Qt two or multiple same signals calling slot only once - qt

Question

I'm sending two (or more) same signals, which receives one slot, but it is only called once instead of two times.. What I'm doing wrong?
main.cpp:
#include <QCoreApplication>
#include "app.h"
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
App app;
QMetaObject::invokeMethod(&app, "run", Qt::QueuedConnection);
return a.exec();
}
app.h:
#ifndef APP_H
#define APP_H
#include <QObject>
#include "tcpserver.h"
#include "tcpsocket.h"
class App : public QObject
{
Q_OBJECT
public:
explicit App(QObject *parent = 0);
signals:
public slots:
void run()
{
qDebug() << "run()";
server.server_start(1111);
socket.connectToHost("127.0.0.1", 1111);
socket.write("hello", 5);
socket.write("olleh", 5); // should execute slot two times.
}
private:
TcpServer server;
TcpSocket socket;
};
#endif // APP_H
TcpSocket.h:
#ifndef TCPSOCKET_H
#define TCPSOCKET_H
#include <QTcpSocket>
class TcpSocket : public QTcpSocket
{
Q_OBJECT
public:
explicit TcpSocket(QObject *parent = 0);
signals:
void dataReady(QByteArray data);
public slots:
void readyRead()
{
qDebug() << "Bytes available:" << this.bytesAvailable(); // called only once.
data = this.readAll(); // just for testing.
emit dataReady(data); //
}
void disconnected();
private:
QByteArray data;
};
#endif // TCPSOCKET_H
as you can see, I'm doing two socket.write functions, which should be handled two readyRead slots, but it is called only once. I honestly don't understand what I'm doing wrong.
Regards.
