Re: [eclipse-incubator-e4-dev] Fw: Declarative UI roundup?


I was trying to find an XML Schema for XAML.  Is there one?  DOM is very unconstrained so building a DOM that's well-formed XAML seems important...

Are you aware of

It's interesting to see some of the Oslo developments.  It makes you wonder if Microsoft will build a DSL for XAML. :-)
XML continues to strike me as a poor man's excuse for human readable syntax that's primarily driven by a desire to avoid having to write lexers and parsers.  It's great for interchange, but not so great for humans.

Hi Kevin,

The subject is very interesting but I believe that Eclipse E4 have intention to use EMF.
I would like call about TK-UI for declarative UI but TK-UI use DOM and it seems that people prefer EMF than DOM.

I would like just say too, that I'm refactoring TK-UI to use UFace  (where I'm contributing) which propose this project to Eclipse

I think that UFace is very interesting for declarative UI because :

* it provide universal API to render it to SWT, Swing, QT, GWT... (UIElement )
* manage binding with JFace Databinding. So you can bind properties of widget (visible, text...), layout properties (orientation, with...)
  with anything. Into TK-UI it's easy to bind DOM element, attributes with tje UIElement. Each properties (ex : setVisible) notify listeners. 
* manage Databinding with UIForm. It's easy to manage master detail and into TK-UI I'm using to manage Databinding _expression_  Language (like XAML binding epression).

Thanks all who responded to my previous note.  As we did for the styling roundup, it'd be great if people could fill in a bit of information about a proposed technology as prep for us all for a call.

At your earliest convenience, please take a moment to fill in an entry in the following table:

You'll notice a striking resemblance to the styling one we did, about midway down

The idea here is that providing the information shouldn't be laborious on the part of the presenter, but enough for everyone to get started investigating.  We'll then have a bakeoff call, post slides and notes back to the wiki.

We should aim to have the call in a few weeks.

Best Regards,

Declarative UI roundup?

Hi gang,

As you may recall, in August we had a Styling roundup to look at the different available skinning technologies.  While organizing it, we discussed also wanting to do one for declarative UIs.

There was a lot of interest at the time, and there's been lots of discussion on this list lately about different declarative UI technologies/approaches.  I think the Styling one went well so I was wondering if folks wanted to do one for declarative UIs?  See for an idea.

This would involve some people volunteering to do a short presentation on a particular technology, either their own (e.g. XSWT) or one they are familiar with (e.g. XUL).  There'd be some prep in putting a small amount of information on the e4 wiki, then a call with presentations.  The idea is to have some decent content to discuss but not create a big presentation job for folks, so the emphasis would be on short presentations (and also out of the interest of keeping the call to say 1.5 hours which will be a challenge I think).

The goals of the call would include but not be limited to:

1) All getting on the "same page" with respect to the different technology choices available to us.
2) Open discussion of pros/cons of different approaches.
3) What problems we believe it will solve in the e4 context.
4) Hopefully come away with a small number of "most promising" technologies which the community could focus on in e4.

Any interest?  Note that this is community driven content, so "yes" would mean "yes I'll sign up to provide some content".
