      @QtUninvokable public static QtMessageHandler qInstallMessageHandler(QtMessageHandler handler, QtMsgType... supportedMessageTypes)

      Installs the specified message handler as a receiver for message notification.

      Optionally, you can specify all message types treated by the handler to improve performance. All message types not specified here remain hidden. Without specifying any message type here, all message types are sent to the handler.

    • qInstallExceptionMessageHandler

      @QtUninvokable public static QtMessageHandler qInstallExceptionMessageHandler(QtMsgType... supportedMessageTypes)

      Installs an exception-throwing message handler as a receiver for message notification.

      Optionally, you can specify all message types treated by the handler to improve performance. All message types not specified here remain hidden. Without specifying any message type here, all message types are sent to the handler.

      Alternatively, you can use the following Java VM argument to let QtJambi install an exception-throwing message handler:

      -Dio.qt.exceptions-for-messages=TYPE

      where TYPE is either ALL or a combination of CRITICAL, DEBUG, FATAL, WARNING and INFO.

      Alternatively, you can use the following Java VM argument to let QtJambi install a Java logging message handler:

      -Dio.qt.log-messages=TYPE

      where TYPE is either ALL or a combination of CRITICAL, DEBUG, FATAL, WARNING and INFO.
