Cerrar una ventana Tk en proceso

Hola Phil,

No sé si eso cubrirá tus necesidades, pero con el método update() y un binding en la cruz de la ventana, vería algo así:

import tkinter as tk
flag = True

def loop():
    i = 0
    while flag:
        i += 1
        print(f"Loop n° {i}")
        root.update()
    print("Loop off")

def on_exit():
    global flag
    flag = False
    root.destroy()

root = tk.Tk()
but_search = tk.Button(root, text="Search", command=loop)
but_search.pack()
but_quit = tk.Button(root, text="Quit", command=on_exit)
but_quit.pack()
root.protocol('WM_DELETE_WINDOW', on_exit)
root.mainloop()

hola,

¿esto da un mensaje de error cuando cierras la ventana?

import tkinter
raíz = tkinter.Tk()
etiqueta = tkinter.Label(raíz, text="¡Me encanta Python!")
etiqueta.pack()
raíz.mainloop()
print("terminado")

Hi.

Indeed, tkinter or any GUI won’t be able to close if we don’t hand control back to it.

So, the solution isn’t in tkinter but in your search method, which seems to be blocking. Roughly, how is it performed?

Couldn't you put that in a thread?

In a very rough summary:

import tkinter import threading class Search(threading.Thread): def __init__(self, text): super().__init__() self._text = text self._stopped = threading.Event() def run(self): # simulation de qqchose qui prend du temps import time while not self._stopped.is_set(): self._text.insert(tkinter.END, f'{round(time.time())}\n') time.sleep(2) def stop(self): self._stopped.set() def wait_done(ms, window, search): if search.is_alive(): print('waiting...') window.after(ms, wait_done, ms, window, search) else: window.destroy() def on_close(window, search): search.stop() wait_done(100, window, search) def search_run(search, text, button): button.destroy() search.start() window = tkinter.Tk() text = tkinter.Text(window) text.grid() search = Search(text) button = tkinter.Button(window, text='rechercher') button.grid() button.configure(command=lambda: search_run(search, text, button)) window.protocol('WM_DELETE_WINDOW', lambda: on_close(window, search)) window.mainloop()

?

Hola yg_be,

Así es: hice la prueba antes de leer tu respuesta, pero después de leer

la de las 11:52

Funciona muy bien

Gracias de nuevo a todos, ¡problema resuelto!

Creo que también se puede optimizar el código creando un diccionario a partir de la lista de palabras, tomando como clave la longitud, y creando ana_set a medida que se itera para controlar los boúblons:

import itertools as it from tkinter import * def show_result(evt): t1.delete(0.0, END) it_perm = it.permutations(e1.get()) anag_set = set() for perm in it_perm: word = "".join(perm) if not len(word) in dico.keys(): break if word in dico[len(word)] and word not in anag_set: t1.insert(END, word+"\n") anag_set.add(word) if not anag_set: t1.insert(END, 'Rien') def on_exit(): main_win.destroy() WIDTH, HEIGHT = 320, 200 dico = {} with open('dico.txt', 'r') as f: for line in f: line = line.strip() longueur_mot = len(line) if longueur_mot not in dico: dico[longueur_mot] = [line] else: dico[longueur_mot].append(line) main_win = Tk() main_win.title('Décoder una anagrama') main_win.geometry(f"{WIDTH}x{HEIGHT}+400+100") main_win.protocol('WM_DELETE_WINDOW', on_exit) l1 = Label(main_win, text='Anagramme :') l1.place(x=10, y=20) e1 = Entry(main_win, width=10) e1.place(x=100, y=20) e1.bind("<Return>", show_result) e1.focus() t1 = Text(main_win, width=30, height=7) t1.place(x=10, y=50) main_win.mainloop() 

je pense que ça peut être encore optimiser

J'ai fini par faire ceci, et ça marche pas mal:
