[Tkinter] Have tkinter button toggle on and off a continuously running function

[Yoriz]

Something like this?

import tkinter as tk
from itertools import cycle


class MainFrame(tk.Frame):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, *kwargs)
        self._timer = False
        self._button1_state = cycle(("disabled", "normal"))
        self._create()
        self._layout()
        self._binds()

    def _create(self):
        self.button1 = tk.Button(self, text="Button1")

    def _layout(self):
        self.button1.pack(padx=5, pady=5)

    def _binds(self):
        self.button1.bind("<ButtonRelease-1>", self._on_button1)

    def _on_button1(self, event):
        if not self._timer:
            self.toggle_button1()
        else:
            self.after_cancel(self._timer)
            self.button1.config(state="normal")
            self._timer = None

    def toggle_button1(self):
        self.button1.config(state=next(self._button1_state))
        self._timer = self.after(100, self.toggle_button1)


def main():
    app = tk.Tk()
    mainframe = MainFrame(app)
    mainframe.pack()
    app.mainloop()


if __name__ == "__main__":
    main()
