Trigger Datatype Documentation 
Author Message
Reply with quote
i am looking to get documentation/Samples on how to use the Trigger Datatype as an input pin and an output pin.

A normal parameter pin for example can be enumerated in OnChangedParameter.

How is the trigger pin enumerated, say i have 5 trigger input pins, if an event happens i assume it requests an execute activation, how do i tell which pin caused the activation?

If i have an output pin of trigger datatype how to cause the event to fire.

A normal int output pin i would call SetValue() etc

I have quickly reviewed the EyesWeb reference manual but didn't find any methods i could use with the trigger datatype input pins and output pins.

the trigger datatype can be enumerated in the OnChangedParameter method as all the other datatypes. However, you cannot use the GetValue method as the triggers do not have any value.
Similarly, for the outputs, you just need to invoke the SetCreationTime metod.
