Abstract Value Members
- abstract def branchOption(node: Node): Option[Branch]
Returns this node as a branch, if is one, or None if this node is a leaf.
- abstract def children(branch: Branch)(implicit tx: T): Iterator[Node]
Queries the children of a branch.
- abstract def columnNames: IndexedSeq[String]
- abstract def data(node: Node)(implicit tx: T): Data
Queries the opaque rendering data for a given node.
Queries the opaque rendering data for a given node. The data can be used by the renderer.

- abstract def observe(n: Node, data: Data, dispatch: (T) => (ModelUpdate[Node, Branch]) => Unit)(implicit tx: T): Disposable[T]
After creating a new node view with data obtained by the
datamethod, tells the handler to register listeners that can dispatch tree changes.After creating a new node view with data obtained by the
datamethod, tells the handler to register listeners that can dispatch tree changes. This may also observe the data if it is a dynamic view. In this case, to unregister the listeners, the handler should rely on thedisposemethod of the returnedDisposable. - abstract def renderer(treeTable: TreeTableView[T, Node, Branch, Data], node: NodeView[T, Node, Branch, Data], row: Int, column: Int, state: State): Component
