Whenever we run a tkinter application, it displays a GUI-based window that would have widgets, frames, and other elements. Let us suppose we want to close our application with a function. The destroy() method in Python tkinter is used to terminate the normal execution of the application after the mainloop function.
In this example, will create a button object which triggers to close the application.
#Import the tkinter library from tkinter import * #Create an instance of tkinter frame win = Tk() #Set the geometry win.geometry("650x250") #Define a function def close_app(): win.destroy() #Create a text Label Label(win, text= "Click to close the Window", font= ('Helvetica bold', 14)).pack(pady=20) #Create a Button for closing the window button= Button(win, text= "Close", command= close_app, font=('Helvetica bold', 10)) button.pack(pady=10) win.mainloop()
Running the above code will display a window that contains a button that can be used to close the window.
Now, you can click on the “Close” button to close the window.
