The artifacts in the ArgoUML model may be configured for displaying in the tree by a number of perspectives. To this end, a drop-down at the top allows selection of the explorer perspective.
Below that, there is a drop-down to select the ordering of the atifacts within the hierarchy. The two possibilities are "Order by Type, Name" and "Order by Name". The former groups all items per type, and sorts them per group alphabetically on the name. The lattter simply sorts on name only.
The following explorer perspectives may be selected in the drop-down at the top:
Package-centric (the default). The exploring hierarchy is organized by package hierarchy. The top level shows the model. Under this are all the top level packages in the model and all the artifacts that are directly in the namespace of the model.
Beneath each package are all the artifacts that sit within the namespace of that package, including any further sub-packages (which in turn have their own sub-hierarchies).
Class-centric. Shows classes in their package hierarchy as well as datatypes and use case diagram elements. Similar to the Package-centric view but it doesn’t show connecting or associating elements.
Diagram-centric. In this view the top level comprises all the diagrams in the model. Beneath each diagram is a flat listing of all the artifacts on the diagram. Artifacts that have sub-artifacts that do not appear on the diagram have their own hierarchy (for example attributes and operations of classes).
Inheritance-centric. In this view the top level shows the model. Beneath this are all artifacts that have no generalization in the model. Those artifacts that have specializations have a sub-hierarchy showing the specializations.
Class Associations. In this view the top level shows the model. Beneath this are all diagrams and all classes. All classes that have associations have a hierarchy tracking through the associated classes.
Residence-centric. In this view the model is shown at the top-level, with below it only Nodes, and below these only components that reside on the nodes, and below these components all elements that reside on the components.
State-centric. In this view the top level shows all the state machines and all activity graphics associated with classes.
Beneath each state machine is a hierarchy showing the statechart diagram and all of the states. Beneath each state is a list of the transitions in and out of the state.
Beneath each activity graph is a hierarchy showing the activity diagram and all of the action states. Beneath each action state is a list of the transitions in and out of the action state.
Transitions-centric. This is very similar to State-centric view, but under each state machine is listed the diagrams and all transitions on the diagram, with states being shown as sub-hierarchies under their connected transitions.
Similarly under each activity graph is listed the diagrams and all transitions on the diagram, with action states being shown as sub-hierarchies under their connected transitions.
