How can I detect if an event is via the User Interface or via a signaling property?

[Michael Aivaliotis]

I'm responding to user interface events using an event structure. However, some of those events are coming from a signaling property node. Is there any way from within the event structure to detect the difference between actual user generated events?

You have probably moved on by now but... I was not able to find anything to distinguish between the two sources. (at first I remebered seeing teh "source" property in am image from Jim's book but it did not distinguish between a human and the value signalling source.

Could you add the mouse and key down events to the value change event case and then look at the event type.

I guess that will not really work, sorry.

You can't do this. However, instead of using Value Signaling property nodes you could use User Events. You can even create a User Event that can be registered in the exact same event case as a Value Change event. The trick is to make the User Event data be a cluster with the exact same event data from the original event type. Then, the Source terminal on the event structure could be used to tell if it was a UI event or User Event.

Attached is an example (LV2010).

More importantly, though, why do you want to know the difference?
