[英]python curses textbox widget
#! /usr/bin/python
import curses
import curses.textpad as textpad
try:
mainwindow = curses.initscr()
textpad.Textbox(mainwindow).edit()
finally:
curses.endwin()
the problem is that I type one character,but two characters display on screen. 问题是我键入了一个字符,但屏幕上却显示了两个字符。
Echoing is on by default. 默认情况下,回显处于打开状态。 You need to call
noecho
for deactivating it. 您需要致电
noecho
使其停用。
#!/usr/bin/env python
import curses
import curses.textpad as textpad
try:
mainwindow = curses.initscr()
# Some curses-friendly terminal settings
curses.cbreak(); mainwindow.keypad(1); curses.noecho()
textpad.Textbox(mainwindow).edit()
finally:
# Reverse curses-friendly terminal settings
curses.nocbreak(); mainwindow.keypad(0); curses.echo()
curses.endwin()
(the script has been tested on Python 2.7). (该脚本已在Python 2.7上进行了测试)。 I suggest you to have a look to the curses programming page .
我建议您看一下curses编程页面 。
