QT C++ How can I inform the user after the sQSerialPort reading process is finished?

[TheCeylann]

I have a program that reads data over the serial port. I am collecting the incoming data into a buffer and the incoming data has no fixed value. I want to notify the user after the data is finished reading How can I do this?

Here I check if data is coming through the serial port. How can I check this after all the data is in?

serialInput = serial.getString();
  serial.clearAll();

  serialInput = serialInput.trimmed();

  if (serialInput.isEmpty() == false) {
    parser.parse(serialInput, 0 == 0, 0 == 2); 
    QStringList labelList = parser.getStringListLabels();
    QList < double > numericDataList = parser.getListNumericValues();


    QList < long > timeStamps = parser.getListTimeStamp();

    this -> processChart(labelList, numericDataList, timeStamps);

    this -> saveToRAM(labelList, numericDataList, timeStamps);

  }
}

How do you know that all data is transferred?

After all the data has been sent, if I send another data indicating that the data has been sent, can I do this by checking the latest data?

@TheCeylann When you send data over a stream you have to add some kind of protocol so you know when your data is complete. How you implement it is up to you.
