Class TreeState

java.lang.Object

com.iamsoft.util.ui.swing.TreeState

All Implemented Interfaces:

Serializable

public class TreeState
extends Object
implements Serializable

Used to capture the state of a JTree. Useful if treemodel is changing and one doesn't want tree selections and node expansions to be lost. Could also be used to restore a JTree in between application invocations. Identify lead selection, selected elements and expanded paths. Since selection paths are stored (rather than rows), restoration should remain possible after simplistic tree updates such as node deletion, insertion and rearrangement. TODO: Improve deletion handling, general debugging, anchor path, handle anchor/lead
