Hi everyone,

I'm trying to make a button visible only when there is an active alarm, and I'm using the `system.alarm.queryStatus` method for this. However, I'm having trouble getting the `Visible` property to recognize the expression. Is there another way to do this? I just want the button to be visible while there is an active alarm with a specific filter, for example:

if system.alarm.queryStatus(state=['Active'], displayPath="\*BESS\_1\_1\_1\_1 : \*"):  
event.source.visible = True  
else:  
event.source.visible = False

Best regards.

What you're using seems to be a **Script** , you can test it on the console and with some prints you might be able to see if it's working, if it works on the console, then you might have a problem that the trigger you've set your script to might not be working, for example, if you placed it on a mouseClicked event and there isn't a click happening on the component.  
Anyway, try adding a expression binding to the Visible property and use the **isAlarmActive()** function.

Also, is it vision or perspective?

I was actually trying to do it through a script, but what I meant to ask was if there is a way to achieve the same thing using an expression. Sorry if I didn't explain myself clearly enough earlier.

and yees it's Vision properties that I'm working on.

On the other hand, isAlarmActive is exactly what I was looking for, in fact, the isAlarmActiveFiltered() method is even more useful for me. I really appreciate your response, greetings.
