6.字符属性与颜色

7.输出字符串

#include <curses.h>
#include <unistd.h>

int main(int argc, const char *argv[])
{
    initscr();
    box(stdscr,0,0);

    start_color();    //初始化颜色
    init_pair(1,COLOR_CYAN,COLOR_WHITE);   //定义颜色对，init_pair()一定要放在start_color()后面
    init_pair(2,COLOR_RED,COLOR_BLACK);
    init_pair(3,COLOR_BLACK,COLOR_BLUE);


    bkgd(COLOR_PAIR(3));  //设置背景色

    mvaddch(2,10,ACS_PI|COLOR_PAIR(1));
    mvaddch(4,10,‘A‘|COLOR_PAIR(2));
    
    attron(COLOR_PAIR(1));  //想要加入下划线，粗体等 可以  COLOR_PAIR(1)|A_BOLD 等
    mvaddstr(6,10,"Hello");
    attroff(COLOR_PAIR(1));  //关闭属性 ，不一定要全部关闭，可以关闭你要的属性

    attron(COLOR_PAIR(2));
    mvprintw(8,10,"PID is %d\n",getpid());
    mvprintw(9,10,"lines:%d cols:%d\n",LINES,COLS);
    attroff(COLOR_PAIR(2));

    getch();

    endwin();
    return 0;
}

#include <curses.h>
#include <time.h>
#include <unistd.h>

void init();
void drawui();
void business();
void destroy();

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

}

void drawui()

    box(stdscr,0,0);
    bkgd(COLOR_PAIR(1));
}

void business()
{
    time_t tt;
    struct tm *t;
    while(1)
    {

        sleep(1);//停一秒钟
    }

{

    refresh();

}

8.输入

#include <curses.h>

int main(int argc, const char *argv[])
{
    initscr();
    int ch;

    noecho();

    while(1)
    {
        ch = mvgetch(5,10);
        mvprintw(8,10,"you input is:%c",ch);
    }

    endwin();
    return 0;
}

#include <curses.h>

int main(int argc, const char *argv[])
{
    int ch;
    int x,y;
    initscr();
    keypad(stdscr,TRUE);
    
    noecho();
    y = LINES/2;
    x = COLS/2;
    mvaddch(y,x,‘A‘);

    while(1)
    {
        ch = getch();
        mvaddch(y,x,‘ ‘);//等同于erase() ,也可用clear()
        switch(ch)
        {
        case KEY_UP:
            y--;
            break;
        case KEY_DOWN:
            y++;
            break;
        case KEY_LEFT:
            x--;
            break;
        case KEY_RIGHT:
            x++;
            break;
        }
        mvaddch(y,x,‘A‘);
        refresh();
    }

    endwin();
    return 0;
}

#include <curses.h>

int main(int argc, const char *argv[])
{
    char name[9];
    char pass[9];

    memset(name,0,9);

    initscr();
    
    mvaddstr(4,10,"user:[        ]");
    mvgetnstr(4,16,name,8);


    mvprintw(7,10,"your input is:%s\n",name);

    refresh();
    getch();

    
    endwin();
    return 0;
}

#include <curses.h>

void init();
void drawUi();
void dealInput();
void destroy();

int main(int argc, const char *argv[])
{
    init();
    drawUi();
    dealInput();
    destroy();

    return 0;
}

void init()
{
    initscr();
}

void destroy()
{
    endwin();
}

void drawUi()
{
    mvaddstr(2,2,"[     ]+[     ]=[      ]");
    refresh();
}

void dealInput()
{
    int a,b;
    while(1)
    {
        mvaddstr(2,2,"[     ]+[     ]");
        mvscanw(2,3,"%d",&a);
        mvscanw(2,11,"%d",&b);
        mvprintw(2,19,"%d",a+b);
        refresh();
    }

}

9.清屏

int erase(void); 相当与上面例子2中用的清屏，拷贝一个空白字符进去

int clear(void);  把整个清掉

int clrtobot(void); 从当前位置删到最后一行

int clrtoeol(void);从当前位置删到行尾

10.光标控制

11.创建窗口

#include <curses.h>

int main(int argc, const char *argv[])
{
    WINDOW *w;
    initscr();
    box(stdscr,0,0);

    w=derwin(stdscr,4,20,5,3);
    box(w,0,0);

    refresh();
    wrefresh(w);
    getch();

    endwin();
    return 0;
}
