Example

This example gets and updates the property of the object passed by the caller

L_INT LAnnPolygon_GetFillModeExample(LAnnPolygon  * pAnnObject)
{
   L_INT nRet;
   L_UINT uFillMode; /* Object fill mode */
   /* Set the fill mode to transparent, unless it already is */
   nRet = pAnnObject->GetFillMode(&uFillMode, NULL);
   if (nRet != SUCCESS)
      return nRet;
   if (uFillMode == ANNMODE_TRANSPARENT)
       MessageBox (NULL, TEXT("Already transparent"), TEXT("Notice"), MB_OK);
   else
   {
      nRet = pAnnObject->SetFillMode(uFillMode, ANNMODE_TRANSPARENT, 0);
      if(nRet != SUCCESS)
         return nRet;
   }
   return SUCCESS;
