LVectorEllipse::LVectorEllipse

#include "ltwrappr.h"

LVectorEllipse::LVectorEllipse(pEllipse = NULL)

LVectorEllipse::LVectorEllipse(pObject, pVector =NULL)

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

Parameters

pVECTORELLIPSE pEllipse

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

pVECTOROBJECT pObject

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

LVectorBase *pVector

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

Returns

None.

Comments

LVectorEllipse::LVectorEllipse(pEllipse) is a constructor for the LVectorEllipse object. It takes a valid pVECTORELLIPSE pointer and creates an LVectorEllipse object.

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

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