By inspiring this patch provided by Eric, I have added the fade transition
in e4 contact demo for XWT. The fade transition is added in two areas:
1.
Theme switch
When you change the Theme by Menu, the entire window is animated
2.
Contact selection.
When you select a contact, the detail content view part is animated.
Definitively, the animation is very import feature to develop an
application with fashion UI.
Last week, I was invited by a Defense industry company. They want
to innovate their UI framework. Here is an example of the UI they look for:
http://s3.amazonaws.com/vertigo/FamilyShowOverview-broadband.wmv
which is developed in XAML/WPF. They are looking for a
solution similar for Java.
During this meeting, they have expressed the strong interest on e4
and XWT, and they require the animation support as well.
In XWT, we have started to work on Dynamic UI. The first feature
will be “trigger”:
1. UI Property
trigger
2. UI Event
trigger
3. Data
trigger.
I have created a bug on this topic:

Thanks
Remy...here's an updated patch that explicitly checks whether the system
supports 'advanced graphics' (ie.. setAlpha). While this won't fade on Fluxbox
it shouldn't hang you up either...
<Chatzilla
wit Remy determines that 'Fluxbox' needs even more help...;->
Here's a patch
that should at least run without hanging on any box. Whether or not you see the
fade effect will depend on whether 'setAlpha' works or not...YMMV (which is why
I'm posting the patch)

Note that if you use a Linux/gtk+ build and your window manager
doesn't support compositing (I use Fluxbox), you will be stuck in an
infinite loop because getAlpha() will always return 255. :)
