#include<ncurses.h>
WINDOW *creat_newwin(int height,int width,int starty,int startx);
void destroy_win(WINDOW *local_win);
int main(int argc,char *argv[])
{
    WINDOW *my_win;
    int startx,starty,width,height;
    int ch;
    initscr();
    cbreak();
    keypad(stdscr,TRUE);
    height=6;
    width=20;
    starty=(LINES-height)/2;
    startx=(COLS-width)/2;
    printw("press F2 to exit");
    refresh();
    my_win=creat_newwin(height,width,starty,startx);
    while((ch=getch())!=KEY_F(2))
    {
        switch(ch)
        {
            case KEY_LEFT:
                destroy_win(my_win);
                my_win=creat_newwin(height,width,starty,--startx);
                break;
            case KEY_RIGHT:
                destroy_win(my_win);
                my_win=creat_newwin(height,width,starty,++startx);
                break;
            case KEY_UP:
                destroy_win(my_win);
                my_win=creat_newwin(height,width,--starty,startx);
                break;
            case KEY_DOWN:
                destroy_win(my_win);
                my_win=creat_newwin(height,width,++starty,startx);
                break;
        }
    }
    endwin();
    return 0;
}

WINDOW *creat_newwin(int height,int width,int starty,int startx)
{
    WINDOW *local_win;
    local_win=newwin(height,width,starty,startx);
    box(local_win,0,0);
    wrefresh(local_win);
    return local_win;
}

void destroy_win(WINDOW *local_win)
{
    wborder(local_win,' ',' ',' ',' ',' ',' ',' ', ' ');
    wrefresh(local_win);
    delwin(local_win);
}

效果图是这个样的：

可以移动上下左右键来控制：
