第一：实现上下键捕捉
#handle key up,down, right, left
if input_val == curses.KEY_DOWN:
cursor_y = cursor_y + 1
elif input_val == curses.KEY_UP:
cursor_y = cursor_y - 1
elif input_val == curses.KEY_RIGHT:
cursor_x = cursor_x + 1
elif input_val == curses.KEY_LEFT:
cursor_x = cursor_x - 1
height, width = screen.getmaxyx()
cursor_x = max(0, cursor_x)
cursor_x = min(width - 1, cursor_x)
cursor_y = max(0, cursor_y)
cursor_y = min(height - 1, cursor_y)
第二：移动到某一列制造选中效果
#制造选中效果
if cursor_y == 4:
screen.addstr(4, 4, "1 - 集群配置", curses.A_STANDOUT)
elif cursor_y == 5:
screen.addstr(5, 4, "2 - 资源信息", curses.A_STANDOUT)
elif cursor_y == 6:
screen.addstr(6, 4, "3 - 数据库信息", curses.A_STANDOUT)
elif cursor_y == 7:
screen.addstr(7, 4, "4 - 安装概要", curses.A_STANDOUT)
elif cursor_y == 8:
screen.addstr(8, 4, "5 - 退出", curses.A_STANDOUT)
else:
screen.addstr(4, 4, "1 - 集群配置", curses.A_STANDOUT)
#制造选中效果结束
screen.refresh()
实现效果图如下：
完整可运行代码如下：
