# Trivial Wizard Example

Files:

- dialogs/trivialwizard/trivialwizard.cpp

The Trivial Wizard example illustrates how to create a linear three-page registration wizard using three instances of QWizardPage and one instance of QWizard.

## 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);

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

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

         return app.exec();
     }
