Hi,
Assume two models A and B each of them in a separate plugin where model
B extends some classes in model A. Also assume that model A has a GMF
editor. Does GMF support the feature of automatically adding the
subclasses in model B to the editor palette of model A?

It seems to me there were two questions:
1. Could you explain more why GMF does not support the feature of
automatically adding the subclasses from extended models found in another
plug-in?
A: Because it was never a requirement to do so. If you would like this
added as an enhancement, please enter a bugzilla. We'd welcome your
contribution on this request as well.
2. If EMF supported this feature, would it affect GMF to automatically add
the children?
A: Perhaps it's best to begin with EMF on this one?
Thanks,
Rich

Rich,
In EMF, we would add support for this via the
ItemProviderAdapter.collectNewChildDescriptors which are used to
populate the popup menus to create children. We'll need some type of
EMF.Edit registry to determine all derived classes including ones
contributed by extending plugins. I'm not sure the GMF editor uses
these though...

Assume a plug-in-based graphical editor with a palette where the users can
develop their own plug-ins and these plug-ins appear as more tools in the
palette. Of course Eclipse is an excellent choice for such an IDE,
however, ironically neither EMF nor GMF do not support this. At the same
time, the plug-in architecture of Eclipse seems to be of no use.

1. Moreover, automatically adding subclasses is definitely not the way to
handle the usecase. There might be few models, and it just wrong to assume
that any other existing model that extends the one with GMF editor should be
automatically picked up. Besides, I'll tell you the next question once we do
it automatically: "Elements from my extended model are shown, though I would
like to have different icon/figure/behavoir/whatever for this particular
element". Hence, even if it's automatic, than you describe it somehow, and I
bet it's better to start with "describe" approach from the very begining.

This usecase is very straightforward to use - declare your own extension
point and modify creation tools to read extensions.

Artem,
So, what is your suggestion for implementing the idea of having a
diagram which the users can develop and add their own items to the
diagram where the items are coded in a different plugin (obviously the
users are not supposed to touch the actual diagram code) and they can
appear in the pallet automatically.

Hi,
GMF Runtime is all about this - contributing extensions to existing
services. Whether these extensions are handwritten or generated is not
important, so you may use GMF to generate code for extended versions and
plug them in using whatever mechanism (existing services framework,
adapters, your own set of extension points or anything else).
My point is, not every application needs every use case one could imagine.
E.g. there are GMF users that don't even want to edit a diagram (just
visualize some domain). Similarly, there might be users that don't want to
get automatic extensions. Hence, if there's a requirement like
> users are not supposed to touch the actual diagram code) and they can
> appear in the pallet automatically.
it's better to think in scope of your application - what would be the best
way to provide extensibility means.

Unfortunately, I don't have such an example.

Artem,
I meant if you could create a very basic example demonstrating this (not
an already available one). At least, some clue where to start the
extension framework? Not too much documentation on GMF Runtime is out there.
