Ok, so this is from a larger project that I am working on, so I apologize if it looks messy.
The issue is that when I click the 'Exit Program' Button on the GUI, the window remains active. I know that the button is working as when I hit the 'x' on the top right corner the window; the program closes, so the run variable has been set back to 0, which stops the code from looping.
My question is how do I get the window to be closed automatically when the exit button is clicked, because the root.destroy() method isn't doing it.
#imports
from tkinter import *
import random, pickle, shelve
#global vars
run = 0
class Window(Frame):
#the class that manages the UI window
def __init__(self, master, screen_type = 0):
"""Initilize the frame"""
super(Window, self).__init__(master)
self.grid()
if screen_type == 1:
self.log_in_screen()
def log_in_screen(self):
#Program Exit Button
self.exit = Button(self, text = " Exit Program ", command = self.end)
self.exit.grid(row = 3, column = 0, columnspan = 2, sticky = W)
def end(self):
global run, root
run = 0
root.destroy()
#Main Loop
def main():
global run, root
run = 1
while run != 0:
root = Tk()
root.title("Budget Manager - 0.6.1")
root.geometry("400x120")
screen = Window(root, screen_type = run)
root.mainloop()
store = shelve.open("store.dat", "c")
main()
store.close()
My question is how do I get the window to be closed automatically when the exit button is clicked, because the root.destroy() method isn't doing it.
The answer is: call destroy() on the root window. You say it isn't working, but the code you posted seems to work, and what destroy() is documented to do is exactly what you describe you want to have happen: it will destroy the window. Your code creates new toplevel windows in a loop, so maybe it only appears to not work since the old window id destroyed and the new window is created in the blink of an eye.
It seems like what you're really asking is "how can I make clicking on the "x" do the same as clicking on the "Exit program" button?". If that is the case, the answer is very straight-forward, even with your unconventional code that creates root windows in a loop.
To get the "x" button on the window frame to call a function instead of destroying the window, use the wm_protocol method with the "WM_DELETE_WINDOW" constant and the function you want it to call.
For example:
while run != 0:
root = Tk()
...
screen = Window(root, screen_type = run)
root.wm_protocol("WM_DELETE_WINDOW", screen.end)
...
root.mainloop()
