LayoutProvider? LayoutManager? [message #522603]

Hello GMF-List !

I'm currently working on a automated transformation from one EMF Model
to another, which is working pretty good up to now. I also generated a
GMF Editor for both models, but now i have the problem, that the
generated model (a bunch of graphs) is one ugly bulk in the generated
diagram. So i'm trying to implement a layout algorithm for the generated
diagram.

What is the favourite way to control the layout of the elements during
the initialization of the diagram? I already read about
LayoutNodeProvider, but i also found the LayoutManager (which seems to
be more Draw2D?)
It seems that the layout() Methods of both classes are called, if a
element is created or rearranged? I dont't understand the connection
between those 2 classes. What it be enough to implement a new
LayoutProvider with a high priority? Or do i have to change the Manager,
too?
