如何从 tkinter 复选框中删除勾号

Question

有两个复选框。当一个被勾选时，我需要另一个去掉它的勾号，假设它被勾选了。我该怎么做？

我尝试延迟禁用和启用复选框，但它们会恢复到初始状态(如果勾选，则保持勾选状态(。

from tkinter import *

def removetickwoman():
    # something to remove the tick from woman

def removetickman():
    # something to remove the tick from man

root = Tk()
chkvar1 = IntVar()
chkvar2 = IntVar()

check1 = Checkbutton(root, text="man", variable=chkvar1, command=removetickwoman)
check1.pack()
check2 = Checkbutton(root, text="woman", variable=chkvar2, command=removetickman)
check2.pack()
root.mainloop()

是的，这不仅是可能的，而且已经由tkinter提出：您需要使用RadioButton而不是CheckButton：

import tkinter as tk

root = tk.Tk()    
MODES = [("Man", "M"), ("Woman", "W")]
v = tk.StringVar()
v.set("M")
for text, mode in MODES:
    b = tk.Radiobutton(root, text=text,
                    variable=v, value=mode)
    b.pack(anchor=tk.W)
root.mainloop()
