琐碎向导示例

Trivial Wizard 示例说明了如何使用QWizardPage 的三个实例和QWizard 的一个实例创建线性三页注册向导。

介绍页面

介绍页面使用createIntroPage() 函数创建，其中创建了一个QWizardPage ，并将其标题设为 "Introduction"（介绍）。QLabel 用于保存page 的说明。QVBoxLayout 用于保存label 的说明。调用createIntroPage() 函数时将返回page 。

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

createRegistrationPage() QLineEdit 对象用于让用户输入姓名和电子邮件地址。 用于保存 和 对象。QGridLayout QLabel QLineEdit 

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

结论页面通过createConclusionPage() 函数创建。该函数的内容与createIntroPage() 类似。QLabel 用于通知用户注册过程已成功完成。

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

main() 函数实例化了一个QWizard 对象、wizard ，并添加了所有三个QWizardPage 对象。wizard 窗口标题设置为 "Trivial Wizard"，并调用其show() 函数来显示该窗口。

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

#ifndef QT_NO_TRANSLATION
    QString translatorFileName = QLatin1String("qtbase_");
    translatorFileName += QLocale::system().name();
    QTranslator *translator = new QTranslator(&app);
    if (translator->load(translatorFileName, QLibraryInfo::path(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();
}
