Hi Martin!
So it would be useful to ask the tool things like:
- paint / iterate the nodes such [:object | object class ==
UnexpectedClass]
Having some iterators you mean?
- suggest me a "bottleneck" edge
An iterator could easily do the thing. I will provide the infrastructure.
I inserted visitor. I built a ROHighlighter that highlight some nodes. You can use it like: ROHighlighter for: b in: view. where b is a block.
Look for the users of ROHighlighter to see some examples.
Let me know if you need more.
- show me the shape of the whole graph and I could discover what is
wrong at a glance
Yep, this is on my todo list. Having a small portion of the window that
shows the whole graph.
I still need to work on this.
Cheers, Alexandre

Cool!
Here is a new version of your script:
| view initialNodes | view := ROView new. initialNodes := (ROLabelElement spritesFor: (Array with:Integer)) asOrderedCollection.
initialNodes do: [:n | n + ROLabel. n @ (ROExpandChildrenOnClick newCalculatingChildrenWith:[:aClass | aClass subclasses])].
view addAll: initialNodes. ROTreeLayout on: initialNodes. view @RODraggable @ RODraggableWithVelocity. view open-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
I also fixed a few things in your class: <ROExpandChildrenOnClick.st>
Let me know how it goes.
Cheers, Alexandre

I downloaded Roassal, I like it!
Modifying an example, I obtained something like an expandable tree,
but I don't know how to re-layout after click. Could you help me?
I paste the script and I attach a class (which is needed).
| view initialNodes | view := ROView new. initialNodes := (ROElement spritesFor: (Array with: Integer))
asOrderedCollection.
initialNodes do: [:n | n + ROLabel. n @ (ROExpandChildrenOnClick newCalculatingChildrenWith:
[:aClass | aClass subclasses])].
view addAll: initialNodes. ROTreeLayout on: initialNodes. view open
Thanks! Martín

> I fail to see what these principles are :). Mondrian is nothing but
a very simple graph model with a builder api and some rendering logic. zOrder is just a smart way of drawing edges such that you can see them properly even in the case of nested graphs. But, the model does not have to be static.
Although quite effective visually, the zOrder gives an ordering that
may be different from the one specified by the user.
You could have: view node: 'A' forIt: [ view node: 'B' ]
But the ordering of drawing A and B is driven by the zOrder. The
elements to displayed are cached in the MONode. However, the lookup when you define an edge itself follows the node nesting.
I agree with you that the model that does not have to be static, but
over the year we have put a great deal of effort in making Mondrian fast. Now, we are trying to make it dynamic in addition. This is a non-trivial piece of work.
Also, I have the intuition that we need a dedicated DSL to define
the kind of visualization Martin is looking for.

Thanks!

Mondrian?
I haven't addressed the need for performance. One cool thing about
Roassal, is that I do not rely on the Morph scrollbar. This gives more control about what exactly is displayed. Also, I have flying cameras, which is neat.
> - It is at a lower level of abstraction than Mondrian, but higher
than actual rendering. The first thing I thought of when looking at it was that perhaps it would be interesting to have it as a backend for Mondrian. Like this we can potentially have the best of both worlds and we can reuse the engineering effort. And then I saw ROMondrianViewBuilder which is a good start :).
Ideally, I would like Roassal to be a low level for Mondrian. This
is indeed what I tried with ROMondrianViewBuilder as you can see. I guess that for Martin problem, we need something like ROHierarchicalGraphViewBuilder.
> - I like the decoration. This is what we had in Mondrian, but that
got lost in translation.
Yes! I also would like to have decorators to manage caches. Having caches
within MOGraphElement and its subclasses complexify the whole thing.
> - The rendering logic is tightly coupled with Morphic. It does not
have to be, right?
Is not really tight to Morphic. Classes such as ROLine, ROBox, ROCircle do not directly talk to a
form, but to a ROCanvas instead. I will probably add ROFormCanvas, ROHTML5Canvas in the near future
> - I did not see how the decision of drawing edge appears to be. For
example, in the mondrian2 you have the edges drawn on top of the nodes. But, I am not sure if this is because of the declaration order of because of something else.
The view had an ordered collection of elements, which is
sequentially displayed.
The strategy of displaying edges should not be hardcoded in the
ROView.
Consider the script:
-=-=-=-=-=-=-=-=-=-=-=-= | view | view := ROMondrianViewBuilder new. view nodes: Collection withAllSubclasses. view shape line. view edgesFrom: #superclass. view treeLayout. view open -=-=-=-=-=-=-=-=-=-=-=-=
We could have
... view treeLayout. view moveEdgesToTheBack. view open -=-=-=-=-=-=-=-=-=-=-=-=
Maybe... Not really elegant. But the order should not be hardcoded
