4.5.8.1. 如何获取关闭窗口表单中的数据

import PySimpleGUI as sg

# 创建窗口1
def create_window1():
    layout = [[sg.Text('Window 1')],
            [sg.Input(key='-INPUT-')],
            [sg.Button('Next')]]
    return sg.Window('Window 1', layout, finalize=True)

# 创建窗口2
def create_window2(data):
    layout = [[sg.Text('Window 2')],
            [sg.Text(f'Input from Window 1: {data}')],
            [sg.Button('Close')]]
    return sg.Window('Window 2', layout, finalize=True)

def main():
    window1 = create_window1()
    window2 = None

    while True:
        window, event, values = sg.read_all_windows()

        # 这里是重点，如果当前窗口是窗口1，并且是关闭事件。则需要从values中获取窗口1中的-INPUT-中的值，再关闭窗口1.
        if window == window1 and event == sg.WINDOW_CLOSED:
            # 获取窗口1的输入值
            input_value = values['-INPUT-']
            window1.close()  # 关闭窗口1

            # 创建窗口2，并传递窗口1的输入值
            window2 = create_window2(input_value)

        if window == window2 and event == sg.WINDOW_CLOSED or event == 'Close':
            window2.close()  # 关闭窗口2
            break

    window.close()

if __name__ == '__main__':
    main()
