Sizing nodes wrt ports : just can't get it work [message #1773925]

Hello,

I'm trying to define layout strategies for Sirius diagrams and I just can't get it work.
I want to have a nice distribution of ports (and labels) along my node.
I use the nightly build 0.3 (171006).
Here is the structure of my diagram and the different configurations on the 3 boxes.
I use simpler layout algorithms (BoxLayout or FixedLayout) for nodes that don't have complex structures.

index.php/fa/30929/0/

And here is the result displayed by the Layout view:
index.php/fa/30930/0/

As you can see, ELK tries to distribute the ports on the west side but it doesn't trigger a resize of the node.
I al not sure that the 'Node Size Options' / 'Node Size Constraints' of the node hosting the ports is correctly working.

Note : Things are going slightly different when 'ELK layered' is used instead of 'Bos Layout'.
When I try to explicit a constaint on 'Node Size Constraints' (e.g. PORTS), I've got the following error:
index.php/fa/30931/0/

Is it possible to specify a side from the 'Layout view' through a set of options? Or is it programatic only?

Set aside this issue, with 'ELK layered' or 'Box layout', if I have a correct size for the node (e.g. playing with a laaaarge padding value) , then the algo manages to place the ports according to the other options (i.e. 'Port Spacing', 'Port Alignment'): index.php/fa/30932/0/

Hi Benoit,

as you found out only ELK Layered currently invokes the code that is responsible for resizing nodes based on ports and labels. In a final product, assigning port sides and generally configuring layout appropriately should be done programmatically through a custom layout setup. However, the layout view should allow you to set port options (such as its desired side) upon selecting a port.
