Also, in general, there's a good reason for this behavior. If events were to fire on programmatic changes, then you'd have ALL SORTS of infinite loops triggered when responding to input events, each one of which would require you to set some flag before changing a control's state, so that the event handler for that event would know *not* to propagate changes.
It would be an absolute nightmare to code to begin with, and even worse to maintain...
