The short answer is "yes, well it depends" :-)
A pure e4 app currently supports all of the layout you'd expect (windows
with sash containers, stacks, and parts). It supports commands,
handlers, menus, toolbars, and keybindings. There's a lot of Dependency
Injection and dynamic invocation. It supports the new CSS styling as an
integrated part of the app.
But if you want access to some of the traditional RCP support, (like
Help, editor and view management, text editors, resource views,
preference and properties dialogs) they're not available in a pure e4
layer yet.

Down this route, there are 2 options:
1) write a 3.x RCP app and use the compatibility layer to run in (off of
Eclipse 4.1). One thing you can do in preparation is only use commands,
handlers, and menu contributions (no actionSets, objectContributions, etc).
2) write a 3.x RCP app, using e4 structures where you can and the e4
"forward bridge" which will host an e4 view in a 3.x based workbench.
Good luck,
PW

I read this a couple of times by now, but it was never said when this might be available. I also didn't find any plans on the web-page of e4 either. 4.2? ... 4.3? ...
I got to like this e4, so it is sad we have to wait one (or more) years for it.

Hi Karl & Kevin,
I can to some extend understand your fustration but I don't agree with
the conclusion you are drawing. The Eclipse 4 Application Platform
provides you the foundation to build whatever you want.
Take a look out the Simple-IDE (found in CVS) it shows how you can
implement a simple resource navigator and editors (e.g. for Java and
XML) solely using e4 technologies.
One of my plan items for Eclipse 4.2 is to refactor certain parts of the
old platform code (UI-Dialogs, Common Navigator, Console View, ...) so
that they work in a pure e4 environment and integrate them using the e4
bridge.
In 4.1 our main target was to get a rocked solid compat layer so that
all 3.x plugins are still functional in 4.1 and I expect more work will
happen on the Eclipse 4 Application Platform in 4.2 once more.
Eclipse 4 Application Platform provides you with:
* Workbench Model (including Parts)
* DI
There's nothing else it provides at the moment! I've started porting
some of the generic UI-Dialogs while working on the SimpleIDE but they
are not fully functional.
Beside that: If you need a feature in your RCP application not available
come and port it! What I really can't understand is that so many people
put them self in passive operation mode when it comes to OpenSource in
general - that's exactly what open source tried to address.
To get out of this passive mode. Would you like to start such a
wiki-page and collect things you as the RCP expert would like to make
use of and people like me and others can go there and leave informations
e.g. of partial implemented stuff, ... or create bugzillas where we
start providing patches.
