ports [message #221327]

Hi,
I'm new to GMF, and absolutely know nothing about GEF. My question is: How
to make a shape with some connection points. I mean something similar as
in "logic example" but that is in GEF. I want to have a shape with ports
to which a connection can be added. I want to make target ports occupied
if there is a connection and more connection to be able from source ports.
But in EMF model I want to store it as a collection of connections (so in
EMF I don't care to which port exactly is the connection connected). Is it
possible, with use of GMF?

Thanks

Fero

Hello Frantisek,

It is possible to generate code placing child element from the domain model
onto the border of it's parent. To do that you have to set AffixedParentSide
property in .gmfgraph model.
If you need to create these port only on a diagram without any connection
with domain model elements then you probably have to code it manually.

Hi Alex, thanks for advice I will look at it. But I think you suggest that
port would be in a model as a child of a node. That's not what I want (I
want only connections to be many attribute in my model). It should only be
in graphics representation.

Or maybe I won't use the ports. Is it possible to make a node that all
incoming connections will be routed to the left side and all outgoing
leaving from right side?

Thanks for answers

I think it should be possible by using/implementing appropriate ConnectionAnchor.
See org.eclipse.gmf.runtime.gef.ui.figures.NodeFigure.getConnect ionAnchor()/getConnectionAnchorTerminal()
+ try searching in this neasgroup for the related postings.
