PySimpleGUI:在多行小工具中设置和获取光标位置？

import PySimpleGUI as sg

layout = [
    [sg.Multiline(default_text='Hello World', key='-TEXT-', size=(30, 10))],
    [sg.Button('Set Cursor'), sg.Button('Get Cursor')]
]

window = sg.Window('Cursor Position Demo', layout)

while True:
    event, values = window.read()
    if event == sg.WINDOW_CLOSED:
        break
    elif event == 'Set Cursor':
        # 设置光标位置为第3行第5列
        window['-TEXT-'].set_cursor((2, 4))
    elif event == 'Get Cursor':
        # 获取当前光标位置
        cursor_pos = window['-TEXT-'].get_cursor()
        sg.popup(f"Cursor Position: {cursor_pos}")

window.close()
