qt6ct - Qt6 Configuration Tool
This program allows users to configure Qt6 settings (theme, font, icons, etc.) under DE/WM without Qt integration.
Official home page: https://github.com/trialuser02/qt6ct
Requirements:
- GNU Linux or FreeBSD
- qtbase >= 6.0.0
- qtsvg >= 6.0.0 (Runtime dependency for the SVG icon support)
- qttools >= 6.0.0 (For build only)

-
Arch package https://archlinux.org/packages/?q=qt6ct

Source Code (qmake) qmake PREFIX=
make sudo make install -
Source Code (cmake) cmake -DCMAKE_INSTALL_PREFIX=
make sudo make install
Add line 'export QT_QPA_PLATFORMTHEME=qt6ct' to ~/.profile and re-login. Alternatively, create the file /etc/X11/Xsession.d/100-qt6ct with the following line:
export QT_QPA_PLATFORMTHEME=qt6ct
(or qt5ct for compatibility with Qt5 Configuration Tool)

Extra build options (for advanced users only):
