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)
Installation:
- Arch package
https://archlinux.org/packages/?q=qt6ct
- Source Code (qmake)
qmake PREFIX=<your installation path>
make
sudo make install
- Source Code (cmake)
cmake -DCMAKE_INSTALL_PREFIX=<your installation path>
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)
Now restart X11 server to take the changes effect.
Extra build options (for advanced users only):
qmake DISABLE_WIDGETS=1 - compiles platform plugin without QtWidgets (useful for QML applications only)
qmake PLUGINDIR=<custom path> - changes the default installation path of the plugins (libqt6ct.so and libqt6ct-style.so)
Wayland:
If you are running Qt application under Wayland, you should export the following variables:
export QT_QPA_PLATFORM=wayland
export QT_QPA_PLATFORMTHEME=qt6ct
Debug Messages:
By default, debug messages from platform plugin are disabled. To enable them, you should
export the following environment variable:
export QT_LOGGING_RULES="qt6ct.debug=true"
Another way is to change qtlogging.ini file. See Qt documentation for details:
https://doc.qt.io/qt-6/qloggingcategory.html (paragraph "Configuring Categories")
