[news.eclipse.modeling.gmf] Re: Nested Rectangles and Layout

[me@xxxxxxx (exquisitus)]

hello Artem,

Of course this is just a simple example that highlights my problem, not 
really useful by itself.

What I want to do, is to add next nested elements inside Box2 (but this 
time on user demand - not on creation). And for that Box2 needs to be a 
Node so that I can map a ChildReference in .gmfmap.

Your suggestion to use intermediate compartments is exactly what I'm doing 
now! And that works fine, using just Nodes was an alternative solution 
that I wanted to try. The problem with using Compartments is that by 
default they only support XYLayout and ListLayout with 1 column. I need 
other Layouts (preferably GridLayout).

Here's a picture:

I know, not your typical UML diagram :)

Unfortunately I can't see your attachments (I'm using the Web interface to 
read this newsgroup and all I get is a column of text characters...). I 
appreciate your help though.
