EVE2 38G update widgets

Post by ACME »

Hello,
I am just getting used to my new EVE2 display. A great thing!
I want to use widgets. Works fine so far.
To display data dynamically using the widgets, I would like to overwrite only the registers with "value", and not send the whole DisplayList every time.
Is there any way to overwrite only the value of the Gauge or Progress widget without sending the whole DislpayList?
Is it possible to make the rest of the display "static"?
If you try to send only the Gauge with the new values, the rest of the display will be deleted.

Thanx,
Markus
