But the clock didn't move, it just showed the current clock.Compilation runs with the following results：

Hi @Qt_HuangZiHan,

you need to change your header like this:

private:
    Ui::HomePage *ui;

    QTimer *new_timer;

    void InitializeForm();
    void InitializeForm_Time();
    void Counter();

private slots:
    void ShowCurrentTime();
};

Don't forget to run Build > Run Qmake afterwards, then build your project.
