LVectorPie::LVectorPie

#include "ltwrappr.h"

L_VOID LVectorPie::LVectorPie(pPie = NULL)

L_VOID LVectorPie::LVectorPie(pObject, pVector =NULL)

pVECTORPIE pPie;	/* pointer to a VECTORPIE structure */
pVECTOROBJECT pObject;	/* pointer to a VECTOROBJECT structure */
LVectorBase *pVector;	/* pointer to an LVectorBase object */

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

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

Returns

None.

Comments

LVectorPie::LVectorPie(pPie) is a constructor for the LVectorPie object. It takes a valid pVECTORPIE pointer and creates an LVectorPie object.

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

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