Facility Control

Hi, 

I am trying to build a widget that reacts when a parameter on it's device Data Source changes. I have built a simple panel that functions, but when converting it to a widget I am unsure where to put the object ID of the device, and not sure where to put ogscript handles tag. Especially as I also want to pull from the parameter which is an array, but that parameter be selectable on a per widget basis

Is this possible or will I need to create a different trigger for events?

Cheers,

Dan

Hi Dan,

I think this is possible. Below is a similar panel in which the widget selection changes as per the selected parameter and vice-versa. 

In the panel below, we make use of the "onchange" and "onload" handlers. Here, in the first ogscript block, upon loading or changing,  we check the value of "Selection_OID" which is the parameter with the text input and set this value to the Selectable so that whenever we change the value of the Selection_OID, we automatically update the selected constraint. Similarly in the next ogscript block, when we change the selected constraint, we update the Selection_OID accordingly so that both the parameters have the same value. 

In your case, you can use a similar ogscript onload and onchange handler which updates the widget parameters as per the Device's data sources.

I hope this helps! If it doesn't, feel free to reach out and attach the panel if possible.
