CODE WITH IMPLEMENTING class WidgetDemo

from tkinter import *
from tkinter import messagebox

#class WidgetDemo
class WidgetDemo():
        #__init__ method
        def __init__(self):
                #creating window
                window = Tk()

                window.title("Widgets Demo!")
                
                #creating frame in window
                frame1 = Frame(window)
                frame1.pack()
                
                #creating button with call to processButton() method
                button1 = Button(text = "Click Here", command = self.processButton)
                button1.pack()
                
                #mainloop
                window.mainloop()
                
        #processButton() method to display "Welcome" using messagebox
