Whenever we create a GUI program, tkinter generally presents the output screen in the background. In other words, tkinter displays the program window behind other programs. In order to put the tkinter window on top of others, we are required to use attributes('- topmost', True) property. It pulls up the window on the upside.Example#Importing the library from tkinter import * #Create an instance of tkinter window or frame win= Tk() #Setting the geometry of window win.geometry("600x350") #Create a Label Label(win, text= "Hello World!

Read MoreWhat is the difference between root.destroy() and root.quit() in Tkinter(Python)?
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(): ...
