I’m using Archcraft with bspwm right now. It uses qt applications as default mostly. I don’t like the default qt file picker dialog it uses. And couldn’t find any good guideline to change the picker. So I’m going to write down a workaround I got from @ahmubashshir.

We need some dependencies :

  • qt5ct
  • kvantum-qt5
  • xdg-desktop-portal-gtk

Create a config file under ~/qt5ct/qt5ct.conf with the following content :


Now set the following environment variable at startup.


As I’m using bspwm I’ve put that on bspwmrc. You can put that on ~/.xprofile or something like that if you’re using X11.

That’s all you need to do. If you don’t know anything about environment variable, I suggest you to duck about that.
