仅使用网格 Tkinter 但仍然收到 TclError

Question

所以我刚开始使用 Google Colab，但一直收到此错误：

TclError: cannot use geometry manager grid inside . which already has slaves managed by pack

我正在尝试制作一个 GUI 窗口来接收用户的信息并保存它。

我在网上阅读的所有内容都表明问题在于我使用的是pack() 和grid()，但我只使用了grid()。当我第一次尝试放置标签时，错误就开始了 (sourceLabel)。

我很困惑，任何帮助都会很棒。

这是您在这里遇到的一个非常奇怪的错误，我只是使用 canvas 和 pack 方法重写了您的代码，而不是网格、行和列。只要确保您使用的是 Python3x 就不会出现这些奇怪的错误，希望这会有所帮助，您可以在底部使用 x 和 y 值，并且可以在我们设置时弄乱顶部的高度和宽度值画布。编码愉快！

from tkinter import *

global path, source, recoding  # Global Values so that save_info can get the values
# Creates window
root = Tk()
root.title("File Information")

# Canvas Creates the base layer for the window, so instead of l = Label(text="Test").grid(row=2, column=3)
# We would now do l = Label(text="Test") 
# canvas.create_window(20, 30, anchor="nw", window=l)
canvas = Canvas(width=400, height=300)
canvas.pack(fill="both", expand=True)
# Canvas.pack() just finishes creating the canvas.

# This program opens the file with information and adds the new information to it.
def save_info():
    global path, source, recoding
    value = path.get()
    loc = source.get()
    recode = recoding.get()
    # change name of file and will this make them see everything
    # f = open("./info.txt", "a+")
    # f.write("Source Data File Location: " + loc + ", Complete File Path: " + value + ", Is recoding of column names and/or values desired?: " + recode)
    # f.flush()
    # f.seek(0)
    # content = f.read()
    # print (content)
    finalList = [value, loc, recode]
    # f.close()
    root.withdraw()
    print(finalList)
    return finalList


sourceLabel = Label(
    text="Source Data File Location:",
    width=21,
    height=2)

pathLabel = Label(
    text="Complete File Path:",
    width=20,
    height=2)

recoding_label = Label(
    text="Is recoding of column \n names and/or values \n desired:",
    width=20,
    height=4)

source = StringVar(root)
source.set("Local")  # default value
sourceOption = OptionMenu(root, source, "Local", "Google Drive", "One Drive")

path = Entry(fg="black", bg="white", width=35)

recoding = StringVar(root)
recoding.set("Yes")  # default value
recodingOption = OptionMenu(root, recoding, "Yes", "No")

button = Button(
    text="Click to Save",
    width=10,
    height=1,
    bg="white",
    fg="black", command=save_info
)

# Since we are now using canvas, we must add all the elements using canvas.create_window, the first int is the x value, 2nd is the y
# Just leave anchor always as nw, and windows need to equal the variable of the widget they need to add
canvas.create_window(0, 50, anchor="nw", window=sourceLabel)
canvas.create_window(0, 90, anchor="nw", window=pathLabel)
canvas.create_window(0, 140, anchor="nw", window=recoding_label)

canvas.create_window(150, 50, anchor="nw", window=sourceOption)
canvas.create_window(150, 90, anchor="nw", window=path)
canvas.create_window(150, 140, anchor="nw", window=recodingOption)
canvas.create_window(150, 225, anchor="nw", window=button)
root.mainloop()

# I refactored some of the variables so they would be unique
