The QTcpServer class provides a TCP-based server.
This class makes it possible to accept incoming TCP connections. You can specify the port or have QTcpServer pick one automatically. You can listen on a specific address or on all the machine's addresses.
Call listen() to have the server listen for incoming connections. The newConnection() signal is then emitted each time a client connects to the server.
Call nextPendingConnection() to accept the pending connection as a connected QTcpSocket. The function returns a pointer to a QTcpSocket in QAbstractSocket::ConnectedState that you can use for communicating with the client.
If an error occurs, serverError() returns the type of error, and errorString() can be called to get a human readable description of what happened.
When listening for connections, the address and port on which the server is listening are available as serverAddress() and serverPort().
Calling close() makes QTcpServer stop listening for incoming connections.
Although QTcpServer is mostly designed for use with an event loop, it's possible to use it without one. In that case, you must use waitForNewConnection(), which blocks until either a connection is available or a timeout expires.
Symbian Platform Security Requirements
On Symbian, processes which use this class must have the NetworkServices platform security capability. If the client process lacks this capability, it will lead to a panic.
Platform security capabilities are added via the TARGET.CAPABILITY qmake variable.

| QtNetwork.QTcpServer.QTcpServer | ( | QObject | parent = null | ) |
Constructs a QTcpServer object.
parent is passed to the QObject constructor.
See also listen() and setSocketDescriptor().
|
protected |
This function is called by QTcpServer::incomingConnection() to add the socket to the list of pending incoming connections.
Note: Don't forget to call this member from reimplemented incomingConnection() if you do not want to break the Pending Connections mechanism.
This function was introduced in Qt 4.7.
See also incomingConnection().
| new void QtNetwork.QTcpServer.Close | ( | ) |
Closes the server. The server will no longer listen for incoming connections.
See also listen().
|
virtual |
Reimplemented from QtCore.QObject.
| new void QtNetwork.QTcpServer.Dispose | ( | ) |
| new string QtNetwork.QTcpServer.ErrorString | ( | ) |
Returns a human readable description of the last error that occurred.
See also serverError().
|
virtual |
Returns true if the server has a pending connection; otherwise returns false.
See also nextPendingConnection() and setMaxPendingConnections().

protectedvirtual |
This virtual function is called by QTcpServer when a new connection is available. The socketDescriptor argument is the native socket descriptor for the accepted connection.
The base implementation creates a QTcpSocket, sets the socket descriptor and then stores the QTcpSocket in an internal list of pending connections. Finally newConnection() is emitted.
Reimplement this function to alter the server's behavior when a connection is available.
If this server is using QNetworkProxy then the socketDescriptor may not be usable with native socket functions, and should only be used with QTcpSocket::setSocketDescriptor().
Note: If you want to handle an incoming connection as a new QTcpSocket object in another thread you have to pass the socketDescriptor to the other thread and create the QTcpSocket object there and use its setSocketDescriptor() method.
See also newConnection(), nextPendingConnection(), and addPendingConnection().
| new bool QtNetwork.QTcpServer.IsListening | ( | ) |
Returns true if the server is currently listening for incoming connections; otherwise returns false.
See also listen().
| new bool QtNetwork.QTcpServer.Listen | ( | ) |
Tells the server to listen for incoming connections on address address and port port. If port is 0, a port is chosen automatically. If address is QHostAddress::Any, the server will listen on all network interfaces.
Returns true on success; otherwise returns false.
See also isListening().
| new bool QtNetwork.QTcpServer.Listen | ( | QHostAddress | address, |
| ushort | port = 0 |
||
| ) |
Tells the server to listen for incoming connections on address address and port port. If port is 0, a port is chosen automatically. If address is QHostAddress::Any, the server will listen on all network interfaces.
Returns true on success; otherwise returns false.
See also isListening().
|
virtual |
Returns the next pending connection as a connected QTcpSocket object.
The socket is created as a child of the server, which means that it is automatically deleted when the QTcpServer object is destroyed. It is still a good idea to delete the object explicitly when you are done with it, to avoid wasting memory.
0 is returned if this function is called when there are no pending connections.
Note: The returned QTcpSocket object cannot be used from another thread. If you want to use an incoming connection from another thread, you need to override incomingConnection().
See also hasPendingConnections().
|
protected |
This signal is emitted every time a new connection is available.
See also hasPendingConnections() and nextPendingConnection().
| new QHostAddress QtNetwork.QTcpServer.ServerAddress | ( | ) |
Returns the server's address if the server is listening for connections; otherwise returns QHostAddress::Null.
See also serverPort() and listen().
| new QAbstractSocket.SocketError QtNetwork.QTcpServer.ServerError | ( | ) |
Returns an error code for the last error that occurred.
See also errorString().
| new ushort QtNetwork.QTcpServer.ServerPort | ( | ) |
Returns the server's port if the server is listening for connections; otherwise returns 0.
See also serverAddress() and listen().
| new bool QtNetwork.QTcpServer.SetSocketDescriptor | ( | int | socketDescriptor | ) |
Sets the socket descriptor this server should use when listening for incoming connections to socketDescriptor. Returns true if the socket is set successfully; otherwise returns false.
The socket is assumed to be in listening state.
See also socketDescriptor() and isListening().
| new int QtNetwork.QTcpServer.SocketDescriptor | ( | ) |
Returns the native socket descriptor the server uses to listen for incoming instructions, or -1 if the server is not listening.
If the server is using QNetworkProxy, the returned descriptor may not be usable with native socket functions.
See also setSocketDescriptor() and isListening().

| new bool QtNetwork.QTcpServer.WaitForNewConnection | ( | int | msec = 0 | ) |
Waits for at most msec milliseconds or until an incoming connection is available. Returns true if a connection is available; otherwise returns false. If the operation timed out and timedOut is not 0, *timedOut will be set to true.
This is a blocking function call. Its use is disadvised in a single-threaded GUI application, since the whole application will stop responding until the function returns. waitForNewConnection() is mostly useful when there is no event loop available.
The non-blocking alternative is to connect to the newConnection() signal.
If msec is -1, this function will not time out.
See also hasPendingConnections() and nextPendingConnection().
| new bool QtNetwork.QTcpServer.WaitForNewConnection | ( | int | msec, |
| ref bool | timedOut | ||
| ) |
Waits for at most msec milliseconds or until an incoming connection is available. Returns true if a connection is available; otherwise returns false. If the operation timed out and timedOut is not 0, *timedOut will be set to true.

getprotected |
|
getset |
Returns the maximum number of pending accepted connections. The default is 30.
Sets the maximum number of pending accepted connections to numConnections. QTcpServer will accept no more than numConnections incoming connections before nextPendingConnection() is called. By default, the limit is 30 pending connections.
Clients may still able to connect after the server has reached its maximum number of pending connections (i.e., QTcpSocket can still emit the connected() signal). QTcpServer will stop accepting the new connections, but the operating system may still keep them in queue.

addremove |
This signal is emitted every time a new connection is available.
See also hasPendingConnections() and nextPendingConnection().
|
getset |
Returns the network proxy for this socket. By default QNetworkProxy::DefaultProxy is used.
This function was introduced in Qt 4.1.
Sets the explicit network proxy for this socket to networkProxy.
To disable the use of a proxy for this socket, use the QNetworkProxy::NoProxy proxy type:
server->setProxy(QNetworkProxy::NoProxy);
This function was introduced in Qt 4.1.
