如何在tkinter中重新评估复选按钮的状态

import tkinter as tk

root = tk.Tk()
var = tk.IntVar()
checkbox = tk.Checkbutton(root, text="复选按钮", variable=var)
checkbox.pack()

state = var.get()

var.set(1)  # 设置复选按钮为选中状态
var.set(0)  # 设置复选按钮为未选中状态

import tkinter as tk

def evaluate_checkbox():
    state = var.get()
    if state == 1:
        print("复选按钮已选中")
    else:
        print("复选按钮未选中")

def set_checkbox_state():
    var.set(1)  # 设置复选按钮为选中状态

root = tk.Tk()
var = tk.IntVar()
checkbox = tk.Checkbutton(root, text="复选按钮", variable=var)
checkbox.pack()

evaluate_button = tk.Button(root, text="评估复选按钮状态", command=evaluate_checkbox)
evaluate_button.pack()

set_state_button = tk.Button(root, text="设置复选按钮为选中状态", command=set_checkbox_state)
set_state_button.pack()

root.mainloop()
