Create a new Qt project of type GUI widget. Follow the procedure given in this article for creating new project.

Now replace the three files named main.cpp, customwidget.h and customwidget.cpp with the code given below.

Main.cpp

#include <QApplication>
 
#include "customwidget.h"
 
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    CustomWidget w;
    w.show();
    return a.exec();
}

customwidget.h

#ifndef CUSTOMWIDGET_H
#define CUSTOMWIDGET_H
 
#include <QWidget>
 
class CustomWidget : public QWidget
{
    Q_OBJECT
 
public:
    CustomWidget(QWidget *parent = 0);
};
 
#endif // CUSTOMWIDGET_H

customwidget.cpp

#include <QPushButton>
#include <QVBoxLayout>
#include <QCoreApplication>
 
#include "customwidget.h"
 
CustomWidget::CustomWidget(QWidget *parent) :
    QWidget(parent)
{
    QVBoxLayout* layout = new QVBoxLayout(this);
 
    // This button show the top level widget in a normal size
    QPushButton* normalSizeButton = new QPushButton("Normal size");
    QObject::connect(normalSizeButton, SIGNAL(clicked()), this, SLOT(showNormal()));
    layout->addWidget(normalSizeButton);
 
    // This button maximize the widget size
    QPushButton* maximzeButton = new QPushButton("Maximize");
    QObject::connect(maximzeButton, SIGNAL(clicked()), this, SLOT(showMaximized()));
    layout->addWidget(maximzeButton);
 
    // This button exit the application
    QPushButton* exitButton = new QPushButton("Exit");
    QObject::connect(exitButton, SIGNAL(clicked()), qApp, SLOT(quit()));
    layout->addWidget(exitButton);
}
