ncurses:如何查看鼠标左键或右键的点击情况？

import curses

stdscr = curses.initscr()
curses.cbreak()
curses.noecho()
stdscr.keypad(True)

curses.mousemask(curses.ALL_MOUSE_EVENTS)

while True:
    # 等待用户输入
    key = stdscr.getch()

    # 如果是鼠标事件
    if key == curses.KEY_MOUSE:
        _, x, y, _, button_state = curses.getmouse()

        # 检查鼠标左键或右键的点击情况
        if button_state & curses.BUTTON1_CLICKED:
            # 鼠标左键被点击
            # 处理逻辑
        elif button_state & curses.BUTTON3_CLICKED:
            # 鼠标右键被点击
            # 处理逻辑
