所以我试图为我开发的Tkinter应用程序创建主菜单,但是当我单击按钮上的一个打开另一个文件(另一个窗口也可以)时,这就是问题,但是当我关闭该窗口时并尝试通过在主菜单中单击同一按钮再次将其打开,我会收到此错误:
Exception in Tkinter callback
Traceback (most recent call last):
File "c:\users\alireza\anaconda3\Lib\tkinter\__init__.py", line 1702, in __call__
return self.func(*args)
File "menu.py", line 32, in open_main
root.destroy()
File "c:\users\alireza\anaconda3\Lib\tkinter\__init__.py", line 2059, in destroy
self.tk.call('destroy', self._w)
_tkinter.TclError: can't invoke "destroy" command: application has been destroyed
这是我的主菜单文件(menu.py):
from tkinter import *
import tkinter.messagebox
class Application:
def __init__(self, master, *args, **kwargs):
self.mainframe = Frame(master, width = 300, height = 400, bg = 'slategray1')
self.mainframe.pack()
self.main_button = Button (self.mainframe, width = 25, height = 2,bg = "SteelBlue2" , text = "Customer Service", command = self.open_main)
self.main_button.place(x= 55, y =50 )
self.add_to_db_button = Button (self.mainframe, width = 25, height = 2,bg = "SteelBlue2" , text = "Add Item To Inventory", command = self.open_add_to_db)
self.add_to_db_button.place(x= 55, y =100 )
self.update_button = Button (self.mainframe, width = 25, height = 2,bg = "SteelBlue2" , text = "Update Inventory Items", command = self.open_update)
self.update_button.place(x= 55, y =150 )
self.about_button = Button (self.mainframe, width = 25, height = 2,bg = "sea green" , text = "Credits", command = self.about)
self.about_button.place(x= 55, y =300 )
self.close_button = Button (self.mainframe, width = 25, height = 2,bg = "navajo white" , text = "Quit", command = self.close_window)
self.close_button.place(x= 55, y =350 )
def close_window(self, *args, **kwargs):
root.destroy()
def open_main(self, *args, **kwargs):
import main
root.destroy()
def open_add_to_db(self, *args, **kwargs):
import add_to_db
root.destroy()
def open_update(self, *args, **kwargs):
from update import AppUpdate
root.destroy()
def about(self, *args, **kwargs):
tkinter.messagebox.showinfo("About Me", "Programmed and designed by Alireza Bagheri.")
root = Tk()
root.title("Main Menu")
root.resizable(False, False)
b = Application(root)
root.geometry("301x401+0+0")
root.mainloop()
我不太清楚问题出在哪里,所以将我指向正确的方向很重要
