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

介绍页面

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 。 QVBoxLayout is used to hold the label 。此 page is returned when the createIntroPage() 函数被调用。

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;
}

注册页面

The registration page is created with the createRegistrationPage() 函数。 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 对象。

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;
}

结论页面

The conclusion page is created in the createConclusionPage() function. This function's content is similar to createIntroPage() 。 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()` 函数

The main() function instantiates a QWizard 对象， 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[])
{
    QCoreApplication::setAttribute(Qt::AA_UseHighDpiPixmaps);
    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();
}
