#include "ltwrappr.h"

LVectorPolyDraw::LVectorPolyDraw(pPolyDraw = NULL)

LVectorPolyDraw::LVectorPolyDraw(pObject, pVector =NULL)

pVECTORPOLYDRAW pPolyDraw;	/* pointer to a VECTORPOLYDRAW structure */
pVECTOROBJECT pObject;	/* pointer to a VECTOROBJECT structure */
LVectorBase *pVector;	/* pointer to an LVectorBase object */

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

Parameter	Description
pPolyDraw	Pointer to a VECTORPOLYDRAW structure that contains information used to create and initialize the new vector polydraw object.
pObject	Pointer to a VECTOROBJECT structure that contains information used to create and initialize the new vector polydraw object.
pVector	Pointer to an LVectorBase object with which the newly constructed vector polydraw object will be associated.

Returns

None

Comments

LVectorPolyDraw::LVectorPolyDraw(pPolyDraw) is a constructor for the LVectorPolyDraw object. It takes a valid pVECTORPOLYDRAW pointer and creates an LVectorPolyDraw object.

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

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