You can use other predicates to distinguish, something like this:

(defun test-event ()
  (interactive)
  (let ((next (read-event "Enter event")))
  ;;   (describe-variable 'next)           ;; for debug
       (if (listp next)
           (message "Real event (mouse)")
           (if (numberp next)
               (message "Real char read")
               (message "Key press (non char) read")))))

Ehud.
