Tkinter ScrolledText
Summary: in this tutorial, you’ll learn how to use the Tkinter ScrolledText widget which consists of a Text widget and a vertical Scrollbar widget.
Introduction to the Tkinter ScrolledText widget
So far, you’ve learned how to create a Text widget and how to link a vertical Scrollbar to the text widget.
To make it more convenient, Tkinter provides you with the ScrolledText widget which does the same things as a text widget linked to a vertical scroll bar.
To use the ScrolledText widget, you need to import the ScrolledText class from the tkinter.scrolledtext module.
Technically, the ScrolledText class inherits from the Text class.
The ScrolledText widget uses a Frame widget inserted between the container and the Text widget to hold the Scrollbar widget.
Therefore, the ScrolledText has the same properties and methods as the Text widget. In addition, the geometry manager methods including pack, grid, and place are restricted to the Frame.
Tkinter ScrolledText widget example
The following program illustrates how to create a ScrolledText widget:
import tkinter as tk
from tkinter.scrolledtext import ScrolledTextroot = tk.Tk()
root.title("ScrolledText Widget")
st = ScrolledText(root, width=50, height=10)
st.pack(fill=tk.BOTH, side=tk.LEFT, expand=True)
root.mainloop()
Code language: JavaScript (javascript)
Output:
How it works.
- First, import the
tkintermodule and theScrolledTextclass from thetkinter.scrolledtextmodule. - Second, create the root window and set its title to
'ScrolledText Widget'. - Third, create a new
ScrolledTextwidget and display it on the root window. - Finally, start the main loop.
Here’s the same program but written using the object-oriented programming approach:
import tkinter as tk
from tkinter.scrolledtext import ScrolledTextclass App(tk.Tk):
def __init__(self):
super().__init__()
self.title("ScrolledText Widget")
st = ScrolledText(self, width=50, height=10)
st.pack(fill=tk.BOTH, side=tk.LEFT, expand=True)
if __name__ == "__main__":
app = App()
app.mainloop()
Code language: Python (python)
Summary
- Use the Tkinter
ScrolledTextwidget to create aTextwidget with a verticalScrollbar.
