Make QT5 and QT6 apps use your GTK theme

This is a drop-in solution, unlike some others that use a GUI and you have to manually adjust colors.

First install qt5-gtk2-platformtheme from the repo. For QT6 you will need to download and install the package qt6gtk2 that is appropriate for your platform, you can find them here:
https://software.opensuse.org//download … ge=qt6gtk2

Next, create (or modify) .xsessionrc in your users home folder, and add these lines:
export QT_QPA_PLATFORMTHEME=gtk2 then save and close.

That's it. You may need to logout or reboot for changes to take effect.
