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
