ncurses

How to clear a specific line with NCurses? I need to wipe a line on the screen without redrawing the whole thing. How do I do that? You can position on the line you want to clear and then call clrtoeol function. This is how I ended up doing it for my purposes. int y, x; // to store where you are getyx(stdscr, y, x); // save current pos move(y, 0); // move to begining of line clrtoeol(); // clear line move(y, x); // move back to where you were maybe crltoeol would do the trick Scienziatogm If you want to clear all lines from the cursor until the last line, you can call clrtobot() 来源： https:/

I'm attempting to add wchar_t Unicode characters to an ncurses display in C. I have an array: wchar_t characters[]={L'\uE030', L'\uE029'}; // containing 2 thai letters, for example And I later try to add a wchar_t from the array to the ncurses display with: add_wch(characters[0]); To provide a bit more info, doing this with ASCII works ok, using: char characters[]={'A', 'B'}; // and later... addch(characters[0]); To setup the locale, I add the include... #include <locale.h> // in main() setlocale(LC_CTYPE,"C-UTF-8"); The ncurses include is: #include <ncurses.h> Compiling with : (edit: added

I wonder if there is such a thing as mouse movement events in NCurses, and if there is a way to catch them. Following the Interfacing with the mouse (from the NCurses programming HOWTO ) it seems that by enabling the REPORT_MOUSE_POSITION bit in the call to mousemask , one can indeed catch mouse movement events. So, I tried that and it does not seem to work. I have something like this: int ch, count=0; mmask_t old; initscr (); noecho (); cbreak (); mousemask (ALL_MOUSE_EVENTS | REPORT_MOUSE_POSITION, &old); keypad (stdscr, TRUE); while ((ch = getchar ()) != 'q') { count++; if (ch == KEY_MOUSE)

I have been looking for an equivalent to kbhit() and I have read several forums on this subject, and the majority seems to suggest using ncurses. How should I go about checking if a key is pressed in c++ using ncurses. The function getch() provided by ncurses reads character from the window. I would like to write a function that only checks if there is a key press and then I want to do getch(). Thanks in advance. You can use the nodelay() function to turn getch() into a non-blocking call, which returns ERR if no key-press is available. If a key-press is available, it is pulled from the input

I'm having some problems getting ncurses' getch() to block. Default operation seems to be non-blocking (or have I missed some initialization)? I would like it to work like getch() in Windows. I have tried various versions of timeout(3000000); nocbreak(); cbreak(); noraw(); etc... (not all at the same time). I would prefer to not (explicitly) use any WINDOW , if possible. A while loop around getch(), checking for a specific return value is OK too. The curses library is a package deal. You can't just pull out one routine and hope for the best without properly initializing the library. Here's a

The title is a bit more specific than my actual goal: I have a command-line program which uses GNU Readline, primarily for command history (i.e. retrieving previous commands using up-arrow) and some other niceties. Right now the program's output appears interspersed with the user's input, which sometimes is OK but the output is asynchronous (it comes via a network connection in response to the input commands), and that gets annoying sometimes (e.g. if lines are output when the user is typing new input). I'd like to add a feature to this program: a separate "window" for the output. I thought

对官方提供的内核源码包进行解压缩，进入到内核目录，使用make menuconfig后，发现提示以下错误： *** Unable to find the ncurses libraries or the *** required header files. *** 'make menuconfig' requires the ncurses libraries. *** *** Install ncurses (ncurses-devel) and try again. *** make[1]: *** [scripts/kconfig/dochecklxdialog] Error 1 make: *** [menuconfig] Error 2 1 2 3 4 5 6 7 8 参考 apt-get install libncurses5-dev 1 发现，并不起作用。 网上查了一下，发现以下命令有用。 sudo apt-get install ncurses-dev原文来自：http://blog.csdn.net/moluoyu/article/details/51504214 来源： https://www.cnblogs.com/moaiwa/p/8151626.html
