I have a small ncurse program I'm running, but the output doesn't seem to show up unless I stick the wrefresh() in a while loop.
Is there some buffering going on or something? I tried other refresh functions in the library and fflush with stddout (which I don't think makes sense, but worth a try), but nothing seems to work.
A second small question: to make getch() non-blocking we need to call nodelay(win,TRUE), right?
void main()
{
initscr();
start_color();
init_pair(1,COLOR_YELLOW,COLOR_CYAN);
WINDOW *win = newwin(10,10,1,1);
wbkgd(win,COLOR_PAIR(1));
wprintw(win,"Hello, World.");
wrefresh(win);
getch();
delwin(win);
endwin();
}
Answer
You are not supposed to mix operations on stdscr and windows created with newwin(). getch() operates on stdscr, so that is your problem. Replace that call with
wgetch(win);
(getch() is causing stdscr to be dumped over the top of your other window, and because that happens so quickly it looks like the other window never got displayed at all).
