closing all windows in python tkinter

You are importing tkinter 2 times here. Onces with * and ones as tk.

this will help you avoid overriding anything that other libraries imports or having tkinter’s functions overwritten by other imports.

You have a very unorthodox way of creating your tkinter app but if you wish to keep everything as is here is what you need to change:

Lets remove the cancel button from your quitDialog window and then add a yes and no button. This will server to allow you to either say yes to destroy all windows or to say no to only destroy the quitDialog window.

First we need to add an arguement to your QuitDialog class so we can pass the any window or frame we want to it.

So add the instance argument to your QuitDialog() class like below:

class QuitDialog(): def __init__(self, instance): self.instance = instance 
cancelButton = tk.Button(master= self.quitDialog , text='Cancel', command = self.quitALL).grid(row=2, column=1) 
quitButton = tk.Button(master= self.quitDialog , text='Yes', command = self.quitALL).grid(row=2, column=1) cancelButton = tk.Button(master= self.quitDialog, text='No', command = lambda: self.quitDialog.destroy()).grid(row=2, column=2)

Then lets change your quitALL() method to:

def quitALL(self): self.quitDialog.destroy() self.instance.destroy()

This will use our instance argument to destroy a window we pass in.

Now change your showQuitDialog() method to:

def showQuitDialog(self): quitdialog = QuitDialog(self.mainWindow) quitdialog.start()

As you can see we are now passing the the tk window self.mainWindow to the QuitDialog class so we can decide on weather or not to close it.

Below is the copy past version of your code that should work as you need it to:

import tkinter as tk from tkinter import ttk import tkinter.messagebox import datetime class AlertDialog: def __init__(self): self.invalidDiag = tk.Toplevel() invalidInput = tk.Label(master=self.invalidDiag, text='Error: Invalid Input').grid(row=1, column=1) closeButton = tk.Button(master=self.invalidDiag, text='Close', command=self.invalidDiag.destroy).grid(row=2, column=1) def start(self): # self.invalidDiag.grab_set() #takes control over the dialog (makes it active) self.invalidDiag.wait_window() class QuitDialog(): def __init__(self, instance): self.instance = instance self.quitDialog = tk.Toplevel() warnMessage = tk.Label(master=self.quitDialog, text='Are you sure that you want to quit? ').grid(row=1, column=1, columnspan=2) quitButton = tk.Button(master= self.quitDialog , text='Yes', command = self.quitALL).grid(row=2, column=1) cancelButton = tk.Button(master= self.quitDialog, text='No', command = lambda: self.quitDialog.destroy()).grid(row=2, column=2) def start(self): # self.invalidDiag.grab_set() #takes control over the dialog (makes it active) self.quitDialog.wait_window() def quitALL(self): self.quitDialog.destroy() self.instance.destroy() class TimeConverter: def __init__(self): self.mainWindow = tk.Tk() self.mainWindow.title("Seconds Converter") self.results = tk.StringVar() self.inputSecs = tk.StringVar() secLabel = tk.Label(master=self.mainWindow, text="Seconds:").grid(row=0, sticky="W") resultLabel = tk.Label(master=self.mainWindow, text="Converted Time:\n(H:M:S)").grid(row=1, sticky="W") calcResults = tk.Label(master=self.mainWindow, background='light gray', width=20, textvariable=self.results, anchor="w").grid(row=1, column=1) secEntry = tk.Entry(master=self.mainWindow, width=24, textvariable=self.inputSecs).grid(row=0, column=1) calcButton = tk.Button(master=self.mainWindow, text='Calculate', command=self.SecondsToHours).grid(row=2, column=0, sticky="w") quitButton = tk.Button(master=self.mainWindow, text='Quit', command=self.showQuitDialog).grid(row=3, column=1, sticky="E") def invalidInputEntered(self): errorDiag = AlertDialog() errorDiag.start() def showQuitDialog(self): quitdialog = QuitDialog(self.mainWindow) quitdialog.start() def startDisplay(self) -> None: self.mainWindow.mainloop() def destroyit(self): self.mainWindow.destroy() def SecondsToHours(self): try: inputseconds = int(self.inputSecs.get()) seconds = int(inputseconds % 60) minutes = int(((inputseconds - seconds) / 60) % 60) hours = int((((inputseconds - seconds) / 60) - minutes) / 60) tempResults = str(hours) + ':' + str(minutes) + ':' + str(seconds) self.results.set(tempResults) return except ValueError: self.invalidInputEntered() #self.showQuitDialog() if __name__ == '__main__': TimeConverter().startDisplay()

Interesting question. As I know, you can also use just quit() in order to quit from program by closing everything.
