HTMLTreeElement

java.lang.Object
- com.ibm.as400.util.html.HTMLTreeElement

All Implemented Interfaces:

HTMLTagElement, java.io.Serializable

Direct Known Subclasses:

FileTreeElement
```
public class HTMLTreeElement
extends java.lang.Object
implements HTMLTagElement, java.io.Serializable
```
The HTMLTreeElement class represents an hierarchial element within an HTMLTree or other HTMLTreeElements.
This example creates an HTMLTreeElement object.
```
  // Create parent HTMLTreeElement.
  HTMLTreeElement parentElement = new HTMLTreeElement();
  parentElement.setTextUrl(new HTMLHyperlink("http://myWebPage", "My Web Page"));
  
  // Create HTMLTreeElement Child.
  HTMLTreeElement childElement = new HTMLTreeElement();
  childElement.setTextUrl(new HTMLHyperlink("http://anotherWebPage", "Another Web Page"));
  parentElement.addElement(childElement);
  

  
```
Once the elements are added to an HTMLTree object and the elements are expanded, the HTMLTreeElements will look like this:

- My Web Page

- Another Web Page

HTMLTreeElement objects generate the following events:
- ElementEvent - The events fired are:
  - elementAdded
  - elementRemoved
- PropertyChangeEvent
