How to create a multiline entry with tkinter?

To create a multiline entry (text input) widget with Tkinter, you can use the Text widget, which allows users to input and display multiline text. Here's an example of how to create a multiline entry widget in Tkinter:

import tkinter as tk

def get_text():
    text = text_widget.get("1.0", "end-1c")  # Get the text from the Text widget
    print(text)

# Create the main window
root = tk.Tk()
root.title("Multiline Entry Example")

# Create a Text widget
text_widget = tk.Text(root, height=5, width=30)
text_widget.pack(padx=10, pady=10)

# Create a button to get the text
get_text_button = tk.Button(root, text="Get Text", command=get_text)
get_text_button.pack(pady=5)

# Start the Tkinter main loop
root.mainloop()

In this example:

  1. We create a Tkinter main window using tk.Tk() and set its title.

  2. We create a Text widget (text_widget) and specify its height and width to determine the initial size of the widget. The height specifies the number of lines, and the width specifies the number of characters per line.

  3. We create a button (get_text_button) that, when clicked, calls the get_text function to retrieve and print the text from the Text widget.

  4. The get_text function uses the .get("1.0", "end-1c") method to retrieve the text from the Text widget. "1.0" refers to the start position, and "end-1c" refers to the end position minus one character. This ensures that we get all the text without an extra newline character at the end.

  5. Finally, we start the Tkinter main loop with root.mainloop().

When you run this code, you'll see a window with a multiline entry widget and a "Get Text" button. Users can input multiline text in the widget, and clicking the button will print the entered text to the console.

You can further customize the appearance and behavior of the Text widget as needed for your application.
