Return items
Length of object
set length of object
dimension of object
Names are used in many different contexts.
set names of object
Get dimnames of object
Set dimnames of object
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.
Return children of a parent container
Set object's items
The update method will ca use a widget to recompute itself, if it is necessary.
str method for widgets
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.
