When using a Desktop Environment or Window Manager that doesn't allow for the settings of QT themes, you can set QT to use your GTK themes instead.

Using qt5ct

In some Manjaro editions, this is already done for you by default

Install qt5ct using your favorite package manager or the command:

user $ pamac install qt5ct COPY TO CLIPBOARD

Set environment variables in ~/.profile by adding or updating the following lines:


Run the application QT5 Configuration Manager from the menu or run the command qt5ct.

Logout and login again to make the change effective
