将 Frame 从原始 window 更改为另一个

Question

我有这个函数，每次调用另一个函数时都会生成一个按钮，并将新按钮放入新的 window。我已经成功地将这段代码实现到我的主程序中，除了一个部分，按钮不会在除我的主 window 之外的任何其他 window 中生成。代码有点长，请见谅

import tkinter as tk
from pathlib import Path

def window2():
    editor = tk.Toplevel()
    editor.title("Window 2")
    
def add_buttons(*items):
    for item in items:
        auto_button = tk.Button(button_frame, text=item)
        auto_button.grid(column=1)

def get_items(path):
    if path.exists():
        with open(path, "r") as f:
            data = f.read().strip().splitlines()
            return data
    return []

def save_items(path, items):
    with open(path, "w") as f:
        f.write("\n".join(items))

def submit():
    global items

    # get the text and append it to our global list of button text
    text = entry.get()
    items.append(text)

    # create the button
    add_buttons(text)

    # save the list of items
    save_items(path, items)

root = tk.Tk()
button_frame = tk.Frame(root)
entry = tk.Entry(root)
submit = tk.Button(root, text="Submit", command=submit)

entry.grid(row=0, column=1)
submit.grid(row=1, column=0, columnspan=2)
button_frame.grid(column=1)

window2_btn = tk.Button(root, text="Take me to window 2", command=window2).grid(row=2, column=0,)

# initialize our list of buttons from a file
path = Path("buttons.txt")
items = get_items(path)
add_buttons(*items)

root.mainloop()

我现在已经在 3 个不同的程序中对此进行了测试，所有程序都具有相同的按钮模式，可以在主启动 window 中正常运行，但不允许我调用该函数以在主启动中运行与上文 button_frame = tk.Frame(window) 不同的 window。上面的代码几乎是 Bryan Oakley 的原汁原味，归功于他，我回到他发给我的代码示例中，以显示我的最小值，但有同样的错误。每次调用这个函数时，它都会给出一个未定义的（window 在这个例子中）错误。我知道这不是一个硬性解决方案，但看在我的份上，我一直无法弄清楚。

这是完整的脚本。此代码有效！

from pathlib import Path
import tkinter as tk

def window2():
    window.deiconify()
    window.lift()
    window.title("Window 2")
    window.focus_force()
    
def add_buttons(*items):
    for item in items:
        auto_button = tk.Button(button_frame, text=item)
        auto_button.grid(column=1)

def get_items(path):
    if path.exists():
        with open(path, "r") as f:
            data = f.read().strip().splitlines()
            return data
    return []

def save_items(path, items):
    with open(path, "w") as f:
        f.write("\n".join(items))

def submit():
    global items

    # get the text and append it to our global list of button text
    text = entry.get()
    items.append(text)

    # create the button
    add_buttons(text)

    # save the list of items
    save_items(path, items)

root = tk.Tk()
window = tk.Toplevel()

button_frame = tk.Frame(window)
entry = tk.Entry(root)
submit = tk.Button(root, text="Submit", command=submit)

entry.grid(row=0, column=1)
submit.grid(row=1, column=0, columnspan=2)
button_frame.grid(column=1)

window2_btn = tk.Button(root, text="Take me to window 2", command=window2).grid(row=2, column=0,)

# initialize our list of buttons from a file
path = Path("buttons.txt")
items = get_items(path)
add_buttons(*items)

root.mainloop()
