[SOLVED] Qt Example - QNetwork

? Offline

Hello, I am playing around with "Qt example":http://qt-project.org/doc/qt-5.0/qtnetwork/torrent-peerwireclient-cpp.html and there is one thing I don't really understand...

How are readFromSocket and readData emited? I did not find it being called anywhere... I am trying to understand how to read incoming data from socket...

@qint64 PeerWireClient::readFromSocket(qint64 bytes)
{
char buffer[1024];
qint64 totalRead = 0;
do {
qint64 bytesRead = socket.read(buffer, qMin<qint64>(sizeof(buffer), bytes - totalRead));
if (bytesRead <= 0)
break;
qint64 oldSize = incomingBuffer.size();
incomingBuffer.resize(oldSize + bytesRead);
memcpy(incomingBuffer.data() + oldSize, buffer, bytesRead);

    totalRead += bytesRead;
} while (totalRead < bytes);

if (totalRead > 0) {
    downloadSpeedData[0] += totalRead;
    emit bytesReceived(totalRead);
    processIncomingData();
}
return totalRead;

}@

@qint64 PeerWireClient::readData(char *data, qint64 size)
{
int n = qMin<int>(size, incomingBuffer.size());
memcpy(data, incomingBuffer.constData(), n);
incomingBuffer.remove(0, n);
return n;
}@

These are not signals and they are not emitted.
readFromSocket is called by RateController::transfer() which is called by a timer
readData, "according the the doc":http://qt-project.org/doc/qt-5/qiodevice.html#readData is called by QIODevice
