hmmm, a setable receive symbols for arrays could be interesting. I see the message it gets is just a 'bang' whenever there is a click, but being able to retrieve the index and value of the changed element in a receive symbol seems like a nice thing to have. Though I have lived without this just fine and I'm not really sure about the use cases.

I had kind of a use case for this, but I realized that what I wanted was a multislider GUI, so I made one that just works nicely as one. Using arrays as a hack for multislider is a problem for me because I didn't want just the 'jump on click' behaviour.

So I'm not sure about just requesting this functionality on its own, now that I have my 'true' multislider. I'd go for it if we could also expand arrays and also add a 'steady on click' mode, and also a 'bar visualization mode'... but then maybe that's adding too many things just so arrays work like something else.

Nonetheless, maybe just adding this functionality on its own could indeed be a good thing.

One way to always 'poll' the values, of course, is with [tabread~], and it works at signal rate

cheers

Perhaps vanilla could port the pd-l2ork's <arrayname>_changed send that is attached to each array and is used in conjunction with the global presetting mechamism (preset_hub and preser_node objects). IIRC, canvas hosting the array should also trigger the "clicked" event.

Subject: [PD] "Click" and "Change" Notifications for Array Elements in Data Structures
 
Hello,

I've noticed that while structures in Pure Data usually can send "click" and "change" notifications when modified, this behavior doesn't seem to apply to the elements of an array within these structures (apart from polling solutions like using [metro]).

How difficult would it be to change this behavior in the future, or would Pure Data's architecture not easily allow for it?

Best regards,

Pierpaolo Barbiero
