Example

This example will toggle the selection state of the object under a given 2D point.

L_INT LVectorObject__IsObjectSelectedExample(HWND hWnd, LVectorBase *pVector, LPPOINT pPoint)
{
   UNREFERENCED_PARAMETER(hWnd);
   L_INT          nRet;
   LVectorObject  VectorObject;    /* Object under point */
   // Get object under that point 
   nRet = pVector->HitTest(pPoint, &VectorObject);
   //Is there an object under that point? If yes, select it
   if (nRet == SUCCESS)
   {
      L_BOOL bSelected;
      nRet = VectorObject.IsObjectSelected(&bSelected);
      if(nRet != SUCCESS)
         return nRet;
      nRet = VectorObject.SelectObject(!bSelected);
      if(nRet != SUCCESS)
         return nRet;
   }
   else
      return nRet;
