QTcpSocket 'connected()' signal issue

[anda_skoa]

There is some inconsistency in your posting:

I wanted to do an action when an incoming connection to the server is established from a client.

This sounds like you are writing server code.

while "socket" is is a pointer to QTcpSocket :

socket = new QTcpSocket;

socket = new QTcpSocket;

To copy to clipboard, switch view to plain text mode 

while this is clearly client code.

For a client the connect should work, i.e. the slot should be invoked when the socket establishes a connection to the server.
For a server, the client is already connected (it has connected to the server after all), so the socket is already in "connection established" state.
