Tkinter is a standard Python library that is used to create and develop GUI-based applications. We can create an application in Tkinter and add widgets to it that make the application more interactive.
Let's suppose we want to show a popup dialog in an application. In this case, we can use the built-in messagebox module in tkinter. It allows us to show the various dialog boxes such as errors, info box, confirmation boxes, etc.
In this example, we've created a button, which upon clicking will show a popup message on the screen.
# Import the required library from tkinter import * from tkinter import ttk from tkinter import messagebox # Create an instance of tkinter frame win=Tk() # Set the geometry win.geometry("700x250") # Define a button to show the popup message box def on_click(): messagebox.showinfo("Message", "Hey folks!") # Add a Label widget Label(win, text="Click the button to open a popup", font=('Georgia 13')) # Create a button to open the popup dialog ttk.Button(win, text="Open Popup", command=on_click).pack(pady=30) win.mainloop()
Running the above code will display a window with a button to open a dialog box.
Click the button to show the popup dialog box on the screen.
