Re: [eclipse-incubator-e4-dev] The future of e4 SWT for native OS ?

[Kevin McGuire <Kevin_McGuire@xxxxxxxxxx>]

Hi Ivan,

Yes that's correct but just to be clear:
on the desktop for native OS, the API and programming model, including
the event loop, will be maintained.  Fully backwards compatible.

For the e4 support of browser based
technologies, some aspects of the model will change due to the difference
in nature of these as platforms (e.g. lack of threads as Tom expanded on).
 Also some things may no longer make sense, like synchronous/blocking
modify/verify callbacks which would now spread from client to server.  That
said, we're highly motivated to keep things the same as much as possible.

In short, if your focus is desktop native
OS based SWT, then you should rest assured that all will continue as it
has.  If you're interested in browser based technology, then you should
see a high degree of similarity and thus potential for reuse.

Cheers,
Kevin

This is a good news!! Now I understand what Steve tried
to say in that news. I believe he is referring the event loop model which
is 3.x and this event loop model SWT will continue to support for another
5 years more. e4 will use a very different model which might now compatible
with 3.x... right ? I believe this is what Steve tried to say in the news...haha
ok, thanks guys!! At least I know SWT for native OS still go on, just that
will have "a bit"
different model... Is fine for me, as long as it make things better. :-D

Thanks Kevin and Tom
:-D

This is incorrect.  SWT will continue
to support native OS for, well really as long as we can see there being
an SWT.  The need and value of native look and feel will remain as
relevant in 4.0 as it is now.

I will let the SWT guys expand on this
from a technical standpoint. but I wouldn't at all characterize it as a
"very different design".  The easiest mental model is to
simply consider Flex and Silverlight (and RAP for that matter) as new platforms.
 Steve spoke similar words in his presentation.  There will however
be some API and programming model differences, for example Steve mentioned
that running your own event loop won't make sense on the web platforms.

"With all of the buzz around e4, Steve Northover
sought to allay fears about support for the 3.x versions (particularly
3.4, Ganymede). He said that they would not be abandoned, and in fact,
development would continue for about five more years, with many of the
features developed for version 4.0 appearing in 3.x releases."

 It sounds like SWT for native OS will stick on 3.x only... and will not
move forward to version 4.0... If SWT for native OS will still go on...
they will not said like that...Am I correct or.. I miss understand the
statement ?  

 or... e4 will use a very different design than 3.x and e4 not only continue
support SWT for native OS, it also will support AJAX, Flex and 
Silverlight platform ? 

Thanks and sorry guys. :-D_______________________________________________
