destroy() method in Tkinter | Python
Tkinter supports a variety of methods to perform various tasks. It also offers some universal method.
destroy() is a universal widget method i.e we can use this method with any of the available widgets as well as with the main tkinter window.
Syntax:
widget_object = Widget(parent, command = widget_class_object.destroy)
This method can be used with after() method.
Code #1: destroy() method passed as command
# importing only those functions # which are needed from tkinter import * from tkinter.ttk import * # creating tkinter window root = Tk() # Creating button. In this destroy method is passed # as command, so as soon as button 1 is pressed root # window will be destroyed btn1 = Button(root, text ="Button 1", command = root.destroy) btn1.pack(pady = 10) # Creating button. In this destroy method is passed # as command, so as soon as button 2 is pressed # button 1 will be destroyed btn2 = Button(root, text ="Button 2", command = btn1.destroy) btn2.pack(pady = 10) # infinite loop mainloop() |
Output:
As you may observe, in above code that the command that is passed in button-2 is to destroy button-1 so as soon as you press button-2, button-2 will get destroyed.
Code #2:destroy() method with after() method
# importing only those functions # which are needed from tkinter import * from tkinter.ttk import * # creating tkinter window root = Tk() # Creating button. In this destroy method is passed # as command, so as soon as button 1 is pressed root # window will be destroyed btn1 = Button(root, text ="Button 1") btn1.pack(pady = 10) # Creating button. In this destroy method is passed # as command, so as soon as button 2 is pressed # button 1 will be destroyed btn2 = Button(root, text ="Button 2") btn2.pack(pady = 10) # after method destroying button-1 # and button-2 after certain time btn1.after(3000, btn1.destroy) btn2.after(6000, btn2.destroy) # infinite loop mainloop() |
Output:
From output you may see that both the widgets are destroyed after a certain time limit and only root window will be left empty.
Note: There is another method available quit() which do not destroy widgets but it exits the tcl/tk interpreter i.e it stops the mainloop().
