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; 
}
