Объект, созданный в main.cpp не виден в Chat.cpp
Вот мой недокод
1) Chat.h
#pragma once
#include <QtWidgets/QMainWindow>
#include "ui_chat.h"
#include <QTcpServer>
#include <QTcpSocket>
class Chat : public QMainWindow
{
Q_OBJECT
public:

void ShowMessage(QString Message);
private:

};

{
Q_OBJECT
public:
explicit MyServer(QObject* parent = 0);
QTcpServer* server;
signals:
public slots:

};
2) Chat.cpp

}
void MyServer::newConnection() {

socket->write("Kind of connected");
socket->flush();
}
void MyServer::onRead(QString mes) {
w.ShowMessage(mes);
}
void Chat::ShowMessage(QString Message) {
ui.plainTextEdit->insertPlainText(Message);
}
3)Main.cpp

#include <QtGui>
int main(int argc, char *argv[])

Простой
