how to find the right socket

[LeoC]

Hey guys,

I have the following code:

com_PingTest::com_PingTest(QList<QHostAddress> lIPAddresses, QObject *parent) : QObject(parent)
{
    for(int iItr = 0; iItr < lIPAddresses.length(); iItr++) {
        QUdpSocket *sNewUDPsocket = new QUdpSocket(this);
        if(sNewUDPsocket->bind(lIPAddresses.at(iItr),1234))
            qDebug() << lIPAddresses.at(iItr).toString() << "good";
        else
            qDebug()<< lIPAddresses.at(iItr).toString() << "not good";
        connect(sNewUDPsocket,SIGNAL(readyRead()),this,SLOT(readyRead()));
        lOfUDPSockets.append(sNewUDPsocket);
    }
}

Now, how do I know which socket has called the readyRead - function?
Is there a possibility to get the socket descriptor of the socket that emitted the readyRead signal?

Thanks!

@LeoC Simple: call sender() inside your slot which returns a pointer to the sender object. Then cast the pointer to QUdpSocket.

• add #include <functional>
• change the readyRead() slot to readyRead(QUdpSocket* socket)
• change connect(sNewUDPsocket,SIGNAL(readyRead()),this,SLOT(readyRead())); to connect(sNewUDPsocket,&QUdpSocket::readyRead,this,std::bind(&com_PingTest::readyRead,this,sNewUDPsocket));
