Accesses the state of the filter in a filtered list-panel.
The generic function list-panel-filter-state accesses the state of the filter in a filtered list-panel (that is, a list-panel created with
filter
t).
list-panel-filter-state returns the state of the filter in
list-panel
. The return value
filter-state
is the same type as the state that is used in filtering-layout.
(setf list-panel-filter-state) sets the filter in
list-panel
, filters the unfiltered items and displays those that match the
new-state
. The
new-state
has the same semantics as the
new-value
of (setf filtering-layout-state). It can be a result of a call to list-panel-filter-state or to filtering-layout-state (on a filtering-layout), or a string (meaning plain match, case-insensitive), or nil (meaning match everything).
On an unfiltered list-panel list-panel-filter-state returns nil, and (setf list-panel-filter-state) does nothing.
