重新启动键盘监听器

Question

我用tkinter制作了一个GUI，您可以在其中指定两个热键。它具有活动和不活动按钮，它们从pynput启动键盘监听器。当使用按钮将启动设置为活动状态时，我想用两个选择的键重新启动键盘监听器。

from tkinter import *
import threading
from pynput.keyboard import Key, Controller
from pynput import keyboard

state = False
key1 = "Shift"
key2 =  "a"

def on_activate():
    global state
    if state == True:
        #do stuff

#keyboard listener
def reading():
    global key1
    global key2
    combination = "<"+key1+">+"+key2
    print(combination)
    with keyboard.GlobalHotKeys({
            combination: on_activate}) as h:
        print(keyboard.GlobalHotKeys)
        h.join()
#dropdown change key1   
def updateKey1(key):
    global key1
    key1 = key
    print("updated key1: " + key1)

#dropdown change key2
def updateKey2(key):
    global key2
    key2 = key
    print("updated key2: " + key2)

#button on  
def turn_on():
    global state
    state = True
        
#button off
def turn_off():
    global state
    state = False
    
hotkey_thread = threading.Thread(target=reading, daemon=True)
    
if __name__ == '__main__':
    hotkey_thread.start()
    window.mainloop()```

因此，我设法使用listener.join（）停止了侦听器，但是GUI没有响应。 这样是正确的尝试吗？有没有办法用新的键重新启动侦听器？
