如何使用curses 和Python 设置窗口背景颜色？

Question

我的目标：使窗口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)

我的期望是我的窗口将是蓝色的，并出现“这不是蓝色”。相反，我得到这个窗口：

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

它甚至不是很蓝。

我也尝试过：

• 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

这些以及更多，都无济于事。

那么问题来了：如何在curses中设置窗口的背景颜色？

Answer 1

显然你必须curses.init_pair在使用它们之前指定你的颜色。然后你可以使用它们curses.color_pair：

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)
