#71 Wrong theme when kwrite is opened with dolphin context menu

[Tuxo Holic]

When I lauch kwrite from the terminal or pick it from the start menu qt5ctl sets the theme correclty, but when I use the "open in kwrite" context menu entry in dolphin, kwrite opens without the qt5ctl adjustments. Same is true for konqueror. Do I have to fix something in the context menu entry? I use Debian 10/Buster with fluxbox, no plasma desktop is installed.

Try to add QT_QPA_PLATFORMTHEME="qt5ct" to /etc/environment

That's already set in Debian using /etc/X11/Xsession.d/99qt5ct. I see it using the env command.

Looks like dolphin does not use environment variables. Try to change Exec value of kwrite.desktop to something like this:
kwrite -platform qt5ct %F

Sorry that's not it. Some background task must be occasionally crashing without me noticing. If I login again the issue is gone for while until it reappears. I can't really say whether it is qt5ct or some other background task dolphin is using. All I can say is this: when it appears calling kwrite from the terminal is still running fine with qt5ct.

Might be related to how kde apps behave outside of kde, as dolphin and kate didn't honour my qt5ct theme in my Arch/Fluxbox system as well. I could solve dolphin issue by this workaround, but not kate. So eventually replaced dolphin with pcmanfm-qt and kate with qtextpad.
