Question: A Button that activate / deactivate the entry in the same Row

Define your own widget which combines tk.Button and tk.Entry in a own tk.Frame.
The Entry state get toggeld on every click on the Button.

Relevant - extend a tkinter widget using inheritance.

import tkinter as tk


class ButtonEntry(tk.Frame):
    def __init__(self, parent, **kwargs):
        super().__init__(parent, **kwargs)

        self.button = tk.Button(self, text='\u2327', width=1, command=self.on_clicked)
        self.button.grid(row=0, column=0)

        self.entry = tk.Entry(self)
        self.columnconfigure(1, weight=1)
        self.entry.grid(row=0, column=1, sticky='ew')

    def on_clicked(self):
        b = not self.entry['state'] == 'normal'
        state, text = {True: ('normal', '\u2327'), False: ('disabled', '\u221A')}.get(b)
        self.entry.configure(state=state)
        self.button.configure(text=text)

Usage:

class App(tk.Tk):
    def __init__(self):
        super().__init__()

        for row in range(5):
            ButtonEntry(self).grid(row=row, column=1)


if __name__ == '__main__':
    App().mainloop()
