A pane that displays a hierarchical list of items which (unlike tree-view) allows extended selection.
The class
extended-selection-tree-view
is like tree-view but allows more than one item to be selected at once.
Although
extended-selection-tree-view
is a subclass of collection, it does its own items handling and you must not access its
items
and related slots directly. In particular for
extended-selection-tree-view
do not pass
:items
,
:items-count-function
,
:items-get-function
or
:items-map-function
, and do not use the corresponding accessors.
