OpenCV中的cvSetMouseCallback 2.1托管C ++（CLI / C ++）

我把委托在HandMotionRecognition.h中的MouseCallbackDelegate（int event，int x，int y，int flags，void * param）;

我把这段代码放在HandMotionRecognition.cpp中，而不是 cvSetMouseCallback（CameraIn，& HandMotionRecognition :: getColorPixel，（void *）frameHSV）;

I put this code in HandMotionRecognition.cpp instead of cvSetMouseCallback( "CameraIn", &HandMotionRecognition::getColorPixel, (void*) frameHSV);

cvSetMouseCallback（CameraIn，StaticDelInst，（void *）frameHSV）;

cvSetMouseCallback( "CameraIn", StaticDelInst, (void*) frameHSV);

但是它会给出编译错误：（这是我唯一的错误）

But it then gives the compile error: (this is the only error I get)

错误C2664：'cvSetMouseCallback'：无法将参数2从HandMotionRecognition :: MouseCallbackDelegate ^转换为CvMouseCallback

error C2664: 'cvSetMouseCallback' : cannot convert parameter 2 from 'HandMotionRecognition::MouseCallbackDelegate ^' to 'CvMouseCallback'

（至于我可以看到...这是由于使用cli而不是win32）

(As for as I can see..this is due to using cli instead of win32)

有没有一个工作，或我是在这里做错事？

Is there a work-around this or am i doing something wrong here???

请帮助...

p>回调方法必须是您发现的静态（或非成员函数）。在这种情况下，标准成语是将类实例指针传递给 void * param 参数，并使用 static 函数调用成员函数。由于您正在使用 param 来存储 frameHSV ，您需要以其他方式传输（例如，将其存储在你的课堂实例）。

The callback method has to be static (or a non-member function) as you've discovered. The standard idiom in this case is to pass the class instance pointer in the void* param parameter and use a static function to call the member function. Since you're currently using param to store frameHSV you need to transfer that some other way (e.g. by storing it in your class instance).
