Names are used in many different contexts.
We use the extraction operator, [, typically to refer to
the underlying items from which a selection can be made. As well,
we overload this to containers to refer to the child components.
The update method will ca use a widget to recompute itself, if it is necessary.
The current items for a gdf object are both the visible and
non-visible items. To retrieve just the currently visible items,
use the idiom obj[visible(obj), ].
The underlying widget may allow autocompletion, if this is the case then this method is used to set the list of candidates.
