Example

This example displays the total number of objects in each group in a vector.

class LMyVectorGroup1: public LVectorGroup 
{ 
public: 
   L_INT          m_nObjectCount ; 
 
public: 
   LMyVectorGroup1() {m_nObjectCount=0;}; 
   virtual ~LMyVectorGroup1(){}; 
   virtual L_INT  EnumObjectsCallBack( pVECTORHANDLE pVector, pVECTOROBJECT pObject); 
}; 
 
L_INT LMyVectorGroup1::EnumObjectsCallBack( pVECTORHANDLE pVector, pVECTOROBJECT pObject) 
{ 
   UNREFERENCED_PARAMETER(pVector); 
   UNREFERENCED_PARAMETER(pObject); 
 
   m_nObjectCount++; 
   return SUCCESS; 
}
