Cannot Open QTcpServer No Such File Or Directory

[EverydayDiesel]

Hello I am trying to write my first application in QT and I seem to be stuck.

I have added network to the .pro file....

Exact error is
"mainwindow.cpp:3: error: C1083: Cannot open include file: 'QTcpServer': No such file or directory"

//.pro file
@
QT += core gui network

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = mytestapp
TEMPLATE = app

SOURCES += main.cpp
mainwindow.cpp

HEADERS += mainwindow.h

FORMS += mainwindow.ui
@

//mainwindow.h
@
#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>

namespace Ui {
class MainWindow;
}

class QTcpServer;

class MainWindow : public QMainWindow
{
Q_OBJECT

public:
explicit MainWindow(QWidget *parent = 0);
~MainWindow();

private:
Ui::MainWindow *ui;
QTcpServer *m_server;
};

#endif // MAINWINDOW_H

@

mainwindow.cpp
@
#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QTcpServer>

MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow),
m_server(new QTcpServer(this))
{
ui->setupUi(this);
}

MainWindow::~MainWindow()
{
delete ui;
}

Hi, welcome to devnet.

You need to re-run qmake for it to pick up the changes in .pro file. Go to Build->Run qmake. Now it should compile.
