QT : 받은 메세지를 Char로 그리고 Hex 로 출력

void Widget::readMessage()

{

    int count = 0;

    unsigned char* hex; /* 밥법 1 */

    char* pData;        /* 방법 2 */

     if(tcpSocket->bytesAvailable() >= 0)

    {

        QByteArray readData = tcpSocket->readAll();

        ui->textEdit->append(readData);

        /* change to CHAR */

        count = readData.size();

        hex =new unsigned char[count];

        memcpy(hex,readData.constData(),count);

        pData = readData.data();

        for(int i = 0; i < readData.size(); i++)

        {

            unsigned int j = readData.at(i);

            qDebug() << QString("readData.at 0x%1").arg((int)j, 0, 16);

            qDebug() << QString("pData 0x%1").arg((int)pData[i], 0, 16);

            qDebug() << QString("hex 0x%1").arg((int)hex[i], 0, 16);

            ui->textEdit->append(QString("0x%1").arg((int)j, 0, 16));

        }

        ui->textEdit->append(QString(readData.toHex(':')));

     }

     // disconnect from TCP server

     tcpSocket->disconnectFromHost();

     ui->textEdit->append(QString("Disconnect from Host"));
