[news.eclipse.modeling.gmf] Custom Layout: Spread nodes like a tree to p

[Uwe Südbeck <uwe.suedbeck@xxxxxxxx>]

I wonder how it is possible to Layout my Objects in a Tree like this:

abc---------ab------a----bb----cc
                |      |
abc---------ab --      --bb----cd
          |     |      |    |
abc-------|     |      |    ---ce
                |      |
abc---------ab--       --bb

Please note that in this drawing 'a' is my first component and all the 
others are first level components too but connected to the first 
component. So it spreads like a tree to both sides.

Now i wonder how i can arrange these components to preserve clarity by a 
LayoutProvider. It only works with ILayoutNode-Objects having the bounds 
of the Node but no information about to whom it is connected or not.

Thx in advance, uwe
