Move It!

Posted by chet on October 23, 2007 at 7:41 AM PDT

Introducing Animated Transitions,
a new library for the easy creation of animated segues between application states.

It's been a long slog, from initial demos of the technology in a session
on "Advanced 2D" at JavaOne 2005, to use of an early version of the library
in the Aerith application, to finishing
off the library and creating more demos exercising it for the book

Filthy Rich Clients
, to getting legal approval for pushing the actual
source code (an exercise over the last several months that was
not unlike slamming the refrigerator door on my head, over and over. Every day.).

But it's finally done, and the long-awaited day is finally here:

The Animated Transitions library is hereby released

The project is available on at
with a BSD license.

The library is fully described in Chapter 18 of
Filthy Rich Clients
. That chapter includes a complete description of the
library's API, detailed explanations of two sample applications that use
the library, and some nitty-gritty details on how the library internals work.

But because there are probably a couple of people left on the planet that
do not yet have a copy of the book (no idea how this happened. Maybe it's
because we have been so
quiet about it. We should really talk more about it), and because I'm
such a nice guy and all, I wrote up a short tutorial on the basics
of using the library, along with a new demo that shows the basics in
action. You can find that tutorial in the article,

"Create Moving Experiences with Animated Transitions"

In fact, here's a web-started version of the demo so that you can see it
in action. Click on the handy image below and run
it. Click on the More/Less buttons to see what it's all about.
Note: There are some artifacts reported on the Mac, perhaps related
to the way they treat layout and the panels that contain the buttons.


Play around with it. Check out the

article and the accompanying demo
. Check out the
demos on the book's website.
Write your own demos. Or, even better, use the
library in your actual applications. Make those applications more dynamic
and help your users actually understand the interfaces they're beset with.

Go on: Move it!
