    have you installed a translator loading your translation file?

  • @raven-worx of course i did. the tr("") QString in a Class which is derived from QObject and have Q_OBJECT marco in the header works fine...
    but the global did not work...

    then the global variable gets initialized before you install the translator.
    When a new translator gets installed all tr() calls need to be reevaluated, means need to get called again.
    Actually you need to listen to a QEvent::LanguageChange event (on the QApplication itself IIRC) and then update the values again.

    It probably works in a QObject class because you instantiate the class after you installed the translator?
