Leap提供了SDK。但是整合有很多的问题，写博客记录一下；
写一个类：SampleListener.cpp以及头文件SampleListener.h。
这里主要碰到的问题是找不到以及冲突问题；
这里最关键的是用的不能写using namespace Lead。必须写Lead::这种形式。
代码如下：
#include <iostream>
#include <cstring>
#include "Leap.h"
//using namespace Leap;
class SampleListener : public Leap::Listener {
public:
int civiv;//手机识别的标志
void onInit(const Leap:: Controller&);
void onConnect(const Leap::Controller&);
void onDisconnect(const Leap:: Controller&);
void onExit(const Leap:: Controller&);
void onFrame(const Leap:: Controller&);
void onFocusGained(const Leap:: Controller&);
void onFocusLost(const Leap::Controller&);
void onDeviceChange(const Leap:: Controller&);
void onServiceConnect(const Leap:: Controller&);
void onServiceDisconnect(const Leap:: Controller&);
void onStart(); private:
};
SampleListener.cpp:
#include "stdafx.h"
#include "SampleListener.h"

嵌入师兄的MFC写的程序中:
注意因为与师兄写的变量冲突，所以这里不能写using namespace Lead。必须写Lead::这种形式。
EyeTrackView.h:
#include "TshirtCode.h"
#include "TshirtDraw.h"
#include "GeneticAlgorithm.cpp"
#include "CvvImage.h"
#include <deque>
#include "shockwaveflash1.h"
#include "pupilDetector.h"
#include "Device.h"
#include "communication.h"
#include "DeviceEyeDataAnalyze.h"
#include "HardWord.h"
#include "SampleListener.h"
EyeTrackView.cpp照常引入EyeTrackView.h。
