GMF diagram elements movement should affect underlying EMF model [message #494119]

Hi,

I implemented a grid layout for the compartment contents; the behaviour
is as expected, I can drag&drop the nodes within a comparment, and can
reorder them in this way.

Of course, the order within the list of the visual IFigures is not
synchronized with the underlying model; what is a suitable practice to
achieve a reordering on EMF level?

(I want the .model-file to reflect the order that I dragged within the
diagram - so reordering needs to be on model-layer, too)

Do i have to create a specific command for this?

Thanks,
Timothy

This is all related to containments, not compartments, sorry for the typo.

Hello Timothy,

To store some specific layout constraints in EMF you can either create own
subclass of org.eclipse.gmf.runtime.notation.LayoutConstraint (in separate
..ecore model + generate plugin for it) or store this info directly in underlying
domain model properties. In addition you have to modify ???EditPart.refreshChildren()
method to properly handle these constraints..

Another option is to rely on an actual sequence of model children in correspondign
containment feature. Looks like this code is already present in default ???EditPart.refreshChildren()
implementation.
