public class TreeCell<T> extends IndexedCell<T>
TheCell
type used with theTreeView
control. In addition to the API defined onIndexedCell
, the TreeCell exposes additional states and pseudo classes for use by CSS.A TreeCell watches the selection model of the TreeView for which it is associated, ensuring that it visually indicates to the user whether it is selected. When a TreeCell is selected, this is exposed both via the
selected
property, as well as via the 'selected' CSS pseudo class state.Due to the fact that TreeCell extends from
IndexedCell
, each TreeCell also provides anindex
property. The index will be updated as cells are expanded and collapsed, and therefore should be considered a view index rather than a model index.Finally, each TreeCell also has a reference back to the TreeView that it is being used with. Each TreeCell belongs to one and only one TreeView.
