4.6 General properties of choices
The initial selection is controlled with the initarg:selection
. The accessor choice-selection
is provided.
Generally, it is easier to refer to the selection in terms of the items selected, rather than by offsets, so the CAPI provides the notion of a selected item and the selected items. The first of these is the selected item in a single-selection choice. The second is a list of the selected items in any choice.
The accessors choice-selected-item
and choice-selected-items
and the initargs:selected-item
and:selected-items
provide access to these conceptual slots.
