Hi David,

The latter.  Here's the e4 summit page, although I'm not sure how much it 
helps:

http://wiki.eclipse.org/E4/DeclarativeUI

What we're looking at is declarative technology as another way to build 
UIs in the Eclipse platform.  At the CSS level, this would be a CSS parser 
to read in the CSS files, likely some SWT support so the styles would be 
applied directly to the widgets on creation, an approach to mapping CSS 
concepts like ID, Class, pseudo class, to Eclipse concepts, understanding 
the role of JFace in all this, etc.  Other related declarative 
technologies worth considering are XForms for building 
wizards/dialogs/editors/etc. although I suspect our plates will be full 
just looking at CSS technology.

This initial effort is really around CSS enabling technologies but other 
declarative approaches are worth considering at this early juncture.

We haven't yet discussed editing environments or tooling.  It'd be great 
if you could at some point present the CSS Editor in WTP.  Perhaps we 
could do it sometime after this first technology evaluation?  That would 
seem to dovetail nicely.

Hope that clarified.  I know its tough keeping up with all the 
conversations.

Cheers,
Kevin

Re: [eclipse-incubator-e4-dev] CSS and declarative UI round up







I realize that me not knowing exactly what you are asking for doesn't bode 
well :)   ... but, what does this encompass? 

CSS Editing? 
or, more a CSS Rendering Runtime? 

If the former, I'd like the CSS Editor in WTP considered and would be 
happy to present., if there's interest. 

Thanks,

[eclipse-incubator-e4-dev] CSS and declarative UI round up





Hi folks, 

Over the course of discussions, many folks have come forth with a favorite 
CSS/ declarative-UI implementation.  So much to choose from!  So much to 
know!  As a first step, I thought it'd be helpful for us to have a roundup 
of them all so we can discuss their pros and cons.  Eventually we'd all 
like to see some working CSS code in e4 eclipse.org repo and at the moment 
it seems the main problem is we have too many to choose from (a great 
problem to have!). 

What I had in mind was: 
Those who have some technology they'd like to bring forth prepare a small 
presentation of its pros and cons. 
We have a call where they are presented.  We can as a group then better 
understand our requirements and which technologies fit those. 
Ideally we would have three presentations of 1/2 hour each (including 
discussion), plus wrap up discussion, so two hours max for the call.  I'd 
prefer a shorter call but I don't think that's realistic.  If we have more 
than three presentations then we can split it into two calls, since I 
don't know about you but my attention span nears zero after 2 hours. 
Our goals should be selecting the technology which will be the initial 
commit for the purpose of investigation.  We may change our minds later, 
but we need to start with something.  If there are two (or more) favorite 
technologies we can commit both, like we have the EMF/non-EMF modelling 
work. 

What do folks think? 

If we like this approach, I'd suggest we aim for a call in approximately 
two weeks, to folks time to prep.
