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

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