# Trivial Wizard Example

## Introduction Page

The introduction page is created with the `createIntroPage()` function where a QWizardPage is created and its title is set to "Introduction". A QLabel is used to hold the description of `page`. A QVBoxLayout is used to hold the `label`. This `page` is returned when the `createIntroPage()` function is called.

      QWizardPage *createIntroPage()
      {
          QWizardPage *page = new QWizardPage;
          page->setTitle("Introduction");

          QLabel *label = new QLabel("This wizard will help you register your copy "
                                     "of Super Product Two.");
          label->setWordWrap(true);

          QVBoxLayout *layout = new QVBoxLayout;
          layout->addWidget(label);
          page->setLayout(layout);

          return page;
      }

## Registration Page

The registration page is created with the `createRegistrationPage()` function. QLineEdit objects are used to allow the user to input a name and an e-mail address. A QGridLayout is used to hold the QLabel and QLineEdit objects.

      QWizardPage *createRegistrationPage()
      {
          QWizardPage *page = new QWizardPage;
          page->setTitle("Registration");
          page->setSubTitle("Please fill both fields.");

          QLabel *nameLabel = new QLabel("Name:");
          QLineEdit *nameLineEdit = new QLineEdit;

          QLabel *emailLabel = new QLabel("Email address:");
          QLineEdit *emailLineEdit = new QLineEdit;

          QGridLayout *layout = new QGridLayout;
          layout->addWidget(nameLabel, 0, 0);
          layout->addWidget(nameLineEdit, 0, 1);
          layout->addWidget(emailLabel, 1, 0);
          layout->addWidget(emailLineEdit, 1, 1);
          page->setLayout(layout);

          return page;
      }

## Conclusion Page

The conclusion page is created in the `createConclusionPage()` function. This function's content is similar to `createIntroPage()`. A QLabel is used to inform the user that the registration process has completed successfully.

      QWizardPage *createConclusionPage()
      {
          QWizardPage *page = new QWizardPage;
          page->setTitle("Conclusion");

          QLabel *label = new QLabel("You are now successfully registered. Have a "
                                     "nice day!");
          label->setWordWrap(true);

          QVBoxLayout *layout = new QVBoxLayout;
          layout->addWidget(label);
          page->setLayout(layout);

          return page;
      }

## `main()` Function

The `main()` function instantiates a QWizard object, `wizard`, and adds all three QWizardPage objects to it. The `wizard` window title is set to "Trivial Wizard" and its `show()` function is invoked to display it.

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

      #ifndef QT_NO_TRANSLATION
          QString translatorFileName = QLatin1String("qt_");
          translatorFileName += QLocale::system().name();
          QTranslator *translator = new QTranslator(&app);
          if (translator->load(translatorFileName, QLibraryInfo::location(QLibraryInfo::TranslationsPath)))
              app.installTranslator(translator);
      #endif

          QWizard wizard;
          wizard.addPage(createIntroPage());
          wizard.addPage(createRegistrationPage());
          wizard.addPage(createConclusionPage());

          wizard.setWindowTitle("Trivial Wizard");
          wizard.show();

          return app.exec();
      }
