Package javax.swing.tree

Provides classes and interfaces for dealing with javax.swing.JTree. You use these classes and interfaces if you want control over how trees are constructed, updated, and rendered, as well as how data associated with the tree nodes are viewed and managed.

Note: Most of the Swing API is not thread safe. For details, see Concurrency in Swing, a section in The Java Tutorial.
