We have a kind of:

connect(socket, SIGNAL(readyRead()), this, SLOT(readyReadImp()))

where let say slot ReadyReadImp() is implemented by using qtcpsocket class. Let say that I want to implement Same code in plainly C++ object. Let say that I have an old code in C++ only, so I wish to incorporate old code. Can I do it? How? And still to use benefits of signal and slots...
