使用 Tkinter 时线程停止循环

Question

我的代码如下。它意味着当用户单击 CTRL + X 时弹出一个 tkinter 窗口，并在按下 CTRL + A 时关闭该窗口。问题是当窗口在打开后关闭时，lookForKeys 中的 while 循环会停止。

import tkinter as tk
from threading import Thread
import keyboard as k

running = False


def main():
    global root
    print('Opening...')
    root = tk.Tk()
    root.geometry("340x740+1550+50")
    root.title('Custom Mic')
    root.resizable(0,0)    
    root.attributes('-topmost', True)
    root.update()

    root.mainloop()

def closeOverlay():
    print('Closing...')
    root.destroy()
    root.quit()


def openOverlay():
    global overlayThread
    print('Opening...')
    overlayThread = Thread(target = main)
    overlayThread.start()

def lookForKeys():
    global running

    while True:
        print(running)
        if k.is_pressed("ctrl+x") and running == False:
            running = True
            openOverlay()

        if k.is_pressed("ctrl+a") and running == True:
            running = False
            closeOverlay()

if __name__ == "__main__":
    mainThread = Thread(target = lookForKeys)
    mainThread.start()

感谢任何帮助。

我将函数 closeOverlay 放在一个线程中，它工作了。

        if k.is_pressed("ctrl+a") and running == True:
            running = False
            closeOverlayThread = Thread(target=closeOverlay)
            closeOverlayThread.start()
