You can do [ "en", "fr" ] or { "en": "English", "fr": "French" } however
they are object types in Javascript thus not allowed as settings values.QSettings has support for arrays in the C++ API http://qt-project.org/doc/qt-4.8/qsettings.html#beginWriteArray It should be possible to extend the backend so that it detects arrays and stores them as such. As a short-term solution you could use a string instead like "en,fr". ciao, Christian
