I'm trying to draw diagram that contains a single entity which holds multiple elements inside.
My MVC structure looks something like this:
Model: contains EntityModel.java and ElementModel.java which represents my model objects.
View: EntityFigure.java and ElementFigure.java
Controller: EntityEditPart.java and ElementEditPart.java
I'm overriding getModelChildren() in EntityEditPart.java to return list of ElementModel.java so that is how GEF knows that an element "belongs" to an entity.
Since I would like to calculate my entity's figure size and include the embedded elements in this calculation, I cannot call entityFigure.getPreferredSize() during createFigure() in EntityEditPart.java since at this point - the elements figures do not exists (createFigure() in ElementEditPart.java is not invoked yet).
I'm looking for a place to set my entity figure after all child figures were created.
I though about overriding addNotify() in ElementEditPart.java, however, it is being called after creating a specific inner element and not after all elements created.
Any ideas?
Hope I was clear enough...
