如何在不暂停tkinter中的整个窗口的情况下暂停特定的功能？

import threading
import time
import tkinter as tk

class MyThread(threading.Thread):
    def __init__(self):
        threading.Thread.__init__(self)
        self.paused = False
        self.pause_cond = threading.Condition(threading.Lock())

    def run(self):
        while True:
            with self.pause_cond:
                while self.paused:
                    self.pause_cond.wait()
                # 执行特定功能的代码
                print("特定功能正在执行...")
                time.sleep(1)

    def pause(self):
        self.paused = True

    def resume(self):
        self.paused = False
        with self.pause_cond:
            self.pause_cond.notify()

# 创建主窗口
root = tk.Tk()

# 创建子线程
thread = MyThread()
thread.start()

# 暂停特定功能的按钮回调函数
def pause_func():
    thread.pause()

# 恢复特定功能的按钮回调函数
def resume_func():
    thread.resume()

# 创建暂停和恢复按钮
pause_button = tk.Button(root, text="暂停特定功能", command=pause_func)
pause_button.pack()

resume_button = tk.Button(root, text="恢复特定功能", command=resume_func)
resume_button.pack()

# 运行主窗口的消息循环
root.mainloop()
