[Tkinter] How to get the result of a ping to show in tkinter?

[Yoriz]

This is quite a tricky task as calling ping can block the GUI mainloop.
The code below uses the technique from the following forum tutorial.

import functools
import os
import tkinter as tk
from concurrent import futures

thread_pool_executor = futures.ThreadPoolExecutor(max_workers=1)


def tk_after(target):

    @functools.wraps(target)
    def wrapper(self, *args, **kwargs):
        args = (self,) + args
        self.after(0, target, *args, **kwargs)

    return wrapper


def submit_to_pool_executor(executor):

    def decorator(target):

        @functools.wraps(target)
        def wrapper(*args, **kwargs):
            return executor.submit(target, *args, **kwargs)

        return wrapper

    return decorator


class MainFrame(tk.Frame):

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.master.geometry('500x350')
        self.master.title("Get output inside GUI")
        self.entry = tk.StringVar()
        label = tk.Label(
            self.master, text="Enter target IP or host as required.")
        label.pack()
        entry = tk.Entry(self.master, textvariable=self.entry)
        entry.insert(-1, "8.8.8.8")
        entry.pack()
        self.button = tk.Button(
            self.master, text="Ping Test", command=self.on_button)
        self.button.pack()
        self.text = tk.Text(self.master)
        self.text.config(state=tk.DISABLED)
        self.text.pack(padx=5, pady=5)

    @tk_after
    def button_state(self, enabled=True):

    @tk_after
    def insert_text(self, text):
        self.text.config(state=tk.NORMAL)
        self.text.insert(tk.END, text)
        self.text.config(state=tk.DISABLED)

    def on_button(self):
        self.ping()

    @submit_to_pool_executor(thread_pool_executor)
    def ping(self):
        self.button_state(False)
        self.clear_text()
        self.insert_text('Starting ping request')

        result = os.popen("ping "+self.entry.get()+" -n 2")
        for line in result:
            self.insert_text(line)

        self.insert_text('ping request finished')
        self.button_state(True)
