Solved "No such signal TcpServer" error in QObject::connect

[Coop4Free]

Hello guys,

I tried to script a tcp server and I've almost done it. But right now I'm getting an error in my console output which says:

QObject::connect: No such signal QTcpServer::receiveRequest()
Server started!

And I don't know how to fix that. I hope you guys can help me with it. Thanks for all answers!
Here is my code:

//TcpServer.hpp
#ifndef TCPSERVER_HPP
#define TCPSERVER_HPP

#include <QObject>
#include <QTcpServer>
#include <QTcpSocket>

class TcpServer : public QObject
{
    Q_OBJECT
public:
    explicit TcpServer(QObject *parent = nullptr);

signals:

public slots:
    void receiveRequest();
    void sendData(long long);

private:
    QTcpServer *server;
};
#endif // TCPSERVER_HPP

//TcpServer.cpp
#include "TcpServer.hpp"
#include "ServerUi.hpp"
#include <QDebug>
#include <string>
#include <iostream>

static QTcpSocket *socket;

TcpServer::TcpServer(QObject *parent) : QObject(parent)
{
    server = new QTcpServer(this);
    connect(server, SIGNAL(receiveRequest()), this, SLOT(receiveRequest()));
    if(!server->listen(QHostAddress::Any, 1234))
    {
        qDebug() << "Server could not start!";
    }
    else
    {
        qDebug() << "Server started!";
    }
}

void TcpServer::receiveRequest()
{
    std::string receivedRequest;
    socket = server->nextPendingConnection();
    socket->waitForReadyRead(1000);
    receivedRequest = socket->readAll().toStdString();

    if(receivedRequest == "get270value")
    {
        sendData270();
    }
}

void TcpServer::sendData(long long label270) {
    const char* convertedLabel = reinterpret_cast<char * const>(label270);
    socket->write(convertedLabel);
}

@Coop4Free
easy enough, connect your receiveRequest slot to an signal that actually exists in the QTcpServer - Class

you have the following options:

• acceptError(QAbstractSocket::SocketError socketError)
• void newConnection()
• void destroyed(QObject *obj = nullptr)
• void objectNameChanged(const QString &objectName)

@J-Hilk said in "No such signal TcpServer" error in QObject::connect:

newConnection

It works, thank you very much!
