qt5ct - Qt5 Configuration Tool

This program allows users to configure Qt5 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 >= 5.4.0
- qtsvg >= 5.4.0 (For svg icons)
- qttools >= 5.4.0 (For build only)


Installation:

qmake PREFIX=<your installation path>
make
make install (under root)

Add line 'export QT_QPA_PLATFORMTHEME=qt5ct' to ~/.profile and re-login.
Alternatively, create the file /etc/X11/Xsession.d/100-qt5ct with
the following line:

export QT_QPA_PLATFORMTHEME=qt5ct

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 (libqt5ct.so and libqt5ct-style.so)

Debug Messages:

By default, platform plugin prints debug information to stderr. To disable this behaviour, you should
export the following environment variable:

export QT_LOGGIN_RULES="qt5ct.debug=false"

Another way is to change qtlogging.ini file. See Qt documentation for details:
https://doc.qt.io/qt-5/qloggingcategory.html (paragraph "Configuring Categories")
