空白 'tk' window 当程序是 运行 从运行导入程序的按钮弹出时 |对于 Tkinter
Blank 'tk' window popping up when program is ran from a button which runs an imported program | For Tkinter
所以我有这个启动程序，我希望它是一个导入的程序，同时销毁启动程序。但是，当我这样做时，导入的程序会运行，但还会在程序中弹出一个空白 'tk' window 。有人知道如何解决这个问题吗？
这是启动程序的代码：
from tkinter import *
from stopwatch import Main
root = Tk()
def launch():
root.destroy()
Main()
launchbutton = Button(root, text='Launch Program', command=launch)
launchbutton.pack()
root.mainloop()
这是导入模块的代码：
from tkinter import *
import time
def Main():
global root
root = Toplevel()
width = 600
height = 200
screen_width = root.winfo_screenwidth()
screen_height = root.winfo_screenheight()
x = (screen_width / 2) - (width / 2)
y = (screen_height / 2) - (height / 2)
root.geometry("%dx%d+%d+%d" % (width, height, x, y))
root.title("Stopwatch")
Top = Frame(root, width=600)

您错误地将秒表 window 设置为 Toplevel()。这会导致 Tk() window 打开。所以当你使用 Toplevel() 时，一个 Tk() window 也应该存在。
