There's ede-find-file (C-c . f), but that one doesn't complete.

Emacs has all kinds of completions, though; I prefer ido, so I use:

(defun DE-ido-find-files-in-project ()
  (interactive)
  (let ((allfiles nil)
	choice)
    (ede-map-all-subprojects
     ede-object-root-project
     (lambda (p)
       (let ((targets (oref p targets)))
	 (dolist (target targets)
	   (setq allfiles (append allfiles (oref target source)))))))
    (setq choice
	  (ido-completing-read
	   (format "File in project %s: " (oref ede-object-root-project name))
	   allfiles nil t))
    (when choice
      (ede-find-file choice))))

I guess the snippet which sets 'allfiles' would be a good convenience
function for EDE, so that people can hook it into their favourite
completion engine.
     
You can quickly hack together all kinds of alternatives, though. For
example

(defun DE-ido-find-file-in-proj-dir ()
  (interactive)
  (ido-find-file-in-dir (oref ede-object-root-project directory)))

will call ido with the current project's root directory. Also, have a
look at the recentf package, which lets you quickly find recently opened
files. The EmacsWiki has all kinds of hacks for it:
