ткинтер, создание кадров с кнопкой и задержкой

Question

, поэтому я пытаюсь создать несколько кадров с помощью кнопки, но с задержками между ними, поэтому я нажимаю кнопку -> создать кадр1 -> подождать 5 секунд -> создать кадр2 и так далее.Но проблема в том, что когда я нажимаю кнопку, это занимает 5 секунд и отображает кадры одновременно.надеюсь, у кого-то есть идеи, как решить эту проблему.

app = lingo()
app.wm_geometry("1810x1080")
app.resizable(False, False)
app.title("pls work")
app.mainloop()

, поэтому на этот раз я добавил весь код и попытался заменить r1l2t.grid () на r1l2t.after (1000, r1l2t.grid ())но без изменений ....

Answer 1

Как только вы запустили основную петлю Tkinter, графический интерфейс ожидает события (нажатия клавиш, щелчки мыши, ...) и немедленно реагирует на них (визуальные эффекты на нажатой кнопке, ...).Однако, когда вы используете time.sleep(5), вы блокируете этот основной цикл, поэтому графический интерфейс не реагирует на события, а обрабатывает их все по истечении 5 секунд.Кроме того, графический интерфейс не обновляется до замораживания, поэтому ваш первый кадр отображается только в конце.Вы можете принудительно обновить графический интерфейс с помощью метода update_idletasks().

Tkinter предоставляет метод для выполнения команд с задержкой без остановки основного цикла: app.after(delay , function, *args) выполнит function(*args) после заданной задержки (в мс).Ошибка, которую вы сделали, заключается в том, что вы назвали r1l2t.after(1000, r1l2t.grid()) вместо r1l2t.after(1000, r1l2t.grid).Ниже приведен небольшой пример создания двух меток при нажатии кнопки с задержкой 5 с между каждым:

import tkinter as tk

app = tk.Tk()

def display():
    l1 = tk.Label(app, text='First label')
    l2 = tk.Label(app, text='Second label')
    l1.grid()
    app.after(5000, l2.grid)

tk.Button(app, text='Display', command=display).grid()


app.mainloop()
