Re: [gef-dev] GEF extensibility
|
Hello Eugene,
I read your post in the gef-dev newletter, we would like to develop the
diagramming tool in the Eclipse RCP during the summer / autumn.
Are you able to do it? If yes, we would like to hire you.
Tell me if you are interested and what rate do you like to charge.

You can provide custom implementation for almost anything in the GEF - as
long as it complies with the framework (i.e. mouse input is handled in
tool/drag tracker, model presentation is handled by the edit part, etc.)

Yes. In most cases:
1. You create your edit part factory.
2. You create your palette.
3. Depending on the active tool model is updated, if needed new edit parts
are created (you will supply implementation) and respective edit policies
are created (again - in most cases you will create them)
See GEF examples for details.

GEF does not constraint in your application design - it is just a
presentation framework. You create ordinary Eclipse application and
one/some/all editors use special widget (provided by GEF) to render the
model to the users.
