Diagram layouts [message #840078]

Hi all...

The other thing I've been struggling with is diagram layouts. I have a simple flow-style diagram that shouldn't be too difficult to auto-layout, but haven't seen a good way to implement it.

Is there a better way than hand-coding individual shape locations during the import process?

Thanks again!

You can take a look at graphiti FAQ, it has a topic on this:

http://www.eclipse.org/graphiti/developers/faq.php

By the way, there was recently a discussion on integrating Kieler layout algorithms into Graphiti:

Joao,

Thanks for the link. Already found that and was playing with it but didn't get far. Do you have an example where it works for nested container shapes? I have a diagram with a root container shape that contains several container shapes of its own. And I've mangled the example code to get it to do some very intriguing things with the diagram, but not exactly what I want (i.e. the diagram becomes huge and things get moved and resized quite oddly).

Layouts are definitely not my forte.

And I did find this forum post:

Which offers a way to use a Zest layout, but it doesn't seem to work for my nested diagram approach...

In a layout dialect I think this is called "clusters".
Have a look at graphviz, it may provide the layouter you need.

Interesting... Thanks for the suggestion.
