Read int from Arduino

[gtpt]

Hi:

I want to read and write an int from Arduino.
I'm using "QSerialPort":http://qt-project.org/doc/qt-5.1/qtserialport/qserialport.html and so far Qt only receives "garbage" form Arduino.

The code from Arduino is:
@
int myDelay = 1000;

void setup()
{
Serial.begin(9600);
}

void loop()
{ while (Serial.available() <= 0)
{
Serial.print(myDelay);
}
myDelay = Serial.read();
Serial.flush();
}
@

This read and sends data from Qt.
Sender from Qt:
@void Dialog::enviarAtraso(int valor)
{
serial->write(QString::number(ui->atraso->value()).toLocal8Bit());
// ????
}@

Reader from Qt:
@void Dialog::readResponse()
{
response->append(serial->readAll());
int x = 33; //sample value
// response to int here
// ...
// ...
ui->recebido->setText(QString::number(x));
response->clear();
}@

response is a QByteArray.

Any sugestion in order to establish this communication?
Thanks

bq. Any sugestion in order to establish this communication?

Read documentation, look examples.

Perhaps i did not make my self clear!
My question is about datatypes and converting them into/from QByteArray.
The communication is working fine ...
