Java Foundation Classes in a Nutshell

CHAPTER 34

Thejavax.swing.tree Package

The javax.swing .tree package defines classes and interfaces used with the

javax.swing .JTree component. The TreeModel inter face defines the data to be displayed

by a JTree component. DefaultTreeModel pr ovides a commonly used implementation

of this interface; it is implemented in terms of the TreeNode and MutableTreeNode

inter faces. The TreeCellRenderer and TreeCellEditor inter faces ar e implemented by

objects that can display or edit cells in the tree, using a Swing component as a

template. Figure 34-1 shows the class hierarchy of this package. See Chapter 3,

Swing Programming Topics, for a discussion of and example using JTree and the

javax.swing .tree package.

AbstractLayoutCache Ja va 1.2

javax.swing .tree

This abstract class defines the methods that must be implemented by a class that wants

to cache a JTree layout. This class is used by the JTree UI delegate. Applications never

need to use or subclass this class.
