I use the following function to do this:

(defun c++-convert-to-method-body ()
  "Take a function prototype from the class definition and convert it
to the implementation body"
  (interactive)
  (let ((class-name)
        (doit))
    (save-excursion
      (back-to-indentation)
      (setq doit (looking-at ".+(.*); *$")))
    (if doit
        (progn
          (save-excursion
            (re-search-backward "^[^ \t].+\\(\\<\\w+\\>*::\\)")
            (setq class-name (match-string-no-properties 1)))
          (back-to-indentation)
          (when (looking-at "virtual")
            (message class-name)
            (delete-region (match-beginning 0) (match-end 0)))
          (beginning-of-line)
          (re-search-forward "(")
          (re-search-backward "[ \t]")
          ;;(forward-char 1)
          (delete-horizontal-space)
          (insert " ")
          (insert class-name)
          (end-of-line)
          (delete-region (point) (- (point) 1))
          (indent-according-to-mode)
          (insert " {\n\n}\n")
          (next-line 1))
      (message "This line does not contain a valid method declaration"))))


(define-key c++-mode-map [(control c) ?e] 'c++-convert-to-method-body)

Now I copy the function definition from the header file to my cpp file and
hit C-c e.

The function works for most of the method definitions that I use.
