#include "ui_mainwindow.h"
#include <QTcpServer>
#include <QTcpSocket>
#include <QMessageBox>
#include <QDebug>static int PORT_NUMBER=23;
static int WAIT_FOR_DATA_MS = 200;
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow),
m_server(new QTcpServer(this)),
m_socket(nullptr){
ui->setupUi(this); ui->btnstopserver->setEnabled(false); connect(m_server, QTcpServer::newConnection,this, &MainWindow::ExchangeData);}
MainWindow::~MainWindow()
{
delete ui;
}void MainWindow::on_btnstartserver_clicked()
{
if( startserver())
{
ui->btnstartserver->setEnabled(false);
ui->btnstopserver->setEnabled(true);
}
}
void MainWindow::on_btnstopserver_clicked()
{
stopserver();
ui->btnstartserver->setEnabled(true);
ui->btnstopserver->setEnabled(false);
}
bool MainWindow::startserver()
{
bool result = m_server->listen(QHostAddress::Any, PORT_NUMBER);
if (!result)
{
QMessageBox:: critical(this,tr("EchoServer"),tr("unable to start server:%1").arg(m_server->errorString()));
return false;
}
return true;
}
void MainWindow::stopserver()
{
m_server->close();
if((m_socket!= nullptr) &&m_socket->isOpen())
{
m_socket->close();
}
}
void MainWindow ::ExchangeData()
{
m_socket = m_server->nextPendingConnection();
if (m_socket->isOpen())
{
connect(m_socket, &QTcpSocket::readyRead,this, &MainWindow::EchoReadData);
}}
void MainWindow ::EchoReadData()
{
m_socket->write("<echoserver>\n");
QString result;
while(!m_socket->atEnd())
{
result.append(m_socket->readAll());
m_socket->waitForReadyRead(WAIT_FOR_DATA_MS);}m_socket->write(qPrintable(result));
m_socket->write("\n</echoserver>\n");
qDebug() << "hey";}

Hi,
You should take a look a the network examples.
You are also triggering possibly blocking loop that will not allow to do anything else in your application.
