list-panel-items-and-filter

Description

The function list-panel-items-and-filter accesses the unfiltered items and the state of the filter in the list panel list-panel simultaneously. It is especially useful for setting the filter state and the items without flickering.

list-panel-items-and-filter returns the items and filter state in list-panel as multiple values. It is equivalent to


(values (list-panel-unfiltered-items 
list-panel
) (list-panel-filter-state 
list-panel
))

but is more efficient.

The return value filter-state is the same type as the state that is used in filtering-layout.

(setf list-panel-items-and-filter) takes the items and new filter state as two values and sets them in list-panel :

These two forms:


(setf (list-panel-items-and-filter 
list-panel
) (values 
new-items
 
new-filter-state
))


(progn (setf (list-panel-unfiltered-items 
list-panel
) 
new-items
) (setf (list-panel-filter-state 
list-panel
) 
new-filter-state
))

have the same ultimate effect on list-panel , but the latter form will filter the new-items with the old filter and display the result and then filter the new-items again with the new-filter-state , whereas (setf list-panel-items-and-filter) filters the new-items just once, with the new-filter-state .
