如何使用 curses 和 Python 设置 window 背景颜色？

Question

我的目标：使 window 背景具有特定的颜色。

我当前的代码：

import curses


def do_it(win):  # Shia LeBeouf!
    win.bkgd(' ', curses.COLOR_BLUE)
    win.addstr(1,1, "This is not blue")
    win.getch()

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

我的期望是我的 window 是蓝色，并出现 "This is not blue"。相反，我得到这个 window:

$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
$This$is$not$blue$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$

它甚至不是很蓝。

我也试过：

win.bkgd(curses.COLOR_BLUE) - 似乎删除了所有空格(?)
win.bkgdset(' ', curses.COLOR_BLUE) - 似乎做同样的事情

这些，还有更多，都无济于事。

那么问题来了：如何在curses中设置window的背景颜色？

Answer 1

显然你必须指定你的颜色，在使用它们之前使用 curses.init_pair。然后你可以将它们与 curses.color_pair:

一起使用

import curses


def do_it(win):  # Shia LeBeouf!
    curses.init_pair(1, curses.COLOR_WHITE, curses.COLOR_BLUE)
    win.bkgd(' ', curses.color_pair(1) | curses.A_BOLD)
    win.addstr(1,1, "This is not blue")
    win.getch()
    win.bkgd(' ', curses.color_pair(1) | curses.A_BOLD | curses.A_REVERSE)
    win.addstr(1,1, "This is now blue")
    win.getch()

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