Tree

class Tree[A](var treeDataModel: TreeModel[A])(implicit evidence$1: ClassTag[A]) extends Component with CellView[A] with EditableCells[A] with RenderableCells[A] with Wrapper

Wrapper for a JTree. The tree model is represented by a lazy child expansion function that may or may not terminate in leaf nodes.

The tree publishes structural events, such as nodes being added or removed, on its main publisher, whereas selection changes are published to the dedicated Tree#selection object.

object selection extends CellSelection

Selection model for Tree.

Selection model for Tree.

To observe tree selections, make the reactor listen to this publishing object which will then dispatch instances of scalaswingcontrib.event.TreePathSelected.

trait CellSelection extends Publisher

Provides common functionality for the selection object found in CellView implementation. Each will have one or more selection sets based on different types of cell coordinate, such as row, column, index or tree path. All events published from selection objects will derive from scala.swing.event.SelectionEvent.

implicit def genericEditor[B]: Editor[B]

Implicit method to produce a generic editor. This lives in the Tree class rather than the companion object because it requires an actual javax.swing.JTree instance to be initialised.

implicit def pathToTreePath(p: IndexedSeq[A]): TreePath

Implicitly converts Tree.Path[A] lists to TreePath objects understood by the underlying peer JTree. In addition to the objects in the list, the JTree's hidden root node must be prepended.
