Yes, I was looking at those.
XAML is just a XML-based format for serialized WPF/.NET objects tree...
It seems folks are quite focused on this XML aspect though with talk of
DOM and XML editors that center around a source view of that XML...
So
MS's defines WPF model in EMF-friendly OO fashion (XamlType)
Hehehe. I see. Defining it in a more formal notation is always kind of
nice too, but I could imagine mapping this to UML or Ecore to produce
an abstract model...
instead of using any W3C stuff...
Ptewy. :-P
Regarding Oslo and XAML, guys please realize that XAML is just a
serialization format.
I suppose I was pushing a bit on exactly that point. A focus on the
XML might well miss the abstract model forest for all the concrete
syntax trees.
If
Oslo would be helpful for developing DSLs for WPF, XAML may become
obsolete and WPF objects will be authored with that DSL.
Go Oslo go!
XAML in fact is nothing more than say XMI.
Ptewy. :-P
Another important thing is XAML is not supposed to be first-class
launguage for UI development, like no one seriously thinking to use XMI
for EMF-based models authoring.
That all certainly fits my abstract view of the world. Thanks for the
insights!
Kind Regards,
Andrey

Angelo,
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 http://www.eclipse.org/proposals/sldt/?
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.
Cheers,
Ed

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
http://wiki.eclipse.org/Eclipse/Incubator/UFacekit
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: http://wiki.eclipse.org/E4/DeclarativeUI/Declarative_Construction_Roundup
You'll notice a striking
resemblance
to the styling one we did, about midway down http://wiki.eclipse.org/E4/DeclarativeUI/Styling_Roundup.
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,
Kevin

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?
Seehttp://wiki.eclipse.org/E4/DeclarativeUI/Styling_Roundup
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".
Regards,
Kevin
