RunTime Execution

[hasnatzaidi]

hey to all, i create the ui Files more than one. At the execution one Ui file call successfully opened by the Pushbutton Clicked. But When I want to open Another Ui file From Previous opened Ui file it can't open. The Code are same, and i include also its header file But it can not work.
Its .cpp file is

#include "sessiondetail.h"
#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QWidget>
#include <QDebug>
#include "ui_2x.h"
#include "ui_mainwindow2.h"
 
sessiondetail::sessiondetail()
{
    connect(ui->btn_s_2x,SIGNAL(clicked()),this,SLOT(on_btn_s_2x_clicked()));
}
// that window open successfully
void MainWindow::on_btn_screate_clicked()
{
Ui::sessiondetail ui;
QMainWindow *sessiondetail = new QMainWindow;
ui.setupUi(sessiondetail);
sessiondetail->show();
}
// this MainWindow2X not be open
void sessiondetail::on_btn_s_2x_clicked()
{
    Ui::MainWindow2X ui;
    QMainWindow *MainWindow2X = new QMainWindow;
    ui.setupUi(MainWindow2X);
    MainWindow2X->show();
}

#include "sessiondetail.h"
#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QWidget>
#include <QDebug>
#include "ui_2x.h"
#include "ui_mainwindow2.h"

sessiondetail::sessiondetail()
{
    connect(ui->btn_s_2x,SIGNAL(clicked()),this,SLOT(on_btn_s_2x_clicked()));
}
// that window open successfully
void MainWindow::on_btn_screate_clicked()
{
Ui::sessiondetail ui;
QMainWindow *sessiondetail = new QMainWindow;
ui.setupUi(sessiondetail);
sessiondetail->show();
}
// this MainWindow2X not be open
void sessiondetail::on_btn_s_2x_clicked()
{
    Ui::MainWindow2X ui;
    QMainWindow *MainWindow2X = new QMainWindow;
    ui.setupUi(MainWindow2X);
    MainWindow2X->show();
}

the header file is

#ifndef SESSIONDETAIL_H
#define SESSIONDETAIL_H
#include <QMainWindow>
#include <QWidget>
namespace Ui
{
    class MainWindow;
    class sessiondetail;
}
class sessiondetail : public QMainWindow
{
 
public:
 
private:
    Ui::sessiondetail *ui;
private slots:
       void on_btn_s_ica_clicked();
 
    void on_btn_s_2x_clicked();
 
};
 
#endif // SESSIONDETAIL_H

#ifndef SESSIONDETAIL_H
#define SESSIONDETAIL_H
#include <QMainWindow>
#include <QWidget>
namespace Ui
{
    class MainWindow;
    class sessiondetail;
}
class sessiondetail : public QMainWindow
{
    
public:
    
private:
    Ui::sessiondetail *ui;
private slots:
       void on_btn_s_ica_clicked();

    void on_btn_s_2x_clicked();

};

#endif // SESSIONDETAIL_H

You forgot to put Q_OBJECT macro in class declaration.
