Example

This example creates an array of selected items and rotates each one. Note that this can also be done simply by setting a flag in L_AnnRotate.

L_INT AnnGetSelectItemsExample(HANNOBJECT   hContainer)/* Container annotation object */ 
{ 
   L_INT nRet; 
  L_UINT       uSelectCount;  /* Number of objects selected */      
  pHANNOBJECT  pAnnArray;     /* Pointer to an array of annotation objects */    
  HGLOBAL      hAnnArray;     /* Handle for memory management */  
  L_UINT       i;             /* Loop counter */ 
 
  /* Get the number of objects selected */ 
  nRet = L_AnnGetSelectCount(hContainer, &uSelectCount);    
  if(nRet != SUCCESS) 
     return nRet; 
  /* Allocate and lock a storage for the object handles */ 
  hAnnArray = GlobalAlloc(GPTR, sizeof(HANNOBJECT) * uSelectCount); 
  pAnnArray = (pHANNOBJECT)GlobalLock( hAnnArray ); 
  /* Fill the array of selected objects */ 
  nRet = L_AnnGetSelectItems(hContainer, pAnnArray); 
  if(nRet != SUCCESS) 
     return nRet; 
  /* Rotate each selected object */ 
  for (i = 0; i < uSelectCount; i++) 
  { 
    nRet = L_AnnRotate(pAnnArray[i], 90, 0, 0); 
    if(nRet != SUCCESS) 
       return nRet; 
  } 
  /* Free the memory */ 
  GlobalUnlock (hAnnArray); 
  GlobalFree (hAnnArray); 
   return SUCCESS; 
}
