Tkinter - Text Widget

In this tutorial we will talk about Tkinter Text Widget. Make sure that you can run this source, and than we will explain.

Please note, we are reading a textual file LICENCE.txt, which is located in Python install folder - this script must be in a folder where that txt file resides, too. You can set a path to some other txt file.

from tkinter import *
import tkinter.messagebox as mb
import os

top_win = Tk()
top_win.geometry("800x800")

file = open("LICENSE.txt", "r")

t = Text(top_win, padx = 20, pady = 20, width = 50, height = 20,
         cursor = "dot", relief = RIDGE, bd = 10, bg = "lightyellow",
         fg = "red", selectbackground = "yellow", selectforeground = "black",
         font = "Verdana")

for x in file.read():
    t.insert(END, x)

file.close()
t.pack(side = TOP, anchor = NW)
top_win.mainloop()

This is line that will open LICENCE.txt for reading:

file = open("LICENSE.txt", "r")

And this is source for Text Widget. We have padding set, width and height set, type of cursor, type of relief, border width, background color, text color, font type is Verdana, and background and foreground color set when we select part of text:

t = Text(top_win, padx = 20, pady = 20, width = 50, height = 20,
         cursor = "dot", relief = RIDGE, bd = 10, bg = "lightyellow",
         fg = "red", selectbackground = "yellow", selectforeground = "black",
         font = "Verdana")

With for loop we are reading txt file content. Otherwise you will not see any text on screen, just borders and colors:

for x in file.read():
    t.insert(END, x)

This line will close file:

file.close()

As with other widgets we must pack our text section, and at the end of script is standard mainloop:

t.pack(side = TOP, anchor = NW)
top_win.mainloop()
