int main(int argc, char *argv[])
{
QApplication a(argc, argv);

// create main window
QMainWindow *mainwindow = new QMainWindow() ;

// create main widget
QWidget *mainwidget = new QWidget() ;

// create button
QPushButton *button = new QPushButton("Button") ;
button->setFixedWidth(200) ;

// create stacked widget and add button
QStackedWidget *stack = new QStackedWidget() ;
stack->addWidget(button) ;
stack->setCurrentIndex(0);

// create layout
QHBoxLayout *mainlayout = new QHBoxLayout() ;
mainlayout->setMargin(5) ;
mainlayout->addWidget(stack) ;
mainwidget->setLayout(mainlayout) ;
mainwindow->setCentralWidget(mainwidget) ;
mainwindow->show();


return a.exec();

}

Hi and welcome to the forums
Your code is almost as expected, except you add the button as the actual Page.
It's more likely you want a QWidget with a layout and then insert buttons to that layout.
ELse BUtton is the page which is kinda odd :)
So its much like you do with the mainwidget.

Can I ask why you don't want to use UI(designer form class ) file?
You can both use UI file and code and actually, UI file is just code that is run in the
setupUI() function.

Reason i am not using Qt designer is, i am developing a application in which one page is having 400 radio button it is easy for me to develop a logic to handle 400 radio buttons when i do not use Qt designer.
So please help me to navigate between pages using QStackedWidget when button is clicked.
