在Tkinter中有没有暂停和恢复线程的方法？

import tkinter as tk
import threading

class App:
    def __init__(self, root):
        self.root = root
        self.is_paused = False
        self.thread = threading.Thread(target=self.run)
        self.thread.start()
        
        self.pause_button = tk.Button(root, text="暂停", command=self.pause_resume_thread)
        self.pause_button.pack()
        
    def run(self):
        while True:
            if not self.is_paused:
                # 执行线程的任务
                print("线程正在运行...")
            
    def pause_resume_thread(self):
        self.is_paused = not self.is_paused
        if self.is_paused:
            self.pause_button.config(text="恢复")
        else:
            self.pause_button.config(text="暂停")

root = tk.Tk()
app = App(root)
root.mainloop()
