class: TreeItem

[12:7] extends: FxObj

Wraps JavaFX TreeItem, a single node in a TreeView hierarchy that holds a value and an optional set of child TreeItems. Items can be nested to any depth by calling add() with a child TreeItem or a list of them. Each item can carry an optional graphic node such as an icon. The setExpanded() method controls whether the item's children are visible in the tree by default.
