Finding the answer involves a good deal of tracking
through the on-line docs:

In the on-line help, you have to click on the
"Event listeners" which will take you to a list
of listeners.  Click on "selection".  That takes
you to where you can click on "borland.jbcl.model.
VectorSelectionListener" link.  That takes you
to a discussion of the VectorSelectionListener
interface.  Page down once to see the methods
defined:  selectionChanged, etc.

You want to read about selectionChanged.
Then, you want to read about "VectorSelectionEvent"
which will give you the info on how you get 
which item was selected (i.e., either the "location"
for single item selection, or the "selection"
property for multiple-item selection).  In the
case of multiple-selection, you have to follow
the link to "VectorSelection".  Read about "getAll()".

Then, after that, go back to the designer, 
focus the "Events" tab, and double- or triple-
click on the "selectionChanged" line.  That
will create the method, and you can fill it
in with your newly gained knowledge from the
docs.

Incidentally, this is a question better suited
for the JBCL group.
