Rails spinoffs - Mar 2007 - Trying to develop a web graphical editor

Im trying to something like a class diagram graphical editor.

At the begining the problem was making draggables, but the real
problem i have is to draw lines and capture events like drag and drop
a single node of the line or use the line more like an object in
general.

Has some one solved a similar problem?

Thx in advance

I built a proof-of-concept to play with lines connecting draggables. I
got it to the point where you could grab boxes and put them inside
container boxes, save the drawing as XML and reload it from XML, but I
lost the source code.

Here''s an earlier version that you can feel free to do whatever you
want with. The newer one was a lot more object-oriented but at least
this will give you a good start. You can resize the boxes by dragging
the corners. You can click on the boxed to edit their contents.

Radical! Can you add it to a tumblelog, like to make a collaborative mind map?

And what do its unit tests look like?

I would have liked to see the more-complete ver.
I think it has applications for building a social network relationship
diagram too - i was contemplating that but couldnt quite wrap my head around
how to attach and track/move the links when objects were moved.

Another followup. The last time I did this project (I cheated and used
TkCanvas, instead of our endlessly convoluted Ajax landscape), I used
GraphViz for the geometry manager. That means, after the user declares
nodes and connections, I submit them as text to GraphViz, and it
determines the layout, using an industrial-strength and very
customizable constraint engine. Then it returns a raw geometry, and I
snap everything to its coordinates.

Here''s an example using SVG as the intermediate layer:

http://wiki.rubygarden.org/Ruby/page/show/SvgCanvas

If you follow that, the links are kind''a old, so if anything broke
I''ll refresh it. But there are better versions of SvgCanvas on my
desktop(s).

Sorry - I didn''t mean I was looking for a mindmap (but when I do I will
come
right here first). I challenged the OP to set a tumblelog / mindmap hybrid 
as a goal, to see where he can take his project.
