Class LazyProgressNode<T>

java.lang.Object
javax.swing.tree.DefaultMutableTreeNode
oracle.javatools.ui.tree.lazy.LazyProgressNode<T>

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, javax.swing.tree.MutableTreeNode, javax.swing.tree.TreeNode

public final class LazyProgressNode<T>

extends javax.swing.tree.DefaultMutableTreeNode

implements javax.swing.tree.TreeNode

A LazyProgressNode is a temporary node that appears in a tree as a child of a LazyParentNode. The LazyProcessNode runs the worker that determines the children, and reports progress via the getProgress method. Once the children are fetched the progess node is removed from the tree and the children are inserted.

Progress can be determined and cancelled via a LazyProgressTracker passed to a LazyParentNode
