基于curses的一个简单例程

最近在linxu下写了一个curses的一个应用程序，感觉不错。使用起来比较方便。大部分都是调用curses的库函数。下面是我使用的例子源码：

#include    

#include     

#include      

#include       

#include    

#include    

 

 

#define StartX  1

#define StartY  1

 

void initial(void)

{

initscr();

  cbreak();

  nonl();

  noecho();

  intrflush(stdscr,FALSE);

  keypad(stdscr,TRUE);

  refresh();

}

 

int main(int argc, char **argv)

{

int x=StartX;

  int y=StartY;

  int ch;

 

 

initial();

  box(stdscr,'|','-');

  attron(A_REVERSE);

  mvaddstr(0,40,"My Curses Program");

  attroff(A_REVERSE);

  move(x,y);

  do {

        ch=getch();

    switch(ch) {

            case KEY_UP:

                --y;

                break;

            case KEY_DOWN:

                ++y;

                break;

            case KEY_RIGHT:

                ++x;

                break;

            case KEY_LEFT:

                --x;

                break;

            case '\r':

                ++y;

                x=1;

                break;

            case '\t':

                x+=7;

                break;

            case 8://判断是否 BACKSPACE

                mvaddch(y,--x,' ');

        break;

      case 27://[ESC]键

          endwin();

          exit(1);

          break;

      default:

                addch(ch);

                x++;

                if(x == 99) {

                    x=1;

                    y++;

                }

                break;

        }

    move(y,x);

    } while (1);

  exit(1);

}

 

以上程序存储为test.c文件；

 

Makefile文件的编写：

 

#all : test.c

test : test.c

    gcc $^ -o $@ -I/usr/include -L/usr/lib -lncurses

clean :

    -rm *.o

 

注意紫色部分代码，若不添加其代码会出现一下错误信息

make: *** [test] Error 1

 

当出现上述错误信息的时候，需要在Makefile文件中编译的时候添加以下语句

 

# gcc test.c -o test -I/usr/include -L/usr/lib -lncurses

 

最后执行./test 即可看到所有执行的结果
