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

Code is meant to take the input from the tkinter entry widget, cam1, and assign to cam1_name, to then be appended to a list with its associated callback function. Obviously, it does not and throws the error above. Any help would be appreciated. Thanks!


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()

CodePudding user response：

To fix the error, you need to use the text keyword for the second argument of Checkbutton. All the options for Checkbutton need to be listed as key=value after the parent window argument.

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()
