AS400TreeModel

java.lang.Object
- com.ibm.as400.vaccess.AS400TreeModel

All Implemented Interfaces:

java.io.Serializable, javax.swing.tree.TreeModel

Deprecated.
Use Java Swing instead, along with the classes in package com.ibm.as400.access
```
public class AS400TreeModel
extends java.lang.Object
implements javax.swing.tree.TreeModel, java.io.Serializable
```
The AS400TreeModel class implements an underlying model for a tree, where all information for the tree is gathered from the hierarchy of objects rooted at a system resource. You must explicitly call load() to load the information from the system.
Use this class if you want to customize the graphical user interface that presents a tree. If you do not need to customize the interface, then use AS400TreePane instead.
Most errors are reported as ErrorEvents rather than throwing exceptions. Users should listen for ErrorEvents in order to diagnose and recover from error conditions.
AS400TreeModel objects generate the following events:
- ErrorEvent
- PropertyChangeEvent
- TreeModelEvent
- WorkingEvent
The following example creates a tree model filled with the list of printers on a system. It then presents the tree in a JTree object.
```
//Set up the tree model and JTree.
AS400 system = new AS400 ("MySystem", "Userid", "Password");
VPrinters printers = new VPrinters (system);
AS400TreeModel treeModel = new AS400TreeModel (printers);
treeModel.load ();
JTree tree = new JTree (treeModel);


// Add the JTree to a frame.
JFrame frame = new JFrame ("My Window");
frame.getContentPane().add(new JScrollPane(tree));
```
