Hallo,
I am new to GEF and want to represent an xml-file as a tree with GEF. Should I create a model or is it possible to do it directly like, say, it is in swing?

Are there examples for it?

Hi Shabaltas,

You can use a JFaces TreeViewer or a GEF TreeViewer.

To use the second one, you have to use the duo Model-EditPart, and
Policies to do action in the widget created !!

If you use the first one, you can do it without a model !!!

With GEF :

public class MyTreeEditor extends GraphicalEditorWithPalette {

public void createPartControl(Composite parent) {
gefTreeViewer = new TreeViewer();
gefTreeViewer.createControl(sf);
gefTreeViewer.setEditDomain(getEditDomain());
//The factory who create the edipart in relation of the model to
use !!
gefTreeViewer.setEditPartFactory(editPartFactory);
...
}

With JFaces :

viewer = new TreeViewer();
viewer.setUseHashlookup(true);

XmlEditorContentProvider xmlProvider = new
XmlEditorContentProvider();
viewer.setContentProvider(xmlProvider);

XmlEditorLabelProvider labelProvider = new XmlEditorLabelProvider();
viewer.setLabelProvider(labelProvider);

MyNode root = new MyNode("root");
MyNode fils = new MyNode("titi");
MyNode fils2 = new MyNode("tutu");
fils.addChild(new MyNode("test"));
fils.addChild(fils2);
root.addChild(fils);

viewer.setInput(root);

Have fun

Bruno
