Function to close the window in Tkinter

Function to close the window in Tkinter

To create a function that closes a Tkinter window, you can use the destroy() method of the Tkinter window object. Here's an example of how to define a function to close a Tkinter window:

import tkinter as tk def close_window(): root.destroy() # Close the main Tkinter window # Create a Tkinter window root = tk.Tk() # Create a button that calls the close_window function when clicked close_button = tk.Button(root, text="Close Window", command=close_window) close_button.pack() # Run the Tkinter main loop root.mainloop()

In this example:

  1. We define a close_window function that calls the destroy() method on the root window object. This will close the main Tkinter window.

  2. We create a Tkinter window (root) and a button (close_button) that, when clicked, will call the close_window function.

  3. The close_button is displayed in the window using pack().

  4. We start the Tkinter main loop with root.mainloop(), which keeps the window open until the user closes it or the program exits.

When you click the "Close Window" button, the close_window function is called, and it closes the Tkinter window using destroy().

Examples

  1. Tkinter function to close window with button click
    Description: Demonstrates how to create a button in Tkinter that closes the window when clicked.

    import tkinter as tk def close_window(): root.destroy() root = tk.Tk() button = tk.Button(root, text="Close Window", command=close_window) button.pack() root.mainloop()

    This code creates a button labeled "Close Window" using Tkinter, and when clicked, it calls the close_window function, which closes the Tkinter window.

  2. Tkinter function to close window with menu option
    Description: Shows how to add a menu option in Tkinter that closes the window when selected.

    import tkinter as tk def close_window(): root.destroy() root = tk.Tk() menu = tk.Menu(root) root.config(menu=menu) file_menu = tk.Menu(menu) menu.add_cascade(label="File", menu=file_menu) file_menu.add_command(label="Exit", command=close_window) root.mainloop()

    In this code, a menu option labeled "Exit" is added to the "File" menu. When selected, it calls the close_window function to close the Tkinter window.

  3. Tkinter function to close window with keyboard shortcut
    Description: Illustrates how to define a keyboard shortcut to close the Tkinter window.

    import tkinter as tk def close_window(event=None): root.destroy() root = tk.Tk() root.bind("<Control-q>", close_window) root.mainloop()

    Here, pressing Ctrl+Q will trigger the close_window function, which closes the Tkinter window.

  4. Tkinter function to close window on window close event
    Description: Shows how to bind the close event of the Tkinter window to a function that closes it.

    import tkinter as tk def close_window(): root.destroy() root = tk.Tk() root.protocol("WM_DELETE_WINDOW", close_window) root.mainloop()

    This code binds the close event of the Tkinter window to the close_window function, ensuring that clicking the close button of the window closes it.

  5. Tkinter function to close window after certain time
    Description: Demonstrates how to close the Tkinter window automatically after a specified duration.

    import tkinter as tk def close_window(): root.destroy() root = tk.Tk() root.after(5000, close_window) # Close window after 5 seconds (5000 milliseconds) root.mainloop()

    In this code, the close_window function is scheduled to be called after 5 seconds using the after method of the Tkinter window.

  6. Tkinter function to close window with confirmation dialog
    Description: Shows how to display a confirmation dialog before closing the Tkinter window.

    import tkinter as tk from tkinter import messagebox def close_window(): if messagebox.askokcancel("Quit", "Do you want to close the window?"): root.destroy() root = tk.Tk() root.protocol("WM_DELETE_WINDOW", close_window) root.mainloop()

    Here, a confirmation dialog is displayed when attempting to close the window. If the user confirms, the window is closed; otherwise, it remains open.

  7. Tkinter function to close window with custom button text
    Description: Illustrates how to create a button with custom text to close the Tkinter window.

    import tkinter as tk def close_window(): root.destroy() root = tk.Tk() button = tk.Button(root, text="Quit", command=close_window) button.pack() root.mainloop()

    This code creates a button labeled "Quit", which, when clicked, calls the close_window function to close the Tkinter window.

  8. Tkinter function to close window with mouse double-click
    Description: Shows how to bind a double-click event to close the Tkinter window.

    import tkinter as tk def close_window(event): root.destroy() root = tk.Tk() root.bind("<Double-Button-1>", close_window) root.mainloop()

    Here, double-clicking the mouse inside the Tkinter window will trigger the close_window function, closing the window.

  9. Tkinter function to close window after certain action
    Description: Demonstrates closing the Tkinter window after a specific action, such as a button click.

    import tkinter as tk def close_window(): root.after(3000, root.destroy) # Close window after 3 seconds root = tk.Tk() button = tk.Button(root, text="Close Window", command=close_window) button.pack() root.mainloop()

    In this code, after clicking the button labeled "Close Window", the Tkinter window will close automatically after 3 seconds.

  10. Tkinter function to close window with escape key
    Description: Illustrates how to bind the escape key to close the Tkinter window.

    import tkinter as tk def close_window(event): root.destroy() root = tk.Tk() root.bind("<Escape>", close_window) root.mainloop()

    Pressing the Escape key while the Tkinter window is focused will trigger the close_window function, closing the window.
