Packet Sniffer

This isn't a code fix really more a look for some advice.

Below is the code i have for my socket class. The aim will be to monitor traffic on a chosen interface. i have the list of interfaces listed in my mainwindow.cpp.

I would like to know if im heading in the right direction with the choice of functions and members or have i got it completely wrong. Im not sure QTcpSocket is what i should use, or should i look at the abstract socket. also i have heard about libpcap libraries and tcpdump but im not sure if thats the only option?

@#include "socket.h"
#include "QObject"
#include "QtCore"
#include "QNetworkConfigurationManager"
#include "QNetworkInterface"
#include "QHostAddress"
#include "QString"
#include "QFile"
#include "QLineEdit"
#include "QDir"
#include "QApplication"
#include "QMainWindow"
#include "mainwindow.h"
#include ""

Socket::Socket(QObject *parent) :
QObject(parent),
ui(new Ui::Socket)
{
void Socket::test(){

    socket = new QTcpSocket(this);

    connect(socket,SIGNAL(connected()), this, SLOT(connected()));
    connect(socket,SIGNAL(disconnected()), this, SLOT(disconnected()));
    connect(socket,SIGNAL(readyRead()), this, SLOT(readyRead()));
    connect(socket,SIGNAL(bytesWritten(qint64)), this, SLOT(bytesWritten(qint64)));

    ui->packet->show << "Connecting...";

    socket->connectToInterface("comboBox_Interface",80);

    if (!socket->waitForConnected(3000))
    {
       ui->packet->show << "Error" << socket->errorString();
    }

}

void Socket::connected()
{
    ui->packet->show << "Connected...";
}

void Socket::disconnected()
{
    ui->packet->show << "Disconnected...";
}

void Socket::bytesWritten ( qint64 bytes )
{
    ui->packet->show << "We Wrote..." << bytes;
}

void Socket::readyRead()
{
    ui->packet->show << "Reading...";
    ui->packet->show << socket->readAll;
}

}
}
