In XSD editor, it has 1 is text view, 1 is tree view for the XSD model.
My assumption is there is just 1 model but there are 2 ways to edit it, 1
uses text editor, 1 uses tree editor.
I am wondering how the tree view in the XSD editor is construct?
Does it loop thru the whole model about build a SWT tree to represent the
whole model?
Or it just builds the tree dynamically (i.e. when the user clicks on a node
to expand, it just looks up its children dynamically and insert child tree
item to the parent SWT tree item dynamically?
I am trying to do a plugin which has 2 views: 1 is text view and 2 is tree
view. It is used to edit a XML DOM. So I am wonder should I bulid a full
blown SWT TREE for each node in the DOM, or just insert nodes to the SWT
Tree dynamically.
I look thru the code, but I don't really find the anwser to my question.
Any help is appreciated.

Oro,
The tree view is constructed on the fly using EMF.Edit's item providers. Have
a look at the EMF documentation:
http://dev.eclipse.org/viewcvs/indextools.cgi/%7Echeckout%7E /emf-home/docs/doc.html
This one specifically deals with how views are populated:
http://dev.eclipse.org/viewcvs/indextools.cgi/%7Echeckout%7E /emf-home/docs/EMF.Edit_Framework.html
If you use JFace's TreeViewers and its ContentProviders its quite easy to
construct the tree on the fly.
