 root.geometry('170x60')  # 设置窗口大小
 v = tk.StringVar()

     ck['text'] = v.get()

 '''窗体控件'''
 # 标题显示
 lab = tk.Label(root, text='开关状态：', font='宋体 -16')
 lab.grid(row=0, sticky=tk.W)

 # 多选框
 ck = tk.Checkbutton(root, variable=v, text='OFF', font='宋体 -18',
                     onvalue='ON', offvalue='OFF',
                     command=click_event)
