How to prevent Qt Applications from using GTK+ theme

Whenever I want to use custom QML components in my apps it makes them use GTK+ theme. How can I prevent this? Why am I asking here? Because I believe it has something to do with files like: `~/.config/qt.conf` or whatever. And I have to do something like: [Qt] GTK-theme: false Or something in this "style", but I don't know what/how exactly should I do it. Can you help me with this? **I'm using ArchLinux and GNOME as DE if it can help.**
