在其中一個視圖中，有一個用于關(guān)閉實際視圖的按鈕，它可以工作，但當我再次嘗試打開該視圖時，它會顯示下一個錯誤：Exception in Tkinter callback

Traceback (most recent call last):

File "/usr/lib/python2.7/lib-tk/Tkinter.py", line 1545, in __call__

return self.func(*args)

File "/home/htm97/Documents/data/workspace/repositories/projects-h/locker-system/src/gui/MainMenu.py", line 27, in verify_lockers_window

self.app = vl.Lockers(self.vlWindow)

File "/home/htm97/Documents/data/workspace/repositories/projects-h/locker-system/src/gui/Lockers.py", line 19, in __init__

self.buttonsList[i].grid(columnspan = 4)

File "/usr/lib/python2.7/lib-tk/Tkinter.py", line 2032, in grid_configure

+ self._options(cnf, kw))

TclError: bad window path name ".140687059771120.140687059776216.140687059776504.140687059776576"

銷毀窗口的功能是：def close_windows(self):

"This function destroys the window"

self.master.destroy()

這是視圖：import Tkinter as tk

class Lockers:

lockerList = ["1", "2", "3", "4", "5"]

buttonsList = []

def __init__(self, master):

self.master = master

self.frame = tk.Frame(self.master)

self.master.minsize(width = 250, height = 200)

self.initialize_lockers()

self.frame.grid()

tk.Label(self.frame, text = "Seleccione el locker que desea revisar:").grid(row = 0, columnspan = 4)

i = 0

while i < len(self.lockerList):

self.buttonsList[i].grid(columnspan = 4) #HERE THE ERROR

i += 1

tk.Label(self.frame, text = "").grid(columnspan = 4)

self.quitButton = tk.Button(self.frame, text = 'Salir', width = 8, command = self.close_windows)

self.quitButton.grid(column = 1, columnspan = 2)

函數(shù)initialize_lockers()將一些按鈕追加到buttonsList。

在閱讀了一段時間之后，我發(fā)現(xiàn)在執(zhí)行destroy()并嘗試網(wǎng)格化某些內(nèi)容之后，它將顯示一個錯誤，但我不明白為什么。

總結(jié)
