首先構造一個僅帶輸入功能的編輯器，使用wgetch來捕捉輸入。

#include

#include

#include

int main(int argc, char *argv[])

{

setlocale(LC_ALL,"");

initscr();

clear();

noecho();

cbreak();

if(has_colors() == FALSE)

{

endwin();

printf("你的終端不支持色彩！\n");

return (1);

}

start_color(); /*啟動color 機制*/

init_pair(1, COLOR_GREEN, COLOR_BLACK);

WINDOW *win1;

int width=COLS-14;

int height=LINES-14;

int x,y;

win1=newwin(height,width,7,7);//新窗口(行，列,begin_y,begin_x)

keypad(win1,TRUE);

box(win1,ACS_VLINE,ACS_HLINE);

wattron(win1,COLOR_PAIR(1));

wrefresh(win1);

getyx(win1,y,x);

++y;++x;

while(1){

int c=mvwgetch(win1,y,x);

++x;

if (x>=width-1){

++y;

x=1;

}

if (y>=height-1){

y=1;

}

mvwprintw(win1,y,x,"%c",c);

wrefresh(win1);

}

wattroff(win1,COLOR_PAIR(1));

endwin();

return 0;

}
