[SOLVED] Qt env QT_QPA_PLATFORMTHEME= is not working for all Qt5 apps

Hi,

i am trying to implement below instructions: https://wiki.archlinux.org/title/Unifor … plications
especially i am using QT_QPA_PLATFORMTHEME="qt5ct"

but the main problem is that qt5ct settings are not working in all Qt5 apps. For example:
-- KeePassXC qt5ct settings are working
-- audacious everything is ok
-- XnViewMP are not working
-- wireshark - the same, settings are ignored

so i can say that only 50% Qt apps are using qt5ct. How can i force app to use QT_QPA_PLATFORMTHEME ? Its not big issue, but i would like to make my OS little more consistent. I am using xfce4

I also use xfce4 and qt5ct, and for me wireshark looks like this

But I have a ~/home/.profile file created and this content in it

export QT_QPA_PLATFORMTHEME="qt5ct"

i am using QT_QPA_PLATFORMTHEME="qt5ct"

How are you attempting to apply that, exactly?

export QT_QPA_PLATFORMTHEME="qt5ct" is inside ~/.bash_profile
and ~/.config/qt5ct exist

as I said: some apps are running correctly and some not. How can i debug why app is not respecting qt5ct?

QT_QPA_PLATFORMTHEME="qt5ct" inside ~/.bash_profile

That file is only read when you open a new bash shell.

Read https://wiki.archlinux.org/title/Environment_variables

Re: [SOLVED] Qt env QT_QPA_PLATFORMTHEME= is not working for all Qt5 apps

Ok, just noticed what is the issue

when i am running directly from shell:
wireshark or xnviewmp, then qt5ct is working

but when i am clicking via *.desktop file, then not.

Topic is solved. I will tweak some desktop files and it will work. Thanks

@Head_on_a_Stick - thanks for your suggestion
