Hey Marko,
The navigator uses a treeviewer. If you are not familiar with tree viewers
have a look here first
http://www.eclipse.org/articles/treeviewer-cg/TreeViewerArti cle.htm
The treeviewer can display a hierarchical structure using a content
provider. The input model for the navigator view is an instance of
IWorkspace.
For your case: If you want to display a folder structure that is located
in your workspace you can use the eclipse resource model as input model.
You would feed your treeviewer with the IResource you want to start from
(the folder or project). Your content provider would need to know how to
retrieve the children of a folder or project. Thats all.
If the folder structure you want to display is not located in your
workspace (or not part of it). You would have to build up a model yourself
containing the folder structure and than implement a content provider that
can handle that model.
If you still want to have a look at the navigator implementation look at
org.eclipse.ui.views.navigator.
Hope that helps.
