Read Only - No new appointment.

Hi I was wondering how I can disable the ability for a user to create a new appointment in the calendar. I have set the existing appointments to read only and that works but I don’t want the user to be able to add any new appointments via this particular view. Any ideas?
Adding scheduler.config.readonly = true; then stops the double click event from happening and showing an existing appointment in the detail view.

Thoughts?
Thanks!

scheduler.config.dblclick_create = false; scheduler.config.drag_create = false;
