LVectorHPolyBezier::LVectorHPolyBezier

Summary

Constructs and initializes the different member variables of the LVectorHPolyBezier object.

Syntax

LVectorHPolyBezier::LVectorHPolyBezier(pHPolyBezier = NULL)

LVectorHPolyBezier::LVectorHPolyBezier(pObject, pVector =NULL)

Parameters

pVECTORHPOLYBEZIER pHPolyBezier

Pointer to a VECTORHPOLYBEZIER structure that contains information used to create and initialize the new vector line object.

pVECTOROBJECT pObject

Pointer to a VECTOROBJECT structure that contains information used to create and initialize the new vector HPolyBezier object.

LVectorBase *pVector

Pointer to an LVectorBase object with which the newly constructed vector HPolyBezier object will be associated.

Returns

None.

Comments

LVectorHPolyBezier::LVectorHPolyBezier(pHPolyBezier) is a constructor for the LVectorHPolyBezier object. It takes a valid pVECTORHPOLYBEZIER pointer and creates an LVectorHPolyBezier object.

LVectorHPolyBezier::LVectorHPolyBezier(pObject, pVector=NULL) creates an LVectorHPolyBezier object based on the information provided in pObject and associates the newly created LVectorHPolyBezier object with the specified LVectorBase object. This constructor can be used with the LVectorLayer::EnumObjects function, which returns a valid pVECTOROBJECT pointer in the LVectorLayer::EnumObjectsCallBack member function. It can also be used with LVectorBase::VectorEventProcCallBack, which can also return a pObject.

Note that it is possible to construct an invalid LVectorHPolyBezier object using the LVectorHPolyBezier::LVectorHPolyBezier(pObject, pVector=NULL) constructor. For example:

   //pObject->nType == type other than VECTOR_HPOLYBEZIER   
   //LVectorBase *pVector is valid   
   LVectorHPolyBezier MyVectorHPolyBezier(pObject, pVectorBase);   
   if (MyVectorHPolyBezier.IsTypeValid() == FALSE)   
      MessageBox(NULL, TEXT("Invalid Vector Object"), TEXT(""), MB_OK);
