How to add scrollbar in Tkinter – Python

In this tutorial, we will explore how to add a scrollbar to your Python applications built with the Tkinter framework.

Scroll bar widget in Tkinter

In my earlier tutorial, I explained how to add a horizontal scrollbar in Tkinter to your Python applications. Since you already know how to add a scrollbar horizontally, you have to change the orientation, axis, and a couple of parameters in your text widget to implement a vertical scrollbar. Let’s see what parameters require the change.

• Firstly, you have to change the wrap="word" parameter. If you keep it to “none,” it will not print in new lines.
• Now, you have to change the orientation and axis of the scrollbar widget. Keep the orient = "vertical" and change the view to .yview. Also, change the fill parameter to fill= "y".

import tkinter as tk

root = tk.Tk()
root.title("Vertical Scrollbar Example")

text_widget = tk.Text(root, wrap="word")
text_widget.pack(side="left", fill="both", expand=True)

v_scroll = tk.Scrollbar(root, orient="vertical", command=text_widget.yview)
v_scroll.pack(side="right", fill="y")

text_widget.config(yscrollcommand=v_scroll.set)

for i in range(50):
    text_widget.insert("end", "Row " + str(i) + "\n")

root.mainloop()

Output
