    • reinstallEventNotifyCallback

      public static boolean reinstallEventNotifyCallback()
      This method allows to reinstall the QtJambi event notify callback as the last callback. If other libraries register their event notify callback to Qt, it is necessary to make sure QtJambi's callback is called at last. This method can only be called from inside the main thread and before calling QCoreApplication.exec().

    • saveUnixSignalHandlers

      public static boolean saveUnixSignalHandlers()
      Third-party libraries must not overwrite Java's installed signal handlers. Several of these signal handlers are crucial for JVM to work. This method saves the installed signal handlers for later restoring by restoreUnixSignalHandlers().

    • restoreUnixSignalHandlers

      public static boolean restoreUnixSignalHandlers()
      Third-party libraries must not overwrite Java's installed signal handlers. Several of these signal handlers are crucial for JVM to work. This method restores the signal handlers previously saved by saveUnixSignalHandlers().

      public static QVersionNumber qtjambiVersion()
      Return the version of QtJambi
      Returns:
      qtjambi version
