[news.eclipse.platform.swt] TreeViewer with visible root

["Sarah Ettritch" <respond_to_newsgroup@xxxxxxxxxxx>]

I'm having a problem with TreeViewer when I want the root node of the model 
to be visible (root being the node that doesn't have any parents). Expanding 
the root node always shows the root node as a child. For example, if I 
expand root, I see root, root. If I expand that, I see root, root, root, 
etc.

>From debugging the code, it looks like the structured viewer ultimately 
calls getElements(), rather than getChildren(), when getting children for 
the root. Since I want the root to be visible, getElements() returns root, 
hence the root, root, root, etc. Is there a restriction on TreeViewer that 
the root can't be visible?
