如何在点击后显示X，Y共同点并在控制台中显示

Question

我已经学习了两个多星期的C++，现在我正在努力通过编写一个简单的控制台应用程序显示了我的鼠标光标的Y坐标，我查看了MSDN的Libs，并试图合理化，但我所做的只是以错误的方式显示合作伙伴。

这里是我现在的代码，它不是很多，但我想确保我以正确的方式做事情，所以我没有选择坏习惯;

#include <iostream> 
#include <Windows.h> 

int main() 
{ 
POINT cursorPos; 
GetCursorPos(&cursorPos); 
printf("X %d Y %d\n", cursorPos.x, cursorPos.y); 


system("PAUSE"); 
} 

这样做的主要目的是让开放的控制台（运行一次），并聆听左点击，然后显示该联合ORD在控制台，直至其再次点击！

对此的任何帮助将不胜感激，并抱歉，如果这已被张贴在某处之前，我已经尝试搜索，但没有运气！

Answer 1

尝试是这样的：

#include <iostream> 
#include <Windows.h> 

int main() 
{ 
    POINT cursorPos; 

    do 
    { 
     GetCursorPos(&cursorPos); 
     printf("X %d Y %d\n", cursorPos.x, cursorPos.y); 
     Sleep(100); 
    } 
    while (cursorPos.x != 0 || cursorPos.y != 0); 

    // just "for fun", as an example, 
    // you have to set your mouse to X=0, Y=0 to exit! 

    return 0; 
} 

的事情是：一个程序只是操作的顺序，所以“，如果它完成它做什么..它死了！“

当一个程序处于活动状态时，这意味着它实际上正在“事件循环”中运行。它意味着一个“保持程序活着”的循环。它有很多名字取决于你正在使用的系统/平台（例如，在OS X中，它被称为RunLoops），但它们都是一样的想法。

这个“事件循环”的基本概念基本上总是一样的：观察用户输入，观察系统输入，并根据输入做一些动作（很多时候，动作只是“睡眠！“）

用这种方法。你的程序将永远活着！直到它响应意味着“关闭”的输入。 （例如，在Windows中，当您使用Windows或ESC键，控制台模式等时，它可能是WM_QUIT消息...）

就是这个例子，我刚刚给出了“作为示例“如果鼠标位置变为(x=0, y=0)，则退出。

使用键盘和鼠标的控制台自己的事件处理程序 - ReadConsoleInput()
