Hi folks,
I have two model types in my my application. Most of my graphical stuff
has a base class that allows normal graphical interaction, and some of
my graphical objects contain text. I'm adapting the GEF Text sample
code to create the model for my text, but I don't think it should have
the same base class as the rest of the model -- it behaves differently,
especially in its selection and movement.
getModelChildren should return an object of the same base type as the
parent. Is it possible to have a sub-model on the GEF canvas that
manages itself within the space of an object from the larger model?
Thanks,
Fred

each model gets wrapped by an editpart by using your editpart factory of
the editor its being added to. So it does not matter what type of
models you have, so long as you create an appropriate EditPart for each
of them.
You can have children that have children that have children. Nothing
wrong with that. But typically the parent will handle the layout of its
children. And still they are all passed through the edit part factory
of your EditorPart.

Got it, it works now. I just overrode the Part's getModelChildren method.
Thanks,
