Value change event, can be it be set to trigger only when the USER changes the value?

Solved!
Go to solution

The structure i have set up is this, i have a control in which the user chooses a value, when they choose this value, the value change event takes place setting their value in the device. I am then reading back from the device values, and displaying them in this control via a property node.


My problem is that each time i read back a new value into the control, it takes this as a value change event and resets the value within the device, is it possible to make the event only take place when the user themself changes the value?

The value change event should only fire when the user changes the value, programatic seting or writing to a local should not fire an event unless you are using value (signaling) to update the control.  Am I misunderstanding the question?

Yes!

 

My thoughts are that you are using Value (signaling) property node to display to the control. That will trigger another event call.

Use the NON signaling Value property node or a local varible.

 

Post your code if this is not the case so we can help you figure out what is going on.
