有没有一个pysimplegui函数来获取输入光标的位置？

import PySimpleGUI as sg

layout = [
    [sg.Input(key='-INPUT-', enable_events=True)],
    [sg.Text('光标位置: '), sg.Text('', key='-CURSOR-')],
    [sg.Button('获取光标位置')]
]

window = sg.Window('获取光标位置示例', layout)

while True:
    event, values = window.read()
    if event == sg.WINDOW_CLOSED:
        break
    elif event == '获取光标位置':
        cursor_position = window['-INPUT-'].get_input_cursor_position()
        window['-CURSOR-'].update(cursor_position)

window.close()
