PySimpleGUI-更新列表项

问题描述

我正在尝试在GUI中进行简单的琐事测验，但似乎无法更新窗口，以便继续进行下一个问题。我已经尝试了一段时间，我想出的任何解决方案都可以部分起作用或使窗口崩溃！想知道是否有人可以告诉我如何更新当前窗口以显示以下问题？

class Question:
    def __init__(self,prompt,answer):
        self.prompt = prompt
        self.answer = answer

questions = [
    Question(multiple_choice[0],"D"),Question(multiple_choice[1],"A"),Question(multiple_choice[2],"B"),Question(multiple_choice[3],"C"),Question(multiple_choice[4],Question(multiple_choice[5],Question(multiple_choice[6],Question(multiple_choice[7],Question(multiple_choice[8],Question(multiple_choice[9],Question(multiple_choice[10],Question(multiple_choice[11],Question(multiple_choice[12],Question(multiple_choice[13],Question(multiple_choice[14],Question(multiple_choice[15],Question(multiple_choice[16],Question(multiple_choice[17],Question(multiple_choice[18],Question(multiple_choice[19],"D")
]

sg.theme("DarkGreen5")
# All the stuff inside your window. This is the PSG magic code compactor...
layout = [[sg.Text()],[sg.Text(multiple_choice[0])],[sg.Text("Choose your answer:"),sg.input()],[sg.Ok("Submit"),sg.Cancel("End Quiz")]]

# Create the Window
window = sg.Window("Logan's Quiz",layout)

# Event Loop to process "events"
while True:
    event,values = window.read()
    if event in (sg.WIN_CLOSED,'End Quiz'):
        break
    if event == "Submit":
        for question in questions:
            answer = sg.input()
            if answer == question.answer:
                window[multiple_choice[0]].update(multiple_choice[1])
window.close()

这是我目前拥有的！

我省略了这些问题，因为它们对于找出解决方案不是太必要-我不相信！

解决方法

几件事：

• 输入框名称应为通用名称，例如“ question”（问题），因为您将对每个问题使用该框。
• 使用循环遍历问题列表，在每个正确答案后更新文本框
• 通过问题对象而不是使用multiple_choice列表访问问题数据

尝试以下代码：

sg.theme("DarkGreen5")
# All the stuff inside your window. This is the PSG magic code compactor...
layout = [[sg.Text()],[sg.Text("Question")],[sg.Text("Choose your answer:"),sg.Input()],[sg.Ok("Submit"),sg.Cancel("End Quiz")]]

# Create the Window
window = sg.Window("Logan's Quiz",layout)

qcur = 0  # current question 
window['Question'].update(questions[qcur].prompt)  # first question

# Event Loop to process "events"
while True:
    event,values = window.read()
    if event in (sg.WIN_CLOSED,'End Quiz'):
        break
    if event == "Submit":
        answer = sg.Input()
        if answer == questions[qcur].answer:
            qcur += 1  # next question
            if qcur = len(questions): qcur = 0  # restart list
            window['Question'].update(questions[qcur].prompt) # show next question
window.close()
