Question

我正在尝试使用python随附的curses模块编写一个简单的CLI python文本编辑器。我已经在Windows 10机器上正确设置了所有内容，并且可以顺利完成所有教程。

我按顺序绘制屏幕，屏幕和屏幕上边框小于屏幕的窗口。使用从屏幕外部开始的两行，两列的边界测量值创建一个窗口。然后定义一个文本区域并创建一个子窗口。

如果我排除子窗口，则会绘制一个边框并将光标放置在边框内。但是，当我尝试通过收集文本来保存文本时，文本会包含边框。因此，这就是创建子窗口的原因。如果他的框大于子窗口，为什么边框会消失。

代码如下：

import curses
import traceback

from curses.textpad import Textbox, rectangle
from pathlib import Path


def draw_menu():
    pass

def edit_mode(window):
    textbox = Textbox(window)
    textbox.edit()

    return textbox.gather()

def main(screen):
    """
    Get the screen size and set a border around the text area.
    Reset the cursor to the top of the text area.
    """

    # get the current screen size
    y_max, x_max = screen.getmaxyx()
    ymin_border, xmin_border, ymax_border, xmax_border = \
        2, 2, y_max-2, x_max-2
    ymin_textpad, xmin_textpad, ymax_textpad, xmax_textpad = \
        ymin_border+1, xmin_border+1, ymax_border-1, xmax_border-1

    # draw the windows and box around it. Place cursor at beginning of 
    # the edit area
    window = curses.newwin(ymax_border, xmax_border, ymin_border, xmin_border)
    window.box()

    # if this line is excluded I see the box but then the box is saved input
    text_box = screen.subwin(ymax_textpad, xmax_textpad, ymin_textpad, 
                             xmin_textpad)
    window.addstr(ymin_textpad, xmin_textpad, "")
    screen.refresh()

    text = edit_mode(text_box) # right now drop user into edit mode

    return text


if __name__ == "__main__":
    buffer = ""
    try:
        screen = curses.initscr()
        curses.noecho()
        buffer = main(screen)
        curses.echo()
        curses.endwin()
        print(f"Saved Buffer to Screen\n{buffer}")
    except:
        curses.echo()
        curses.endwin()
        traceback.print_exc()
