#include "ltwrappr.h"

virtual L_UINT LAnnPolygon::GetFillMode(puFillMode, pnAlpha)

L_UINT * puFillMode;	pointer to a variable to be updated with the fill mode
L_INT * pnAlpha;	pointer to a variable to be updated with the alpha value

Gets the fill mode and alpha of the specified annotation object.

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)
