如何获取关闭窗口表单中的数据
--------------------------------------------------

.. code-block:: python

    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()
