Could someone tell me the easiest way to detect that a table has been changed (by being redrawn for instance, or by copying new data inside it)? What a pitty there's no kind of event system for this in which you can add and remove handlers for events, or is there?

D.

As far as I know, there isn't. And I agree, it sucks. If you're willing to deal with data structure arrays, you can detect mouse interaction. The [struct] object will output a "click pointer" message when the array is clicked. It doesn't give you mouse-up, though, so you'd have to use it in conjunction with something like [MouseState] for that.

Ok, thx mmb for the info. But since i'm not really looking forward to delve into datastructures (gave it a shot once but found it too complicated for what it can do) would you know if there's an object to quickly sum all values in a table. This would not be 100% accurate to detect all changes, but probably good enough for what i'm trying to do.

[iem_tab/tab_sum] is probably the fastest way to do it in Pd-extended. All those are iem_tab objects are pretty fast, actually--much faster than using [until]. Worth a look.
