我尝试在窗口底部输入文本并将其打印在顶部。我这样做了但是当我调整窗口大小时,光标会附加到窗口的底部,当我键入文本时,符号不会在屏幕上回显。如何解决?
抱歉我的英文。
我的代码:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <ncurses.h>
#include <termios.h>
#include <sys/ioctl.h>
#include <signal.h>
WINDOW* txt_win;
WINDOW* msg_win;
void sig_winch(int in) {
struct winsize size;
ioctl(fileno(stdout), TIOCGWINSZ, (char*) &size);
resizeterm(size.ws_row, size.ws_col);
// wprintw(msg_win,"%i, %i", LINES, COLS);
// wmove(msg_win, 0, 0);
// wresize(msg_win, LINES - 4, COLS);
wrefresh(msg_win);
// mvcur(LINES - 3, 0, LINES - 3, 0);
// setsyx(LINES - 3, 0);
// wmove(txt_win, LINES - 3, 0);
// wresize(txt_win, 3, COLS);
wrefresh(txt_win);
echo();
}
int main() {
int x = LINES - 1;
int y = 0;
if (!initscr())
{
fprintf(stderr, "Error initialising ncurses.\n");
exit(1);
}
signal(SIGWINCH, sig_winch);
initscr();
curs_set(1);
refresh();
char str[256];
// dy dx y x
msg_win = newwin(LINES - 4, COLS, 0, 0);
txt_win = newwin(3, COLS, LINES - 3, 0);
keypad(txt_win, 1);
int line = 0;
while (1) {
wrefresh(txt_win);
curs_set(1);
if (wgetnstr(txt_win, str, 256) == 0) {
wclear(txt_win);
curs_set(0);
waddstr(msg_win, str);
wrefresh(msg_win);
}
}
getch();
delwin(txt_win);
delwin(msg_win);
endwin();
}
答案 0 :(得分:0)
有几个问题:
SIGWINCH
,如resizeterm
手册页中所述。SIGWINCH
添加自己的处理程序,则可以(如果您第一次调用keypad(stdscr,TRUE)
)检查KEY_RESIZE
。 KEY_RESIZE
。
