I am just overriding the following methods in the XMLTreeNode class:-

public boolean equals(Object obj)
public void setParent(javax.swing.tree.MutableTreeNode newParent)
public javax.swing.tree.TreeNode getParent()
public void setUserObject(Object userObject)
public Object getUserObject()
public String toString()

In the equals() method i am comparing the content of the user object which is actually org.jdom.Element.
In the XMLTreeNode class i have private XMLTreeNode parent;, which i am using to set/getparent() methods.
In the set/getUserObject() methods i am setting the nodeElement (private org.jdom.Element nodeElement;)object in the XMLTreeNode class.
In the toString() methog i am returning nodeElement.getTextTrim();

 

 

You might also want to look at dotuseful project and find a similar but easier way to work with trees.

Hehe Denis,

The thought just occured to me that the reloading process I was describing earlier could be a good built-in feature of your AutomatedTreeModel.

 

 

Might be a good idea. Thanks weebib. If there are other people interested - please leave your note.

Denis,
I agree with weebib. It would be of much help if you add the reload feature.

I have tried you codes.
As you said, only root node is displayed after xml document loaded.
Do you work out the problem? And what jdom version are you using?
I am very insterested in XML tree.

 

 

Sorry, I do not use asksAllowsChildren argument.
I will learn from your codes. Thank you debopamghoshal.
Here is my test codes.

import javax.swing.*;
 
public class XmlTreeDemo extends JPanel {
    public XmlTreeDemo() {
        XMLTreeModel model = new XMLTreeModel("tree.xml", true);
        JTree tree = new JTree(model);
        add(tree);
    }
 
    private static void createAndShowGUI() {
        JFrame frame = new JFrame("XmlTreeDemo");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
 
        XmlTreeDemo newContentPane = new XmlTreeDemo();
        newContentPane.setOpaque(true);
        frame.setContentPane(newContentPane);
 
        frame.pack();
        frame.setVisible(true);
    }
 
    public static void main(String[] args) {
        javax.swing.SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                createAndShowGUI();
            }
        });
    }
}

 

 

debopamghoshal , I tried to use that code on a school project i'm developing, but some functions weren't known...

also, the XML tree presented didn't have the name of the structure nodes, only the data in the XML file.

Can u help me on this ?
