Is there one? DOM is very unconstrained so building a DOM that's
well-formed XAML seems important...
XAML maps with programming language. The
schema of XAML file is the schema of the associated classes. From this point of
view, it is almost similar to EMF. But the syntax and mechanism is little
different.
For example, if you define a class MyControl
in the package ui,
package
ui;
public
class MyControl extends Control {
protected
String name;
public
String getName() {
return
name;
}
public
void setName(String value) {
name
= value;
}
}
You can map it in XAML directly:
<Canvas
xmlns:ui="clr-namespace:ui">
<ui:MyControl name=”myName”/>
</Canvas>
XSD makes sense for a specific library.

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
