Кнопка сброса на ткинтер

Question

Я подготовил забавную работу из моего CS-курса для подготовки к A-Level, так как у нас нет никакой «официальной» работы, которую я выполнил, как я закончил 11-й год, задача - игра типа «Mastermind»

Игрок угадывает цвета в порядке, и сколько прав

Я впервые использую Tkinter , я нашел судьбу (), но затем я не могу перезапустить программу, не нажимая снова «run» вручную.

Есть ли способ удалить все виджеты, а затем снова отобразить их. Как кнопка сброса.

вот мой код:

#the main window
win = Tk()
#the main frame
MainFrame = Frame(win)
#the frame which contains the buttons
ButtonFrame = Frame(win)
#will contain the game
MainCanvas = Canvas(MainFrame, height=550)
#the bottom most frame, contains the new game button
BottomFrame = Frame(win)


def closeWin():
    win.destroy()

def updateCoordinates(coodinates,NumberOfPresses):
    for i in range (4):
        print(i)
        if coodinates[i] == coodinates[0]:
                print(coodinates)
                coodinates[i] = coodinates[i] + 60
                print(coodinates)
        elif coodinates[i] == coodinates[1] and NumberOfPresses >= 5:
                coodinates[i] = coodinates[i] - 60
                print(coodinates)
        elif coodinates[i] == coodinates[2]:
                coodinates[i] = coodinates[i] + 60
                print(coodinates)
        elif coodinates[i] == coodinates[3] and NumberOfPresses >= 5:
                coodinates[i] = coodinates[i] - 60
                print(coodinates)
    return coodinates

#this is run is the red button is pressed
def redGuess(coodinates,NumberOfPresses):
    redGuess = MainCanvas.create_oval(coodinates, fill="red")
    NumberOfPresses = NumberOfPresses + 1
    updateCoordinates(coodinates,NumberOfPresses)
    return NumberOfPresses, coodinates

def blueGuess(coodinates,NumberOfPresses):
    blueGuess = MainCanvas.create_oval(coodinates, fill="blue")
    NumberOfPresses = NumberOfPresses + 1
    updateCoordinates(coodinates,NumberOfPresses)
    return NumberOfPresses, coodinates

def MakeAnswer():
    #the list of the colours
    colours = list("rbygwo")
    #randomizes them
    random.shuffle(colours)
    #creates a new list of the randomised letters
    order = ''.join(colours)
    result = ''
    for i in (order):
        #loops through each letter and adds a space bettween them
        result = result + i + ' '
    #calls the new list answer AND puts each letter into a sepearte index in a list
    answer = result.split()
    #removes one colour from the answer
    answer.pop(5)
    return answer


#runs the main program
def NewGame():
    NumberOfPresses = 0
    coodinates = [15,500,65,550]
    answer = MakeAnswer()
    redButton = Button(ButtonFrame,height=3, width=7 ,bg= "red", command =lambda: redGuess(coodinates,NumberOfPresses))
    blueButton = Button(ButtonFrame,height=3, width=7 ,bg= "blue", command =lambda: blueGuess(coodinates, NumberOfPresses))
    yellowButton = Button(ButtonFrame,height=3, width=7 ,bg= "yellow")
    greenButton = Button(ButtonFrame,height=3, width=7 ,bg= "green")
    whiteButton = Button(ButtonFrame,height=3, width=7 ,bg= "white")
    orangeButton = Button(ButtonFrame,height=3, width=7 ,bg= "orange")
    #displays all the widgets in the window
    MainFrame.pack()
    ButtonFrame.pack()
    MainCanvas.pack()
    BottomFrame.pack(side=BOTTOM)
    redButton.pack(side=LEFT, fill=X)
    blueButton.pack(side=LEFT, fill=X)
    yellowButton.pack(side=LEFT, fill=X)
    greenButton.pack(side=LEFT, fill=X)
    whiteButton.pack(side=LEFT, fill=X)
    orangeButton.pack(side=LEFT, fill=X)
    reset_button = Button(BottomFrame, text="Start A New Game", command = closeWin)
    reset_button.pack(side=BOTTOM, fill=X)
    #displayes the correct sequence
    print(answer)
    return

#starting coodinates of the first guess
#format= [x1, y1, x2, y2]


#Start of the game
NewGame()

#creates the buttons to select the different colours

#runs the game continuously
win.mainloop()

также просто для того, чтобы вы знали, что счетчик нажатий кнопок не работает должным образом, но я не могу это исправить, пока не смогу сбросить окно.

Answer 1

Вы можете использовать функцию .withdraw().

.destroy() буквально уничтожает виджет, и вы не сможете вернуть его, как только уничтожите. Если вы обратитесь к нему после его уничтожения, вы получите ошибку.

Итак, вам нужно будет использовать .withdraw(), чтобы сделать его временно исчезающим, а чтобы вернуть его, вы должны использовать .deiconify().

Вот пример:

from tkinter import *
window = Tk()
window2 = Toplevel()
def go_away():
    window.withdraw()
def come_back():
    window.deiconify()
b = Button(window, text = "go away", command = go_away).pack()
b2 = Button(window2, text = "come back", command = come_back).pack()
window.mainloop()

Надеюсь, этот ответ поможет!

Answer 2

Нет, нет функции с именем reset, которая делает то, что вы хотите. Вам нужно создать ее вручную. В вашем коде reset означает:

1. создать новую переменную answer
2. удалить все объекты на холсте.
3. инициализировать вашу переменную set.

Таким образом, весь код может быть:

from tkinter import *
import random
win = Tk()
#the main frame
MainFrame = Frame(win)
#the frame which contains the buttons
ButtonFrame = Frame(win)
#will contain the game
MainCanvas = Canvas(MainFrame, height=550)
#the bottom most frame, contains the new game button
BottomFrame = Frame(win)

def updateCoordinates(coodinates,NumberOfPresses):
    for i in range (4):
        print(i)
        if coodinates[i] == coodinates[0]:
                print(coodinates)
                coodinates[i] = coodinates[i] + 60
                print(coodinates)
        elif coodinates[i] == coodinates[1] and NumberOfPresses >= 5:
                coodinates[i] = coodinates[i] - 60
                print(coodinates)
        elif coodinates[i] == coodinates[2]:
                coodinates[i] = coodinates[i] + 60
                print(coodinates)
        elif coodinates[i] == coodinates[3] and NumberOfPresses >= 5:
                coodinates[i] = coodinates[i] - 60
                print(coodinates)
    return coodinates

#this is run is the red button is pressed
def redGuess(coodinates,NumberOfPresses):
    redGuess = MainCanvas.create_oval(coodinates, fill="red")
    NumberOfPresses = NumberOfPresses + 1
    updateCoordinates(coodinates,NumberOfPresses)
    return NumberOfPresses, coodinates

def blueGuess(coodinates,NumberOfPresses):
    blueGuess = MainCanvas.create_oval(coodinates, fill="blue")
    NumberOfPresses = NumberOfPresses + 1
    updateCoordinates(coodinates,NumberOfPresses)
    return NumberOfPresses, coodinates
