Ncurses有限的输出大小 [英] Ncurses limited output size

问题描述

我正在学习如何使用ncurses，我在一个奇怪的情况。
看来我的输出不能超过24行。
此外，每当我运行我的软件，并且执行完成他的工作，我的终端停止工作，以前，我有两种不同的情况：

I'm learning how to use ncurses and I'm in a weird situation. It seems my output can't go over 24 lines. Moreover, whenever I run my software, and the execution finishes his job, my terminal stops working as before, and I have 2 different situations:

• 如果我从第24行后面的行启动了我的运行，我可以使用终端，但如果我在窗口的最后一行继续滚动，没有什么更多发生：所有输入和输出继续发生在


• 如果我已经启动第24行以上的运行，终端只会变为24行高。

这两种情况都要求我重置终端，然后一切正常。
我在MAC OSX机器上。

Both situations require me to reset the terminal, then everything works again. I'm on MAC OSX machine.

推荐答案

屏幕尺寸有问题：

• 最容易看到的是如果您将 LINES 环境变量设置为24. < a href =http://invisible-island.net/ncurses/man/curs_util.3x.html =nofollow> use_env 联机帮助页


• 屏幕尺寸问题的原因是，问题的描述表明程序将滚动区域设置为24行。


• 如果 LINES 没有问题，那么要检查的地方是运行 stty -a 看看操作系统假设屏幕大小是什么。在 stty 的第一行报告为rows。


• 在某些情况下连接），则可能有远程主机无法获取屏幕大小的会话。作为解决方法，您可以运行 resize 程序（xterm实用程序）更新操作系统的屏幕大小概念。

• The easiest one to see is if you has LINES environment variable set to 24. The use_env manpage gives some clues about that.
• The reason why it sounds like a problem with screen-size is that the description of the problem suggests that the program is setting the scrolling region to 24 lines.
• If there is no problem with LINES, then a place to check is by running stty -a to see what the operating system supposes the screen-size to be. That is reported on the first line of stty's output as "rows".
• In some cases (for instance in remote network connections), it is possible to have a session where the remote host cannot obtain the screen-size. As a workaround, you could run the resize program (an xterm utility) to update the operating system's notion of the screen-size.

顺便说一句，您的其他问题 NCurses未恢复终端行为似乎与此重复。您应该将您的问题整合到一个单一的问题中，为某人提供足够的信息来提供有关该问题的有用信息。

By the way, your other question NCurses not restoring terminal behavior appears to be a duplicate of this. You should consolidate your questions into a single one which provides enough information for someone to offer useful information about the problem.
