python - 诅咒中的多个文本框

Question

我需要在 curses 中创建两个文本框，并在按 Enter 时在它们之间切换

当我为第二个文本框按下回车键时，这段代码将光标放在屏幕的左上角，但我无法阻止它。

import curses
import curses.textpad as textpad

def main(screen):
    """screen is a curses screen passed from the wrapper"""

    while True:
        event = screen.getch() 
        if event :
            textpad.Textbox(curses.newwin(1,13,4,0), insert_mode=True).edit()
            textpad.Textbox(curses.newwin(1,13,4,16), insert_mode=True).edit()
            screen.refresh()      

if __name__ == '__main__':     
    curses.wrapper(main)

看起来你甚至不需要调用 getch() 因为这就足够了:

import curses
import curses.textpad as textpad

def main(screen):
    """screen is a curses screen passed from the wrapper"""
    while True:
        textpad.Textbox(curses.newwin(1,13,4,0), insert_mode=True).edit()
        textpad.Textbox(curses.newwin(1,13,4,16), insert_mode=True).edit()

if __name__ == '__main__':   
    curses.wrapper(main)
