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.

Member Function Documentation

QTcpSocket::QTcpSocket(QObject **parent* = nullptr)

Creates a QTcpSocket object in state UnconnectedState.

`[virtual]` QTcpSocket::~QTcpSocket()

Destroys the socket, closing the connection if necessary.
