LVectorStock::LVectorStock

#include "ltwrappr.h"

LVectorStock::LVectorStock(pStock = NULL)

LVectorStock::LVectorStock(pObject, pVector =NULL)

pVECTORSTOCK pStock;	/* pointer to a VECTORSTOCK structure */
pVECTOROBJECT pObject;	/* pointer to a VECTOROBJECT structure */
LVectorBase *pVector;	/* pointer to an LVectorBase object */

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

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

Returns

None

Comments

LVectorStock::LVectorStock(pStock) is a constructor for the LVectorStock object. It takes a valid pVECTORSTOCKpointer and creates an LVectorStock object.

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

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

Example

This is an example for LVectorStock::LVectorStock(pStock):

This example will add all of the stock objects from VecOfice.dll to the Active Layer of an LVectorBase object.

For an example for LVectorStock::LVectorStock(pObject, pVector=NULL), refer to LVectorArc::LVectorArc(pObject, pVector = NULL).
