Hi Mike,

Launch the logic example editor (that comes with GEF), throw a few shapes
on the diagram. Switch to "Resource" perspective just in case you're using
some other perspective. There is an "Outline" view in the bottom-left
corner. On the outline view's action bar there is a button with a
tree-like icon on it on far left from minimize and maximize outline view
window buttons. Click on the tree view button and you shall see the tree
view of the diagram it's built using the TreeViewer. An example of the
usage of TreeViewer can be found in logic example's source code. Open up
LogicEditor class, it should have a private OutlinePage class - this class
is the code for the outline view customized by the logic example editor.
Look through it and you'll find how the TreeViewer is used.

Cheers,
Alex
