From the April, 2010 visit, Warren writes: "`Pub/Sub UI Improvements - Add in ability in UI to find all Subscribers to a given Publisher and vice versa."

Probably the best way to do this would be to have a search mechanism that brought up a tree view. It is not clear how much effort a search mechanism would take.

We have "DependencyHighlighter", which should work here:

  1. $PTII/bin/vergil ~/ptII/ptolemy/actor/lib/test/auto/PublisherSubscriber9.xml
  2. Utilities | Analysis
  3. Drag HighlightDependents onto the Publisher
  4. Right click and select "Highlight dependents"

Unfortunately, we get a stack trace:

This is completed:

If you drag a Utilities -> Analysis -> DependencyAnalysis attribute on to an actor, a new menu choice appears: "List dependencies and prereqs."

The underlying code is in actor/util/ActorDependencies.java.

The underlying code is ugly, but it works for finding Publishers and Subscribers.
