Description

The class extended-selection-tree-view is like tree-view but allows more than one item to be selected at once.

Notes

1. 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.
2. The delete item callback (see delete-item-callback in tree-view) is called in extended-selection-tree-view with the second argument being a list of the selected items, unless interaction is :single-selection, in which case it behaves the same as in tree-view.
