将表格格式的文本打印到 tk.Text 小部件中，而不是按预期对齐

Question

I couldn't found answer on the internet so I'm hoping you can help me. I'm trying to print from a list into a text box in Tkinter. From some reason, when I print it to text box it's not aligned as its supposed to be but when I print it to the console, its aligned correctly.

Data that I'm using you can find on data .

Any of you knows what might be the problem?

from tkinter import *

popup = Tk()
popup.wm_title("Podaci mreze")
widthTabela = 600
heightTabela = 500
def zatvaranje():
    popup.destroy()

screenw = popup.winfo_screenwidth()
screenh = popup.winfo_screenheight()
x = screenw / 2 - widthTabela / 2
y = screenh / 2 - heightTabela / 2
popup.geometry("%dx%d+%d+%d" % (widthTabela, heightTabela, x, y))


textTFrame = Frame(popup, borderwidth=1, relief="sunken")
textTabela = Text(textTFrame, width=83, height=28.4, wrap="none", borderwidth=0)
textTVSB = Scrollbar(textTFrame, orient="vertical", command=textTabela.yview)
textTHSB = Scrollbar(textTFrame, orient="horizontal", command=textTabela.xview)
textTabela.configure(yscrollcommand=textTVSB.set, xscrollcommand=textTHSB.set, font=("Arial", 10))
textTabela.config(state="disabled")
textTabela.grid(row=0, column=0, sticky="nsew")
textTVSB.grid(row=0, column=1, sticky="ns")
textTHSB.grid(row=1, column=0, sticky="ew")
textTFrame.grid(row=0, column=0)

file=open("D:\\Pycharm_Skripte\\IEEE9.txt","r")

listaPodataka = file.readlines()
textTabela.config(state="normal")
textTabela.delete('1.0', END)
for i in range(len(listaPodataka)):
    print(listaPodataka[i])
    textTabela.insert(INSERT, listaPodataka[i])
textTabela.config(state="disabled")

dugmeTabela=Button(popup, text="Close", command=zatvaranje).grid(row=2, column=0)
popup.mainloop()

Current result:

Question : Print tabular formated text into a tk.Text widget, not aligned as its supposed.
In the console, its aligned correctly.

You have to use a fixed-width font, eg font=('Consolas', 10) .

• A monospaced font, also called a fixed-pitch, fixed-width, or non-proportional font

Reference:

• Tkinter.Text.config-method
• Dialog Windows
• tabulate output, displayed in a tk.Label , without to distort the data.
• text-alignment-issue-in-listbox

This example shows the usage in a tkinter Dialog :

import tkinter as tk
from tkinter import simpledialog


class TextDialog(simpledialog.Dialog):
    def __init__(self, parent, data):
        self.data = data
        # super() returns at `.destroy()`
        super().__init__(parent, "Podaci mreze")

    def deiconify(self):
        width, height = 600, 500
        screenw, screenh = self.winfo_screenwidth(), self.winfo_screenheight()
        x, y = screenw // 2 - width // 2, screenh // 2 - height // 2
        self.geometry('{width}x{height}+{x}+{y}'.format(width=width, height=height, x=x, y=y))
        super().deiconify()

    def body(self, frame):
        text = tk.Text(frame, font=('Consolas', 10), wrap="none", borderwidth=0)
        text.grid(sticky='ewns')

        text.insert('1.0', self.data)
        return text
