Detailed Description

The QTcpSocket class provides a TCP socket.

TCP (Transmission Control Protocol) is a reliable, stream-oriented, connection-oriented transport protocol. It is especially well suited for continuous transmission of data.

QTcpSocket is a convenience subclass of QAbstractSocket that allows you to establish a TCP connection and transfer streams of data. See the QAbstractSocket documentation for details.

Note: TCP sockets cannot be opened in QIODevice::Unbuffered mode.

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 result in a panic.

Platform security capabilities are added via the TARGET.CAPABILITY qmake variable.

See also QTcpServer, QUdpSocket, QFtp, QNetworkAccessManager, Fortune Server Example, Fortune Client Example, Threaded Fortune Server Example, Blocking Fortune Client Example, Loopback Example, and Torrent Example.
