tkinter 中的框架未彼此堆叠

我在 tkinter 中将“页面”堆叠在一起时遇到问题。

我有一个主Frame包含两个子帧，两个子帧都包含不同的信息。第一个子帧包含Listbox和几个按钮，位于主框架的左侧。第二个框架应该包含不同的“页面”（现在有两个）并让它们填满整个框架。 我的问题是两个“页面”并排显示，而不是彼此重叠。

import tkinter as tk


class Settings(tk.Tk):

    def __init__(self, master=None):
        tk.Tk.__init__(self, master)
        self.focus_force()
        self.grab_set()
        # set focus to settings window
        # Main window title
        self.title("Settings")


        # set up grid containers
        container_main = tk.Frame(self, width=500, height=700)
        container_main.pack(side='top', fill='both', expand=True)
        container_main.grid_rowconfigure(0, weight=1)
        container_main.grid_columnconfigure(0, weight=1)

        container_listbox = tk.Frame(container_main, bg='blue', width=200, height=700)
        container_listbox.pack(side='left', fill='both', expand=True)
        container_listbox.grid_rowconfigure(0, weight=1)
        container_listbox.grid_columnconfigure(0, weight=1)

        container_settings = tk.Frame(container_main, bg='red', width=300, height=700)
        container_settings.pack(side='right', fill='both', expand=True)
        container_settings.grid_rowconfigure(0, weight=1)
        container_settings.grid_columnconfigure(0, weight=1)

        # build settings pages
        self.frames = {}

        self.frames["Options"] = Options(parent=container_listbox, controller=self)
        self.frames["General"] = General(parent=container_settings, controller=self)
        self.frames["Future"] = Future(parent=container_settings, controller=self)

如果我取消注释这两行。我收到一条错误消息，说我无法在内部使用几何管理器网格。

        # self.frames["General"].grid(row=0, column=0, sticky='nsew')
        # self.frames["Future"].grid(row=0, column=0, sticky='nsew')

.

    def show_frame(self, page_name):
        frame = self.frames[page_name]
        frame.tkraise()


class Options(tk.Frame):

    def __init__(self, parent, controller):
        tk.Frame.__init__(self, parent)
        self.controller = controller
        label = tk.Label(parent, text='List Box')
        label.grid(row=0, column=0, sticky='nsew', padx=1, pady=1)
        button1 = tk.Button(parent, text='General', command=lambda: controller.show_frame('General'))
        button2 = tk.Button(parent, text='Future', command=lambda: controller.show_frame('Future'))
        button1.grid(row=1, column=0, sticky='ew')
        button2.grid(row=2, column=0, sticky='ew')


class General(tk.Frame):
    def __init__(self, parent, controller):
        tk.Frame.__init__(self, parent)
        self.controller = controller
        label = tk.Label(parent, text='General')
        label.pack(side='left', fill='both', expand=True, )
        print("Hi I'm General")

class Future(tk.Frame):
    def __init__(self, parent, controller):
        tk.Frame.__init__(self, parent)
        self.controller = controller
        label = tk.Label(parent, text='Future')
        label.pack(side='left', fill='both', expand=True)
        print("Hi I'm Future")

app = Settings()
app.mainloop()

两个“页面”同时初始化并显示，这是有道理的。我只是不知道如何让其中一个超越另一个frame.tkraise()应该这样做，但没有。我也希望能够做到grid_forget()位于不在顶部的一个或多个页面上，以避免将来可能意外地将值输入到隐藏的输入框中。

编辑：如果我注释掉“未来”页面，那么“常规”页面将占据整个框架空间，因此grid_forget()我会得到同样的结果。我只是不知道我会去哪里但是grid_forget()然后我还要在哪里重新配置或执行grid() call?

我的问题是两个“页面”并排显示，而不是彼此重叠。

如果你使用pack()在根窗口上放置一个框架，然后使用grid()在该框架内，那么它会起作用，但是如果您尝试使用pack()框架内部，然后尝试使用grid()在同一框架内它将失败。

根窗口和框架也是如此。如果pack()根窗口中的框架，那么您无法使用grid()将任何内容放入同一个根窗口中。

问题与grid() vs pack()问题是因为上课的地点General和班级Future正在配置标签小部件是父框架，其中pack()正在被使用。这阻止了使用grid()在同一个父框架中放置常规框架和未来框架。

为了解决这个问题，我们改变：

label = tk.Label(parent, text='General')

and

label = tk.Label(parent, text='Future')

to:

label = tk.Label(self, text='General')

and

label = tk.Label(self, text='Future')

上述是使其正常工作所需的唯一修复。
