The function
choice-selected-items
returns the currently selected items in a choice as a list of the items.
The function
choice-selected-items
returns the currently selected items in a choice as a list of the items. A
setf
method is provided as a means of setting the currently selected items. Note that the items are compared by
choice
's
test-function
- see collection for details.
In the case of
:single-selection
choices, it is usually easier to use the complementary function choice-selected-item, which returns the selected item as its result.
First we set up a
:multiple-selection
choice -- in this case, a list panel.
(setq list (capi:contain
(make-instance
'capi:list-panel
:items '(a b c d e)
:visible-min-height '(:character 5)
:interaction :multiple-selection
:selection '(1 3))))
The following code line returns the selections of the list.
(capi:choice-selected-items list)
The selections of the list panel can be changed and redisplayed using the following code.
(capi:apply-in-pane-process
list #'(setf capi:choice-selected-items)
'(a c e) list)
(capi:choice-selected-items list)
