Hi Mathieu,
Your force based layout is now in Roassal.
In your test ROQuadTreeTest, there is a method #wellCreated: What is it for? Do we need
it?
I have moved the old ROForceBasedLayout in a dedicated package, called with the sweet name
RoassalOLDForceBasedLayout.
I have also removed your ROElement>>position: . An element should be moved around
using translateTo:
Cheers,
Alexandre

Excellent!
Could you publish the video somewhere so that we can advertise it?

Matthieu, you have done an impressive piece of
work.
I played a bit with it. Check out this cool video (athens based :-)

I slightly modified the following method, by adding a "super step" :
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
ROForceBasedLayout_N>>step
"run a step of the force layout algorithm"
| from to fp tp x y len k quad old |
super step. "<<<<<<< line to add"
edges do: [ :e |
from := e from. fp := from position.
to := e to. tp := to position.
...
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
Execute the following script, drag element and click on it:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
"Preambule. It includes the initialization. "
| rawView view layout |
rawView := ROView new.
view := ROMondrianViewBuilder view: rawView.
"enter your script below"

view interaction on: ROMouseClick do: [ :event |
layout := ROForceBasedLayout_N new.
layout fix: event element at: event element position.

view applyLayout ].
view shape rectangle size: 10.
view nodes: (Collection withAllSubclasses).
view edgesFrom: #superclass.
layout := ROForceBasedLayout_N new.
layout fix: (view nodes last) at: 450@450;

view layout: layout.

Good job Mathieu! Continue!

https://www.iam.unibe.ch/mailman/listinfo/moose-dev Hello
I've added new features for the force based layout.
You can change the gravity center, tell where you want to see your fixed nodes and so
on.
I still have a bug with padding, and resizeStrategy, for example when you click on
Example in the view.
Gofer it
