Brian's previous response is correct (as usual... ;^) ).
You can't really test the results of the [focus] command interactively
(at least on Windows), as the "console" window must have focus in
order for you to "type". Since the console has focus, your app
doesn't - which means that the [focus] command returns nothing.
When I tested this (before my original response), I had to use [after]
in order to get the expected result from an interactive session.
In a running application, [focus] *will* return exactly what you
want - the name of the *widget* that has focus - if one exists. If
you get nothing back from [focus] in your running application, then
nothing in your application has focus.
I think if you'll just try it out, you'll see that it really does do
*exactly* what you want.
