "the application is not configured correctly" with 'information' and 'hide' buttons. When I click 'information' I get this message:

Code:

Please remove the QT_STYLE_OVERRIDE environment variable (current value: gtk2).

The QT_QPA_PLATFORMTHEME environment variable is not set correctly (current value: KDE, required value: qt5ct).

Ok, I just did export QT_QPA_PLATFORMTHEME=qt5ct, and it seems to work, from commandline, but it says it's not configured correctly and info says:

Code:

The QT_QPA_PLATFORMTHEME environment variable is not set correctly (current value: KDE, required value: qt5ct).

Doesn't KDE have an environmental values settings somewhere?

Ok, I altered the two variables in /etc/environment and now the problem has been solved.
