Hi all

We have built our app on top of RCP because RCP provides us all the
components in the Eclipse platform.

We use:
*the Common Navigator
*Properties view
*Resource management
*Import/Export... the list goes on...

Are these components (re)usable in a plug-in created using e4?

They're not usable in an e4 RCP app. They are usable in an
Compatibility Workbench RCP app, but since the compatibility layer
pretends to be the 3.6 API running on top of the modeled workbench, I'm
not sure what it would buy you (although it would run the CSS theming)

What would you like out of e4 that you don't think is available in 3.6?

So the package explorer that I see in the e4 UI, is that an e4 "navigator"
or is that using the navigator from 3.6 somehow?

I'm trying to figure how much work it would be to migrate an RCP app with
the mentioned features into an e4 app.

Cheers

Greg

Which e4 UI? If you mean the e4 SDK, that's just 3.6 with the
development bundles installed. If you mean the 4.0 Early Adopter SDKs,
that's the 3.6 package explorer being hosted on an e4 modeled workbench
(org.eclipse.ui.workbench).

Right now, 3.x plugins can run using the compatibility layer. But
certain aspects of it don't work well at the moment (menus come to mind).

In the e4 world, you can write dependency injected parts, but there is
not support for the Project Explorer, your menus and commands have to be
written using the model, not the extension points, etc.

As for effort ... you would have to put in a fair bit of effort to move
to the e4 world, or you can run some tests with the compatibility layer
and your 3.6 views/editors/etc.

Ok thanks Paul. Exactly the info I wanted.

Just one other thing - will there ever be a pure e4 project explorer? And if
so, will it be in the next year or so?

Thanks
