I need to set the status of an action based every time an editor is
selected.
My thought was to create a viewer contribution in ui.popupMenus where that
contribution is an IEditorActionDelegate.
I guessed that setActiveEditor would be called every time an editor is
selected. It is called when an editor is first opened up ... but not when
switching between two editors that are already opened.
Was wondering ... anyone know how can I hook into an editor being selected?

Hmmm ... apologize for being ambigious.
By selected I mean ... if there were two editors tabs currently in eclipse,
seleting here means clicking on a tab. So for example, if there were two
editors, Editor1 and Editor2, if I clicked on the Editor1 tab, I am
selecting it. (Is that the same as activating?)
So, now, if I were to repeateadly click the Editor1 tab followed by the
Editor2 tab, I am interested in having my any of my IEditorActionDelegate's
methods to be called (either selectionChanged or activeEditor.)
According to your note, it seems that my some of my Action's methods should
be called since it is a subclass of ActionDelegate ... but I just verified
that they aren't ;-(
To veify, in my Action, I put a breakpoint in selectionChanged and
setActiveEditor methods. They are called initially, but at some point in
time, I can switch between the two editors, and no breakpoints are hit ...
or did I totally screw this up?

Yes. The active part (view or editor) is the one with the blue tite bar/tab.

It depends how you registered the delegate: if you did this via XML then
selectionChagend(...) should be called (if not it's a bug). If you
created the action in code then it is your responsibility to register
them as selection dependent actions. The following links might help:
- TextEditorAction
- RetargetTextEditorAction
- AbstractTextEditor.markAsSelectionDependentAction()

The action was registered via XML ...
