我正在使用Zelle 图形库，但无法替换图形对象（在这种情况下，恰好是文本对象）。
这是代码：
from Graphics import *
winName = "Window"
win = Window(winName,600,500)
win.setBackground(Color('silver'))
title = Text((300,20),"Zack's Flash Card Maker")
title.draw(win)
p1 = Rectangle((50, 100),(550,400))
p1.setFill(Color("black"))
p1.draw(win)
class FlashCard:
def __init__(self):
self.commands = {'addQuestion':self.addQuestion,'startGame':self.startGame}
self.stack = []
self.questions = {}
self.questionAnswered = False
self.questionsCorrect = 0
self.questionsIncorrect = 0
def addQuestion(self):
question = ' '.join(self.stack)
self.stack = []
answer = input(question)
self.questions[question] = answer
def startGame(self):
for question in self.questions:
if(self.questionAnswered == False):
answer=input(question)
questionText = Text((300,150),question)
questionText.setFill(Color("white"))
questionText.draw(win)
if(answer == self.questions[question]):
questionAnswer = Text((300,200),answer + " is correct!")
questionAnswer.setFill(Color("green"))
questionAnswer.draw(win)
self.questionsCorrect = self.questionsCorrect + 1
continue
else:
questionAnswer = Text((300,200),answer + " is incorrect. Study this one.")
questionAnswer.setFill(Color("red"))
questionAnswer.draw(win)
self.questionsIncorrect = self.questionsIncorrect + 1
continue
def interpret(self,expression):
for token in expression.split():
if token in self.commands:
operator = self.commands[token]
operator()
else:
self.stack.append(token)
i = FlashCard()
i.interpret('What is your dog\'s name? addQuestion')
i.interpret('What is your favorite thing to do? addQuestion')
i.interpret('startGame')
这本质上是我正在制作的迷你闪存卡程序。它采用底部的解释命令并根据 FlashCard 类中的字典执行它们。它基本上可以工作：它执行正确的文本对象。但是，由于重新绘制，文本开始与其他文本对象重叠。我尝试过移动 .draw 函数，但它要么根本不出现，要么重叠。
有人有什么建议吗？我希望为每个新的抽认卡问题替换文本。
谢谢！
