Tkinter toplevel class contains toplevel window which is a child window other than the main window. Whenever we create a toplevel window, it just appears above the main window along with the widgets defined in it.
To keep the window toplevel window focused, we can use grab_set() method. It always keeps the toplevel window above all the other windows.
#Import the tkinter library from tkinter import * #Create an instance of tkinter frame win = Tk() win.geometry("700x350") def open_win(): top = Toplevel(win) top.geometry("700x250") Label(top, text= "Hey Folks!", font= ('Helvetica 14 bold')).pack() top.grab_set() #Create a Label to print the Name label= Label(win, text="Click the below Button to open the Popup", font= ('Helvetica 18 bold')) label.pack(pady= 30) #Create a Button button= Button(win, text= "Click Me", command= open_win, font= ('Helvetica 14 bold'), foreground= 'OrangeRed3', background= "white") button.pack(pady=50) win.mainloop()
Running the above code will display a window that contains a button to open the Popup window.
Now, click the button to open a Popup window.
