[.GDefaultWidget {gWidgets2}

Return items

Description

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.
