Използвам Python 3.3 и tkinter, за да направя GUI интерфейс за симулация на бягащ пешеходец.
Написах две симулационни програми и те работиха добре. Заседнах обаче, когато се опитвах да им се обадя от основното си приложение. Искам прозорецът за симулация да се показва в отделен прозорец (създайте дъщерен прозорец на главния прозорец).

Как мога да стартирам дъщерен прозорец от основното си приложение с tkinter?
