How to Close a Tkinter Window With a Button

We can use a function or command attached to a Tkinter button in the Tkinter GUI to close the Tkinter window when the user clicks it.

root.destroy() Class Method to Close the Tkinter Window

try:
    import Tkinter as tk
except:
    import tkinter as tk


class Test:
    def __init__(self):
        self.root = tk.Tk()
        self.root.geometry("100x50")
        button = tk.Button(self.root, text="Click and Quit", command=self.quit)
        button.pack()
        self.root.mainloop()

    def quit(self):
        self.root.destroy()


app = Test()

destroy() method destroys or closes the window. We make a separate quit method and then bind it to the command of the button.

We could also directly set the command argument to be self.root.destroy as below.

try:
    import Tkinter as tk
except:
    import tkinter as tk


class Test:
    def __init__(self):
        self.root = tk.Tk()
        self.root.geometry("100x50")
        button = tk.Button(self.root, text="Click and Quit", command=self.root.destroy)
        button.pack()
        self.root.mainloop()

    def quit(self):
        self.root.destroy()


app = Test()

Tkinter close a window with a button

destroy() Non-Class Method to Close the Tkinter Window

try:
    import Tkinter as tk
except:
    import tkinter as tk

root = tk.Tk()
root.geometry("100x50")


def close_window():
    root.destroy()


button = tk.Button(text="Click and Quit", command=close_window)
button.pack()

root.mainloop()

Associate root.destroy Function to the command Attribute of the Button Directly

We could directly bind root.destroy function to the button command attribute without defining the extra function close_window any more.

try:
    import Tkinter as tk
except:
    import tkinter as tk

root = tk.Tk()
root.geometry("100x50")

button = tk.Button(text="Click and Quit", command=root.destroy)
button.pack()

root.mainloop()

root.quit to Close the Tkinter Window

root.quit quits not only the Tkinter Window but, more precisely, the whole Tcl interpreter.

It could be used if your Tkinter app is not initiated from Python IDLE. We don’t recommend to use root.quit if your Tkinter app is called from IDLE because quit will kill not only your Tkinter app but also the IDLE because IDLE is also a Tkinter application.

try:
    import Tkinter as tk
except:
    import tkinter as tk

root = tk.Tk()
root.geometry("100x50")

button = tk.Button(text="Click and Quit", command=root.quit)
button.pack()

root.mainloop()
