[news.eclipse.modeling.gmf] Re: What's the best way to implement "ports"

[Enrico Schnepel <enrico.schnepel@xxxxxxxxxxxxx>]

Hello Michael,

ports are created like compartments in the mapping def model, except that
there is no CompartmentMapping referenced in the ChildReference. In your
semantic model: the port element must be a child element of your main
element. This will address your pints 1, 2, 3, 4.2 and 5. For 4.1: This is
controlled by BorderItemLocator creted in the addFixedChild method in the
[MainFigure]EditPart (At least in GMF 2.0... does this have changed???).

Best regards

Enrico
