External plugins aware of changes in a diagram ? [message #188259]

Hi!

Is there a way to make an external plugin aware of changes in a diagram ?
And, is it possible for an external plugin to manipulate a diagram ?

For example :
if i create a node in diagram or delete it can i make a plugin X handmade
aware of this through listners for example?
Can an external plugin come and create a diagram like when we create an
ecore_diagram from a .ecore file? And how it can be implemented ?

It will be helpfull if someone has an answer (Yes ? no ? Stop asking for
weird things :p ?)

Thanks in advance

Hello Mous,

> aware of this through listners for example?
Sure. You can add listners for any EMF objects. See GraphicalEditPart.activate()
method as an example - all the generated EditParts (subclasses of GraphicalEditPart)
are registered as a listeners for corresponding domain model elements.
In addition EContentAdapter class can be usefull if you'd like to listen
all the EObjects starting from some top-level one.

See generated EcoreInitDiagramFileAction.
