README

+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://sourceforge.net/projects/qt5ct/
+
+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:
+
+qmake PREFIX=<your installation path>
+make
+make install (under root)
+
+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
+
+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 DISABLE_DBUS=1 - disable D-Bus support (global menu and D-Bus tray icon implementation)
+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-5/qloggingcategory.html (paragraph "Configuring Categories")
