我正在用tkinter制作测验应用程序，我希望每个问题都出现在新窗口中，但是在创建新窗口后，我不知道如何销毁上一个窗口。这是我的代码的简化摘要：
from tkinter import *
class q1:
def __init__(self, master):
self.master = master
Label(self.master, text='What is 3 + 3?').grid()
self.option_1 = Button(self.master, text='5', command = self.incorrect)
self.option_1.grid()
self.option_2 = Button(self.master, text='6', command = self.correct)
self.option_2.grid()
def correct(self):
self.option_1.config(state=DISABLED)
self.option_2.config(state=DISABLED)
Label(self.master, text='Correct').grid()
Button(self.master, text='Next Question', command = self.nextq).grid()
def incorrect(self):
self.option_1.config(state=DISABLED)
self.option_2.config(state=DISABLED)
Label(self.master, text='Incorrect').grid()
Button(self.master, text='Next Question', command = self.nextq).grid()
def nextq(self):
q2(Toplevel(self.master))
class q2:
def __init__(self, master):
self.master = master
Label(self.master, text='Question 2').grid()
def window():
root = Tk()
q1(root)
root.mainloop()
if __name__ == '__main__':
window()
更新后的版本
from Tkinter import *
import random
class Ask:
def __init__(self, parent,question,right,wrong):
self.answer=right
self.top=top=Toplevel(parent)
Label(self.top, text=question,width=25).grid()
a1=random.choice([right,wrong])
self.option_1 = Button(self.top, text=a1, width=25,command = lambda: self.check(1))
self.option_1.grid()
a2=right
if a1==right:
a2=wrong
self.option_2 = Button(self.top, text=a2, width=25, command = lambda: self.check(2))
self.option_2.grid()
def check(self,pressed):
if pressed==1:
ans=self.option_1['text']
else:
ans=self.option_2['text']
if ans==self.answer:
self.correct()
else:
self.incorrect()
def correct(self):
self.option_1.config(state=DISABLED)
self.option_2.config(state=DISABLED)
Label(self.top, text='Correct').grid()
Button(self.top, text='Next Question', command = self.top.destroy).grid()
def incorrect(self):
self.option_1.config(state=DISABLED)
self.option_2.config(state=DISABLED)
Label(self.top, text='Incorrect').grid()
Button(self.top, text='Next Question', command = self.top.destroy).grid()
class QUIZ:
def __init__(self, questionsdict):
self.root=Tk()
self.root.withdraw()
self.questions(questionsdict)
self.root.deiconify()
c=Button(self.root, text='Click me to exit', command=self.root.destroy, width=30).grid(row=2, sticky='ew')
Label(self.root, text='Quiz is Complete', width=30, background='red').grid(row=0, sticky='ew')
mainloop()
def questions(self,questionsdict):
for k in questionsdict.keys():
right=questionsdict[k][0]
wrong=questionsdict[k][1]
b=Ask(self.root, k, right,wrong )
self.root.wait_window(b.top)
以{question：[correctchoice，incorrectchoice]}格式将测验问题放入字典中，并在调用Question Class时将其用作参数
questions={'What is 3+3':['6','8'], 'What is the capital of Alaska': ['Juno','Anchorage']}
QUIZ(questions)
