Try this:
(defun emacs-window-has-focus ()
(interactive) ; interactive to test, with the line below...
(sleep-for 3) ; ...so you have time to change the window
(let ((focused-window-pid
(string-to-number
(shell-command-to-string
"wmctrl -l -p | grep `xprop -root _NET_ACTIVE_WINDOW | cut -d x -f 2` | cut -d ' ' -f 4")
)))
(message (if (= (emacs-pid) focused-window-pid) "has" "not so")) ))
