43-
44 \brief The QTcpServer class provides a TCP-based server.-
45-
46 \reentrant-
47 \ingroup network-
48 \inmodule QtNetwork-
49-
50 This class makes it possible to accept incoming TCP connections.-
51 You can specify the port or have QTcpServer pick one-
52 automatically. You can listen on a specific address or on all the-
53 machine's addresses.-
54-
55 Call listen() to have the server listen for incoming connections.-
56 The newConnection() signal is then emitted each time a client-
57 connects to the server.-
58-
59 Call nextPendingConnection() to accept the pending connection as-
60 a connected QTcpSocket. The function returns a pointer to a-
61 QTcpSocket in QAbstractSocket::ConnectedState that you can use for-
62 communicating with the client.-
63-
64 If an error occurs, serverError() returns the type of error, and-
65 errorString() can be called to get a human readable description of-
66 what happened.-
67-
68 When listening for connections, the address and port on which the-
69 server is listening are available as serverAddress() and-
70 serverPort().-
71-
72 Calling close() makes QTcpServer stop listening for incoming-
73 connections.-
74-
75 Although QTcpServer is mostly designed for use with an event-
76 loop, it's possible to use it without one. In that case, you must-
77 use waitForNewConnection(), which blocks until either a-
78 connection is available or a timeout expires.-
