setSelection( int index) does not exist in the gallery yet, please open 
a bug if you need it.

But you'll get the same result using :
setSelection( galleryGroup.getItem( index ) )

Keep in mind that Gallery is a Tree and groups are root items. So you 
need to call getItem() on the parent group of your item.
