+ * @screen: screen to show the uri on or NULL for the default screen
+ * @uri: the uri to show
+ * @timestamp: a timestamp to prevent focus stealing. 
+ * @error: a #GError that is returned in case of errors
+ *
+ * This is a convenience function for launching the default application to show 
+ * the uri. The uri can amongst others (depending on support in gio/gvfs) take 
+ * the following forms:
+ * "file:///home/gnome/pict.jpg",
+ * "http://www.gnome.org",
+ * "mailto:me@gnome.org",
+ * "ghelp:eog".
+ * Ideally the timestamp is taken from the event triggering gtk_show_uri. 
+ * If timestamp is not known you can take %GDK_CURRENT_TIME
+ *
+ * Returns: %TRUE on success, %FALSE on error.

+ * Since: 2.14
