Tree nodes in the Dependency Viewer are named according to the study
names of the corresponding objects.
-Non-published objects are shown in the tree as "unpublished" and are

-The long name of the object is displayed in a shortened version;

+All nodes have the fixed size, so the long names are cut and shown
