 I would suggest to make the second argument 'const SfxPoolItem **ppItem = 0', 
not only to keep it consistent with GetItemState(), but also to make it more 
visible that it is an out argument. The intuitive reading of "if( 
set.HasItem( which, item ))" to me is "does 'set' have an item of 
type 'which' that is 'item'?".
