Look in the Motif man page for the widget you want to add a callback to. In
this case you probably want to do:

	XtAddCallback (boxes[i], XmNactivateCallback, Station, 0) ;

or something like that (the operative change here is XmNactivateCallback).
You don't specify XtNcallback since that resource doesn't usually exist
for motif widgets. The man page will list all of the types of callbacks,
what is passed to the callbacks/etc.
