;;test like:
;; cd /path/to/xwidgets-emacs-dir
;; make   all&&  src/emacs -q --eval "(progn (load \"`pwd`/lisp/xwidget-test.el\") (xwidget-demo-basic))"


;; you should see:
;; - a gtk button
;; - a gtk toggle button
;; - a gtk slider button
;; - an xembed window(using gtk_socket) showing another emacs instance
;; - an xembed window(using gtk_socket) showing an uzbl web browser if its installed

;;the widgets will move when you type in the buffer. good!

;;there will be redrawing issues when widgets change rows, etc. bad!

;;its currently difficult to give kbd focus to the xembedded emacs,
;;but try evaling the following:
