Change the size of Tkinter MessageBox

Altering the size of a standard Tkinter messagebox directly isn't straightforward because the messagebox is designed to automatically adjust its size based on its content. However, there are some workarounds that involve creating a custom message box using a Toplevel widget.

If you are okay with creating a custom message box, here's a tutorial to guide you through it:

Create a Custom MessageBox with Specified Size in Tkinter:

Setting up the basic GUI with Tkinter:

Start by creating a basic main window using Tkinter.

import tkinter as tk

root = tk.Tk()
root.title("Custom MessageBox Size")
root.geometry("300x200")

Defining a custom message box function:

Instead of the standard messagebox, we'll create a custom one using the Toplevel widget.

def custom_messagebox(title, message, width=200, height=100):
    top = tk.Toplevel(root)
    top.title(title)
    top.geometry(f"{width}x{height}")

    msg = tk.Label(top, text=message)
    msg.pack(pady=20, padx=20)

    button = tk.Button(top, text="OK", command=top.destroy)
    button.pack(pady=10)

    root.wait_window(top)

The function custom_messagebox allows you to specify the title, message, width, and height for your custom message box.

Create a function to trigger the custom message box:

def show_custom_messagebox():
    custom_messagebox("Custom Info", "This is a custom message box!", width=300, height=150)

Add a button to display the custom message box:

btn = tk.Button(root, text="Show Custom Message", command=show_custom_messagebox)
btn.pack(pady=50)

Run the main loop:
```
root.mainloop()
```

By piecing together the above code snippets and running the script, you'll have a Tkinter window with a button. Pressing the button will present a custom message box with the specified size. You can adjust the width and height parameters in the show_custom_messagebox function to suit your needs.
