Python Tkinter用面向对象编程关闭程序并在代码中打开

几天前，我开始用tkinter开发我的System Manager GUI程序，我被选项卡住了。我想从程序内部重新定义应用颜色选项时的所有内容，但我做不到，所以我想到了一个想法，即当前程序窗口关闭，相同窗口打开，但应用了新颜色。所以我设法再次打开那个项目，但现在我不知道如何关闭最后一个。 以下是代码的一部分：

class Menu(tk.Tk):
    def __init__(self, *args, **kwargs):
        tk.Tk.__init__(self, *args, **kwargs)
        container = tk.Frame(self)
        container.pack(side="top", fill="both", expand=True)
        container.grid_rowconfigure(0, weight=1)
        container.grid_columnconfigure(0, weight=1)
        self.frames = {}
        for F in (StartMenu, Settings, Colour):
            frame = F(container, self)
            self.frames[F] = frame
            frame.grid(row=0, column=0, sticky="nsew")
            frame.configure(background="white")
        frame.grid(row=0, column=0, sticky="nsew")
        tk.Tk.wm_title(self, "System Manager")
        tk.Tk.geometry(self, "1500x800+200+100")
        self.show_frame(StartMenu)
    def show_frame(self, cont):

        frame = self.frames[cont]
        frame.tkraise()

        Button4 = tk.Button(self, text="System", font=("Arial", 80), bg=BB[0], activebackground=BB[0], width=7, fg=Color[0])

        Button4.place(x=800, y=200)

不要为错误的缩进感到抱歉，修复它。一般来说，在Tkinter中打开其他窗口是通过。由于示例代码太长且不完整，因此很难进一步帮助您。你可能会在这个页面上发现有趣的东西
