如何等待用户单击带有线程的tkinter按钮

import tkinter as tk
import threading

class MyWindow(tk.Tk):
    def __init__(self):
        super().__init__()
        self.button = tk.Button(self, text="点击按钮", command=self.button_click)
        self.button.pack()

    def button_click(self):
        # 创建一个新线程执行需要等待的任务
        thread = threading.Thread(target=self.wait_for_click)
        thread.start()

    def wait_for_click(self):
        # 创建一个事件对象
        event = threading.Event()

        def on_click():
            # 用户单击按钮时，触发事件
            event.set()

        # 在主线程中创建一个临时窗口，并监听按钮点击事件
        temp_window = tk.Toplevel()
        temp_button = tk.Button(temp_window, text="请单击按钮", command=on_click)
        temp_button.pack()

        # 等待事件触发
        event.wait()

        # 事件触发后执行的代码
        print("用户单击了按钮")

if __name__ == "__main__":
    window = MyWindow()
    window.mainloop()
