准备工作
腾讯云服务器（Ubuntu），C++编程语言
由于想输出界面中包含中文，所以安装库 libncursesw5，依次输入下面三行命令
sudo apt-get install libncursesw5 sudo apt-get install libncursesw5-dbg sudo apt-get install libncursesw5-dev
编译用如下命令
g++ main.cpp -l ncursesw
ToDoList小工具开发
思路
由于一开始想的就比较多，想做一个工具箱，所以Todolist工具只是其中的一个，这样的话用c++每个小工具封装成一个类肯定更适合。
主程序很简单，都用一个套路，注意由于要输出中文，所以头文件有locale.h, 主程序中也添加了setlocale(LC_ALL,"")
1 #include <iostream>
2 #include <ncurses.h>
3 #include <locale.h>
4 #include "tool.h"
5 #include "todolist.h"
6 using namespace std;
7
8
9 int main()
10 {
11 setlocale(LC_ALL,"");
12 initscr();
13 cbreak();
14 noecho();
15 curs_set(0);
16 keypad(stdscr,TRUE);
17
18 refresh();
19
20 TODOLIST *tt = new TODOLIST();
21 tt->display();
22
23
24 getch();
25 endwin();
26 return 0;
27
28 }
注意到头文件中有两个自己设定的类tool和todolist
tool类
这里面主要放一些通用的，或者用的比较多的功能，如创建一个窗口，销毁一个窗口，获取当前时间等。
1 #ifndef _TOOL_H_
2 #define _TOOL_H_
3 #include <string>
4 #include <sstream>
5 #include <ctime>
6 #include <ncurses.h>
7 using namespace std;
8
9 class TOOL
10 {
11 public:
12 string int2str(int num);
13 string getCurrentDate();
14 WINDOW *create_newwin(int height, int width, int starty, int startx);
15 void destory_win(WINDOW *local_win);
16 };
17
18 #endif
#include "tool.h"
string TOOL::int2str(int num)
{
stringstream stream;
stream<<num;
return stream.str();
}
string TOOL::getCurrentDate()
{
time_t rawtime;
struct tm *ptminfo;
time(&rawtime);
ptminfo = localtime(&rawtime);
string ss="时间："+int2str(ptminfo->tm_year+1900)+"年"+int2str(ptminfo->tm_mon+1)+"月"
+int2str(ptminfo->tm_mday)+"日";
return ss;
}
WINDOW *TOOL::create_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 TOOL::destory_win(WINDOW *local_win)
{
wborder(local_win, ‘ ‘, ‘ ‘, ‘ ‘, ‘ ‘, ‘ ‘, ‘ ‘, ‘ ‘, ‘ ‘);
wrefresh(local_win);
delwin(local_win);
}
TODOLIST类
这里面就是我们小工具的功能实现
一个简单的todolist我在这里分成了四个部分，标题，未完成，已完成，输出/显示窗口，因此要建立四个窗口
每个窗口的尺寸位置都要注意分配。
1 #ifndef _TODOLIST_H_
2 #define _TODOLIST_H_
3 #include <ncurses.h>
4 #include "tool.h"
5 #include <string>
6 #include <cstring>
7 using namespace std;
8
9 class TODOLIST
10 {
11 public:
12 TODOLIST();
13 ~TODOLIST();
14 void display();
15
16 TOOL tool;
17 WINDOW *title_win, *todo_win, *done_win, *info_win;
18
19 int title_win_h, title_win_w, title_win_y, title_win_x;
20 int todo_win_h, todo_win_w, todo_win_y, todo_win_x;
21 int done_win_h, done_win_w, done_win_y, done_win_x;
22 int info_win_h, info_win_w, info_win_y, info_win_x;
23 };
24 #endif
1 #include "todolist.h"
2
3 TODOLIST::TODOLIST()
4 {
5 title_win_h = 3;
6
7 title_win_y = 0;
8 title_win_x = 0;
9
10 todo_win_h = 20;
11 todo_win_w = 40;
12 todo_win_y = title_win_y + title_win_h + 1;
13 todo_win_x = 0;
14
15 done_win_h = todo_win_h;
16 done_win_w = todo_win_w;
17 done_win_y = todo_win_y;
18 done_win_x = todo_win_x + todo_win_w + 1;
19
20 info_win_h = 3;
21
22 info_win_y = todo_win_y + todo_win_h + 1;
23 info_win_x = 0;
24
25 title_win_w = todo_win_w + done_win_w + 1;
26 info_win_w = title_win_w;
27 }
28
29 void TODOLIST::display()
30 {
31 //显示标题窗口
32 title_win = tool.create_newwin(title_win_h,title_win_w,title_win_y,title_win_x);
33 char currdate[128];
34 string title;
35 title = tool.getCurrentDate() + " " + "ToDoList 1.0 by 大蓝鲸";
36 strcpy(currdate,title.c_str());
37
38 mvwprintw(title_win,1,1, currdate);
39 wrefresh(title_win);
40
41 //待办事项窗口
42 todo_win = tool.create_newwin(todo_win_h,todo_win_w,todo_win_y,todo_win_x);
43 mvwprintw(todo_win, 0, 2, "未完成事项");
44 wrefresh(todo_win);
45
46 //已完成事项窗口
47 done_win = tool.create_newwin(done_win_h,done_win_w,done_win_y,done_win_x);
48 mvwprintw(done_win, 0, 2, "已完成事项");
49 wrefresh(done_win);
50
51 //信息提示窗口
52 info_win = tool.create_newwin(info_win_h,info_win_w,info_win_y,info_win_x);
53 mvwprintw(info_win, 0, 2, "提示");
54 wrefresh(info_win);
55 }
56
57 TODOLIST::~TODOLIST()
58 {
59
60 }
编译运行
g++ *.h *.cpp -l ncursesw
./a.out
运行结果
