Tkinter | TypeError: __init__() takes from 1 to 2 positional arguments but 3 were given

Question

代码旨在从 tkinter 条目小部件 cam1 获取输入并分配给 cam1_name，然后将其附加到一个列表及其关联的回调 function。显然，它不会并抛出上述错误。 任何帮助，将不胜感激。 谢谢！

import tkinter as tk
from tkinter import ttk

root = tk.Tk()    # my main window

def cam1_name_func():
    cam1_name.get()
    amendations["camOne"] = cam1_name

cam1_name = tk.StringVar()
cam1 = ttk.Checkbutton(root, cam1_name).pack()  # error happens on this line

root.mainloop()

Answer 1

要修复该错误，您需要为Checkbutton的第二个参数使用 text 关键字。 Checkbutton 的所有选项都需要在父Checkbutton参数之后列为key=value 。

import tkinter as tk
from tkinter import ttk

root = tk.Tk()    # my main window

def cam1_name_func():
    cam1_name.get()
    amendations["camOne"] = cam1_name

cam1_name = tk.StringVar()
cam1 = ttk.Checkbutton(root, text=cam1_name).pack()

root.mainloop()
