QTcpServer no such slot warning

Poldi

I'm trying to figure out why the following code gives a warning that the slot NewTcpServer is not found

#include <QTcpServer>
#include <QTcpSocket>

class TcpServer : public QObject
{
     Q_OBJECT
public:
    static const char *kSettingsGroup;

    explicit TcpServer(QObject *parent = nullptr);
    ~TcpServer();

  bool ServerUp();

public slots:
  void NewTcpConnection();
  void StartServer(QHostAddress ipAddr, int port);
  void StopServer();
  void CreateRemoteClient();


signals:

private:
  QTcpServer *server_;
  QTcpSocket *socket_;
};

#include "core/logging.h"

TcpServer::TcpServer(QObject *parent)
    : QObject{parent}
{
  server_ = new QTcpServer(this);
  connect(server_, SIGNAL(newConnection()),this,SLOT(newTcpConnection()));
}

TcpServer::~TcpServer()
{
}

void TcpServer::StartServer(QHostAddress ipAddr, int port)
{
  bool ok = false;
  qLog(Debug) << "Thread is " << thread();
  ok = server_->listen(ipAddr, port);
  if (ok){
    qLog(Debug) << "Server Started";
  }
}

void TcpServer::NewTcpConnection()
{
  //QTcpSocket *socket = server_->nextPendingConnection();
  socket_ = server_->nextPendingConnection();
  qLog(Debug) << "New Socket";
  qLog(Debug) << socket_->currentReadChannel();
}

I've tried this code in a smal program and it works, but when I do this in a larger app, I get this warning.
Thanks

The case of the slots names as declared needs to match that as used in creating the connection.
newTcpConnection != NewTcpConnection

This type of error is easier to catch with the function pointer versions of QObject::connect().

Dohhhh

Thanks

I changed the code to this and it works

connect(server_,&QTcpServer::newConnection, this, &TcpServer::NewTcpConnection);

Thanks,
