How to read and write from a qtcpsocket?
When writing to a QTcpSocket multiple times, and flushing the socket each time to send that data, how can I read this from a QTcpSocket as it is send, keep the original “send structure”? The example below only reads the first block and ends. I would like to read the block containing “Response 2” and “Response 3”. //…
How to use qsslsocket as a regular qtcpsocket?
Once encrypted, you use QSslSocket as a regular QTcpSocket. When readyRead () is emitted, you can call read (), canReadLine () and readLine (), or getChar () to read decrypted data from QSslSocket ‘s internal buffer, and you can call write () or putChar () to write data back to the peer.
How does qsslsocket automatically encrypt the written data?
QSslSocket will automatically encrypt the written data for you, and emit encryptedBytesWritten () once the data has been written to the peer. As a convenience, QSslSocket supports QTcpSocket ‘s blocking functions waitForConnected (), waitForReadyRead (), waitForBytesWritten (), and waitForDisconnected ().
What are the functions of the qsslsocket class?
The QSslSocket class provides an SSL encrypted socket for both clients and servers. More… This class was introduced in Qt 4.3. Note: All functions in this class are reentrant. QSslSocket establishes a secure, encrypted TCP connection you can use for transmitting encrypted data.

Which is a subclass of qabstractsocket for TCP?
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. For TCP Socket in general, please visit my C++ Tutorials: Socket – Server and Client.
What causes qtcpsocket to crash in while loop?
I then tried QDataStream::atEnd () in a while loop which causes a system crash : ( The code below shows my latest attempt of going through the QDataStream docs, and utilzing the commitTransaction where it states
Which is the best tutorial for TCP socket?
For TCP Socket in general, please visit my C++ Tutorials: Socket – Server and Client. We’ll start with Qt Console Application. First, we need to add network module to our project file, QTcpSocket.pro:
How to create a TCP connection in Qt?
To create a TCP connection in Qt, we will use QTcpSocket. First, we need to connect with connectToHost. So for example, to connect to a local tcp serveur: _socket.connectToHost(QHostAddress(“127.0.0.1”), 4242); Then, if we need to read datas from the server, we need to connect the signal readyRead with a slot.

Which is slot accepts a qbytearray with data?
QPeer has a slot that accepts a QByteArray with data ( sendData (QByteArray) ). The entire contents of that array are considered to be one ‘message’ and they are written to the socket.
