LVectorPolyBezier::LVectorPolyBezier

#include "ltwrappr.h"

LVectorPolyBezier::LVectorPolyBezier(pPolyBezier = NULL)

LVectorPolyBezier::LVectorPolyBezier(pObject, pVector =NULL)

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

Parameters

pVECTORPOLYBEZIER pPolyBezier

Pointer to a VECTORPOLYBEZIER 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 polybezier object.

LVectorBase *pVector

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

Returns

None.

Comments

LVectorPolyBezier::LVectorPolyBezier(pPolyBezier) is a constructor for the LVectorPolyBezier object. It takes a valid pVECTORPOLYBEZIER pointer and creates an LVectorPolyBezier object.

LVectorPolyBezier::LVectorPolyBezier(pObject, pVector=NULL) creates an LVectorPolyBezier object based on the information provided in pObject and associates the newly created LVectorPolyBezier 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 LVectorPolyBezier object using the LVectorPolyBezier::LVectorPolyBezier(pObject, pVector=NULL) constructor. For example:

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