PySimpleGui 正在从另一个 Window 更新主 window 元素

Question

嗨，python 的新手，正在做一个学校项目 Screenshot

我目前有一个中学 window 可以登记个别科目的成绩。

点击提交按钮后，我应该在事件循环中添加什么，以便它将主window（右table）上的科目分数更新到已注册的各个学生来自中学 window?

import PySimpleGUI as sg

nameDict = {'A1': 'Albedo',
            'A2': 'Barbara',
            'A3': 'Chongyun',
            'A4': 'Diluc',
            'A5': 'Eula',
            'A6': 'Fischl',
            'A7': 'Ganyu',
            'A8': 'Hu Tao',
            'A9': 'Jean',
            'A10': 'Kazuha'}

nameList = [[1, nameDict["A1"], 3.5],
            [2, nameDict["A2"], 3.5],
            [3, nameDict["A3"], 3.5],
            [4, nameDict["A4"], 3.5],
            [5, nameDict["A5"], 3.5],
            [6, nameDict["A6"], 3.5],
            [7, nameDict["A7"], 3.5],
            [8, nameDict["A8"], 3.5],
            [9, nameDict["A9"], 3.5],

在这里，使用参数调用函数来创建一个新的弹出窗口window。关闭此弹出窗口后 window，return 您需要在主 window 中进行更新的值。

import PySimpleGUI as sg

def popup(name):
    sg.theme('DarkBlue3')
    layout = [
        [sg.Text(f'Score for {name}')]] + [
        [sg.Text(subject, expand_x=True),
         sg.Input('', size=16, key=subject)] for subject in subjects] + [
        [sg.Button('Submit'), sg.Button('Cancel')]]
    event, values = sg.Window('Sub Win', layout, modal=True).read(close=True)
    return None if event == sg.WIN_CLOSED else {subject:values[subject] for subject in subjects}

students = ['Albedo', 'Barbara', 'Chongyun', 'Diluc', 'Eula', 'Fischl', 'Ganyu', 'Hu Tao', 'Jean', 'Kazuha']
subjects = ["English", "Math", 'Science', "Chinese"]
scores = {}

font = ('Courier New', 16)
sg.theme('DarkBlue4')
sg.set_options(font=font)

layout = [
    [sg.Text('Student'),
     sg.Combo(students, size=(10, 5), enable_events=True, bind_return_key=True, key='Student'),
     sg.Button('Update')]] + [
    [sg.Text(subject, expand_x=True),
     sg.Text('None', size=16, background_color='blue', text_color='white', key=subject)] for subject in subjects
]
window = sg.Window('Student Records', layout)

while True:

    event, values = window.read()

    if event == sg.WIN_CLOSED:
        break

    student = values['Student']
    print(event)
    if event in ('Student', 'New Record'):
        if student in scores:
            record = scores[student]
            for subject in subjects:
                window[subject].update(record[subject])
        else:
            for subject in subjects:
                window[subject].update('None')
    elif event == 'Update':
        if student not in students:
            continue
        result = popup(student)
        if result is not None:
            scores[student] = result
            window.write_event_value('New Record', None)

window.close()
