Managing multiple windows in tkinter

In this tutorial, we will learn how to work with multiple windows in tkinter, a popular GUI toolkit for Python. By creating multiple windows, we can build more complex and interactive user interfaces for our applications.

To get started, make sure you have Python installed on your computer. You can check if you have Python installed by opening a terminal or command prompt and typing python --version. If you don’t have Python installed, you can download it from the official website (https://www.python.org/).

Once you have Python installed, you can install tkinter by running the following command in your terminal or command prompt:

pip install tk

Now that we have tkinter installed, we can start creating multiple windows by following the steps below:

Step 1: Import the tkinter module
First, we need to import the tkinter module at the beginning of our script. This will give us access to all the functions and classes we need to create our windows.

import tkinter as tk

Step 2: Create the main window
Next, we will create the main window of our application using the Tk class from tkinter. This window will serve as the parent window for our other windows.

root = tk.Tk()
root.title("Main Window")

Step 3: Create a button to open a new window
Now, we will add a button to the main window that, when clicked, will open a new window. We can achieve this by creating a function that creates a new window and binding it to the button.

def open_window():
    new_window = tk.Toplevel(root)
    new_window.title("New Window")

button = tk.Button(root, text="Open New Window", command=open_window)
button.pack()

Step 4: Add widgets to the new window
In the open_window function, we can add widgets to the new window to make it more interactive. For example, we can add a label and a button to the new window.

def open_window():
    new_window = tk.Toplevel(root)
    new_window.title("New Window")

    label = tk.Label(new_window, text="Hello, this is a new window!")
    label.pack()

    close_button = tk.Button(new_window, text="Close", command=new_window.destroy)
    close_button.pack()

Step 5: Run the application
Finally, we need to start the tkinter event loop to display the main window and allow user interaction.

root.mainloop()

That’s it! You have now successfully created a tkinter application with multiple windows. You can further customize your windows by adding more widgets, such as entry fields, radio buttons, check boxes, and more. Experiment with different layouts and styles to create a user-friendly interface for your application.
