Container layout problem [message #185513]

I am trying to solve a layout problem.I have a model with 2 different
types of nodes. say Node A and Node B. Node A can contain 0 or more nodes
(of type A or B). And this hierarchy can grow recursively.
I want to design something which will lay out the nodes one below the
other without any connection between the nodes with indentation when ever
a node of type A is encountered.
e.g.
|--------------|
|Node A |
|--------------|
| Node B |
| ------------ |
| |Node A | |
| |----------| |
| | Node B | |
| | Node B | |
| | ... | |
| ------------ |
| Node B |
| ... |
|--------------|

Node of type A has compartment which contain all its children.

The "Top Node" and "Child node" etc are NOT labels, but actual figures.

Is there any way to acheive this?
Also when I load a model from file, is there any way to show the
compartments of Node A collapsed by default?

Have you tried ListLayout yet? You can set a Compartment to use
ListLayout in the gmfgen-file. Concerning the Indentation, you could
simply add a fixed-size margin to the left side of both Node A's and B's
figure.

Thanks Tobias,
That helps quite a lot.
I still cant figure out how to set margins in Figure?

I am newbie in GMF/GEF and trying to learn stuff slowly.

Thanks again.

Hello Abhijit,

in the GmfGraph-model you can add a margin border with insets as a child
to the given figure. Alternatively, you can simply add a MarginBorder to
the generated class (in this case you should mark the respective methods
as @generated NOT).
