When we invoke the destroy() method with the tkinter window object, it terminates the mainloop process and destroys all the widgets inside the window. Tkinter destroy() method is mainly used to kill and terminate the interpreter running in the background.However, quit() method can be invoked in order to stop the process after the mainloop() function. We can demonstrate the functionalities of both methods by creating a button Object.Example#Import the required libraries from tkinter import * #Create an instance of tkinter frame win= Tk() #Set the geometry of frame win.geometry("650x450") #Define a function for Button Object def quit_win(): ...

tkinter.ttk is a module that is used to style the tkinter widgets. Just like CSS is used to style an HTML element, we use tkinter.ttk to style tkinter widgets.Here are the major differences between tkinter widget and tkinter.ttk −Tkinter widgets are used to add Buttons, Labels, Text, ScrollBar, etc., however, tkinter.ttk supports a variety of widgets as compared to tkinter widgets.Tkinter.ttk doesn't support Place, Pack() and Grid(), thus it is recommended to use tkinter widget with ttk.Ttk has many features and configurations that extend the functionality of a native application and make it look more modern.Tkinter widget is a native ...
