Dear list,

First of all i'd like to say that i'm very impressed by the potential of data structures in Pd. I've always kind of ignored this feature and it's a pity because it's really worth diving into it.

That being said I think that help and example patches are far from sufficient for beginners, and if it wasn't for Chris McCormick's s-abstractions I would have been able to really figure out how to use them (stuff like how to make an entire polygon draggable, how to use GOP with proper scaling, etc.).

It's not just the documentation, it's the interface. Having to walk linked-lists of graphically unlinked objects is bad. Having to use boilerplate to find the head of a glist just to create a scalar is bad.

I think Pd-l2ork is getting close to a release with my new data structure stuff in it. It's a first step at addressing some of these issues.

I m now stuck with a question. How can I identify the element which was just clicked ? I know that [struc] outputs the events, like click, selection and change, but I thought I could identify individual elements by their pointer id. It turns out that I get the same pointer for every element, although I created them sequentially (using [append]).

(I guess something must be escaping me about pointers... I've noticed that within the same template, I get different pointers for elements on different y-levels, but the same pointer for all the element on the same y-level regardless of their x.)

Cheers,

Pierre
