I want to move a widget inside of a canvas with a click of a button. Unfortunatly I always get the same Error:”_tkinter.TclError: invalid boolean operator in tag search expression”

I’ve isolated the false Code:

import tkinter as tk

root = tk.Tk()
w = tk.Canvas(root, width=200, height=200)
w.pack()


def button():
    w.coords(checkbutton, 0, 0, 75, 25)


test = tk.BooleanVar()
checkbutton = tk.Checkbutton(w, text="example", variable=test, width=20, anchor="w")
w.create_window((100, 100), window=checkbutton)
button = tk.Button(w, text="Click", command=button)
button.place(x=50, y=50)
root.mainloop()

I’ve also triede the .configure method without any succsess.

Please help me if you have any suggestions.

Thanks in advance!
