使用QWizard做新建向导，最简单的实例

class MyWizard : public QWizard
{
public:

    MyWizard(QWidget* parent = nullptr);

    QWizardPage* createFirstPage();

    QWizardPage* createSecondPage();

    QWizardPage* createThirdPage();
};

MyWizard::MyWizard(QWidget* parent) :
    QWizard(parent)
{
    /*setOption( QWizard::NoBackButtonOnStartPage );*/
    //setOption( QWizard::NoBackButtonOnLastPage );
    //setOption( QWizard::NoCancelButton );

    setOption(QWizard::NoBackButtonOnStartPage);//设置第一页没有上一步的按钮
    setWizardStyle(QWizard::ModernStyle);//设置上一步下一步等按钮的显示格式
    addPage(createFirstPage());//添加自己写好的QWizardPage页面
    addPage(createSecondPage());
    addPage(createThirdPage());
}
QWizardPage* MyWizard::createFirstPage()
{
    QWizardPage* firstPage = new QWizardPage;
    firstPage->setTitle(tr("first"));//设置第一个QWizardPage
    QLabel* picLabel = new QLabel;
    picLabel->setPixmap(QPixmap(":/QtCanpoolDemo/res/1.jpg"));
    QHBoxLayout* firstLayout = new QHBoxLayout;
    firstLayout->addWidget(picLabel);
    firstPage->setLayout(firstLayout);

    firstPage->setButtonText(QWizard::BackButton, "back");
    firstPage->setButtonText(QWizard::NextButton, "next");//为next设置一个中文的名字
    firstPage->setButtonText(QWizard::CancelButton, "cancel");
    firstPage->setButtonText(QWizard::FinishButton, "finish");
    return firstPage;
}
QWizardPage* MyWizard::createSecondPage()
{
    QWizardPage* secondPage = new QWizardPage;
    secondPage->setTitle(tr("second"));
    QLabel* picLabel = new QLabel;
    picLabel->setPixmap(QPixmap(":/QtCanpoolDemo/res/2.jpg"));

    secondLayout->addWidget(picLabel);
    secondPage->setLayout(secondLayout);

    secondPage->setButtonText(QWizard::NextButton, "next");
    secondPage->setButtonText(QWizard::BackButton, "back");
    secondPage->setButtonText(QWizard::CancelButton, "cancel");
    secondPage->setButtonText(QWizard::FinishButton, "finish");
    return secondPage;
}
QWizardPage* MyWizard::createThirdPage()
{

    thirdPage->setButtonText(QWizard::FinishButton, "finish");
    return thirdPage;
}

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

    MyWizard wizard;
    wizard.show();

    return app.exec();
