Tkinter具有相同圖像的圖像標籤除最後一個外不可見

Question

我遇到的問題是相同的圖像（標籤中）除最後一個標籤外不會顯示。這是一張照片，向你展示我的意思。在這張圖片中，我生成了7張卡片，然後生成了2.我希望空白處填充問號。

可以創建的最大卡數範圍爲0-8。如果我生成6張卡片然後生成4張卡片，我希望卡片5-6重新回到隨機卡片圖像。

卡類

import tkinter as tk 
from PIL import Image, ImageTk 
class Card: 
    def __init__(self, name, imageURL, cardType, rarity): 
     self.name = name 
     self.imageURL = imageURL 
     self.cardType = cardType 
     self.rarity = rarity 
    def __repr__(self): 
     print(self.name) 
    def __str__(self): 
     return self.name 
    def returnImage(self): 
     self.timage = Image.open(self.imageURL) 
     if not self.timage.size == (212,263): 
      self.timage = self.timage.resize((212,263), Image.ANTIALIAS) 
     self.tphoto = ImageTk.PhotoImage(self.timage) 
     return self.tphoto 
    def createLabel(self, parent): 
     self.timage = Image.open(self.imageURL) 
     if not self.timage.size == (212,263): 
      self.timage = self.timage.resize((212,263), Image.ANTIALIAS) 
     self.tphoto = ImageTk.PhotoImage(self.timage) 
     self.cardLabel = tk.Label(parent, image = self.tphoto) 
     self.cardLabel.image = self.tphoto 
     return self.cardLabel 

主要

randomUnknown = Card("RANDOM", PATH + '\\random-unknown.png', 'N/A', 'N/A') 
#Note: randomUnknown is in a separate file. The card.randomUnknown just calls it 
randomCard = card.randomUnknown 

card1 = randomCard 
card2 = randomCard 
card3 = randomCard 
card4 = randomCard 
card5 = randomCard 
card6 = randomCard 
card7 = randomCard 
card8 = randomCard 

card1Label = card1.createLabel(root) 
card2Label = card2.createLabel(root) 
card3Label = card3.createLabel(root) 
card4Label = card4.createLabel(root) 
card5Label = card5.createLabel(root) 
card6Label = card6.createLabel(root) 
card7Label = card7.createLabel(root) 
card8Label = card8.createLabel(root) 

這是在我的代碼的頂部創建窗口後。每個標籤都與我想要顯示的圖像正確顯示。像這樣在這裏：

MY未遂

每個按鈕被按下時，卡被採摘並顯示。此代碼也運行。我也嘗試將標籤設置爲randomCard.createLabel（root），但同樣的事情發生了。

def randomizeButton(): 
    global currentCards,card1Label, card2Label,card3Label,card4Label,card5Label,card6Label,card7Label,card8Label 
    currentCards = maxCards 
    setMax() 
    randomizeCards() 
    print('Current Cards: ' + str(currentCards)) 
    if(maxCards == 0): 
     card1Label.configure(image = randomCard.returnImage()) 
     card2Label.configure(image = randomCard.returnImage()) 
     card3Label.configure(image = randomCard.returnImage()) 
     card4Label.configure(image = randomCard.returnImage()) 
     card5Label.configure(image = randomCard.returnImage()) 
     card6Label.configure(image = randomCard.returnImage()) 
     card7Label.configure(image = randomCard.returnImage()) 
     card8Label.configure(image = randomCard.returnImage()) 
    if(maxCards == 1): 
     card2Label.configure(image = randomCard.returnImage()) 
     card3Label.configure(image = randomCard.returnImage()) 
     card4Label.configure(image = randomCard.returnImage()) 
     card5Label.configure(image = randomCard.returnImage()) 
     card6Label.configure(image = randomCard.returnImage()) 
     card7Label.configure(image = randomCard.returnImage()) 
     card8Label.configure(image = randomCard.returnImage()) 
    if(maxCards == 2): 
     card3Label.configure(image = randomCard.returnImage()) 
     card4Label.configure(image = randomCard.returnImage()) 
     card5Label.configure(image = randomCard.returnImage()) 
     card6Label.configure(image = randomCard.returnImage()) 
     card7Label.configure(image = randomCard.returnImage()) 
     card8Label.configure(image = randomCard.returnImage()) 
    if(maxCards == 3): 
     card4Label.configure(image = randomCard.returnImage()) 
     card5Label.configure(image = randomCard.returnImage()) 
     card6Label.configure(image = randomCard.returnImage()) 
     card7Label.configure(image = randomCard.returnImage()) 
     card8Label.configure(image = randomCard.returnImage()) 
    if(maxCards == 4): 
     card5Label.configure(image = randomCard.returnImage()) 
     card6Label.configure(image = randomCard.returnImage()) 
     card7Label.configure(image = randomCard.returnImage()) 
     card8Label.configure(image = randomCard.returnImage()) 
    if(maxCards == 5): 
     card6Label.configure(image = randomCard.returnImage()) 
     card7Label.configure(image = randomCard.returnImage()) 
     card8Label.configure(image = randomCard.returnImage()) 
    if(maxCards == 6): 
     card7Label.configure(image = randomCard.returnImage()) 
     card8Label.configure(image = randomCard.returnImage()) 
    if(maxCards == 7): 
     card8Label.configure(image = randomCard.returnImage()) 

標籤設置在網格中。

card1Label.grid(row = 0, column = 0) 
card2Label.grid(row = 0, column = 1) 
card3Label.grid(row = 0, column = 2) 
card4Label.grid(row = 0, column = 3) 
card5Label.grid(row = 1, column = 0) 
card6Label.grid(row = 1, column = 1) 
card7Label.grid(row = 1, column = 2) 
card8Label.grid(row = 1, column = 3) 

如果您需要了解更多信息，我會很樂意提供。我試圖提供所有必要的信息。

Tkinter只允許每個圖像實例使用一次。要多次顯示相同的圖像，您需要爲每個標籤單獨加載圖像。

例如，如果你想顯示相同的圖像5次，你將需要運行像這樣的代碼：

import tkinter 
root = tkinter.Tk() 
image1 = tkinter.PhotoImage(file=icon.gif) 
label1 = tkinter.Label(root, image=image1) 
label1.pack() 
image2 = tkinter.PhotoImage(file=icon.gif) 
label2 = tkinter.Label(root, image=image2) 
label2.pack() 
image3 = tkinter.PhotoImage(file=icon.gif) 
label3 = tkinter.Label(root, image=image3) 
label3.pack() 
image4 = tkinter.PhotoImage(file=icon.gif) 
label4 = tkinter.Label(root, image=image4) 
label4.pack() 
image5 = tkinter.PhotoImage(file=icon.gif) 
label5 = tkinter.Label(root, image=image5) 
label5.pack() 

顯然，這只是一個例子，不使用變量代碼中的名稱或類。
