close, but I think the parameter is missing. Here's what I use:

(defun cscope-popup-menu-prompt (event)
  "Handle `mouse' events for cscope. EVENT is the mouse event."
  (interactive "e")
  (popup-menu cscope:menu event))

(defun cscope-popup-menu-no-prompt (event)
  "Handle `mouse' events for cscope. EVENT is the mouse event."
  (interactive "e")
  (let ((cscope-no-mouse-prompts t))
    (popup-menu cscope:menu event)))

(define-key c-mode-map   [H-mouse-1]   'cscope-popup-menu-prompt)
(define-key c-mode-map   [S-H-mouse-1] 'cscope-popup-menu-no-prompt)
(define-key c++-mode-map [H-mouse-1]   'cscope-popup-menu-prompt)
(define-key c++-mode-map [S-H-mouse-1] 'cscope-popup-menu-no-prompt)))


Cheers
