我正在使用fedora 20并通过学习示例程序来学习ncurses编程。我已经在NCURSES Programming HOWTO中找到了一个(在我的文件“border.c”下面列出,请参阅注释),按下功能键F1时应退出:相反,它给了我一个标题为“终端帮助”的窗口,所以我使用CTRL -C退出。我正在使用以下命令从bash shell命令窗口编译和运行程序:
[Harry@localhost ~]$ gcc -o border.o border.c -l ncurses
[Harry@localhost ~]$ ./border.o
拜托,我可以以某种方式覆盖这个F1动作,以便ncurses程序读取并按下按键操作,并且最好还在其他地方保留其默认动作吗?
注意TAB的效果在草稿中是可以的,但实际问题中显示的有点乱。

答案 0 :(得分:0)
类似的问题确实发布在Stackoverflow中,答案是它在系统的各个方面之间不兼容,这看起来很难克服:所以,我现在将避免使用这些笨拙的F键。
经过实验,我现在发现F(2)到F(9)和F(12)工作正常; F(10)打开工具栏;和F(11)打开和关闭全屏;除了我询问的F(1)的影响。
感谢edvinas指出我应该使用Stackoverflow,以及那些迁移它的人
我会尽快接受这个答案,以便在此处保存更多评论
