The Outliner

The Outliner displays a hierarchical tree representation of the currently active Graph-Document (if any). At the top-level of this structure there are the Edges and Nodes of the Graph. Every Graph element is listed in this Tree-View.

Every top-level entry can be opened up. After unfolding them you can view the details for a Node, respectively Edge. For example, for a Node you might find that it consists of a Rectangle.

This is a basic shape type that can be found in the Repository. For a Edge you might find that it consists of a PolyLine, likewise a basic shape type.

After selecting an element in the Outliner notice that the corresponding element in the GraphView is selected as well. This feature can relieve your work on large Graph-Documents.
