In his latest post at Pushing Pixels, Kirill Grouchnikov talks about what's New in Trident 1.2. The Trident animation library has as its objective providing "a powerful and extensible animation library for Java applications." The library is available under the BSD license. Java 6+ is required for using the library, both at compile time and at runtime.
Here is Kirill's introduction to Trident 1.2:
The Trident animation library was born in February 2009 out of the internal animation layer used in Substance look-and-feel over the last three years. A year after, it is nearing its third official release which focuses mainly on stabilizing the API and ironing out the existing bugs.
The major milestone for this release is moving Substance 6.0 to use Trident – along with validating the library performance and flexibility to support a wide variety of UI animations. Trident 1.2 has also added a few new APIs to address a few common application requirements.
In his post, Kirill covers the new Trident 1.2 custom property accessors in detail, including demonstrating the features with several example code snippets related to timelines. The new custom accessors include getWith(PropertyGetter) and accessWith(PropertyAccessor).
You can use the same getter / setter / accessor implementation to access multiple fields – using the fieldName parameter passed to the get() and set() methods.
Kirill also talks about stopping a timeline. The Timeline.end() API is new in Trident 1.2:
The timeline transitions to the done state, with the timeline position set to 0.0 or 1.0 – based on the direction of the timeline. After application callbacks and field interpolations are done on the done state, the timeline transitions to the idle state. Application callbacks and field interpolations are done on this state as well.
OSGi focusses on modularity and it is right now (future may change it) the only viable way to split your application into modules with well-defined dependencies. It solves, however, "only" the technical problem - which is actually relatively easy. Before you going to introduce OSGi into your project, answer the following questions: 1. What is your versioning scheme for modules(bundles)? Do you care about minor versions, major versions etc? 2. Whats your scm strategy - do you plan to open and maintain a branch for every version of a module? How many branches do you plan to maintain? (with svn? :-)) ...
Last June, I introduced my
Painter's Canvas article, which presents a technique for
rendering complex graphics (such as fireworks, plasma, fractals,
and fire). Instead of relying on nodes and
javafx.scene.shape.Path objects (such as
javafx.scene.shape.LineTo) to render the graphics,
this technique relies on the concepts of canvas and painter for
this task. The crux of the article's code is the line iv.image =
SwingUtils.toFXImage (painter.renderImage (width, height))
(excerpted from the Canvas class's
paint() function). This line, which is repeatedly
invoked in an animation loop, performs several tasks to ensure
that the next animation frame is displayed...
There is my proposal for JUG-AFRICA agenda. Everyone is free to comment and add interesting ideas. I will detail each point in my blog later. * Continue to affiliate JUGs and share our experience with new JUGs; * Elect a president and a vice president (last week of april 2010); * Increase our visibility by both ways internal and external (very important)...
Last time we looked at writing command and shortening the URLs using simple TinyURL API. This time, lets try to take this one step furter and generate URLs that are mobile-users friendly, i.e. URLs that can be easily recognized and processed by various mobile devices. Such are urls in QCode or DataMatrix scan codes. I'm sure almost everybody have seen those somewhere already, be it on printouts or on the actual websites. In difference to the classic bar code QCode or DataMatrix are rectangular...

Our Spotlight this week is the work of our friend Felipe Gaúcho, who suddenly passed away on Friday, March 5. Felipe was a CEJUG founder and leader, a Java evangelist, and a long-time java.net collaborator. The self-description he wrote for java.net: "Felipe Gaúcho works as senior software engineer at Netcetera AG in Switzerland. He is a well known Brazilian JUG leader and open-source evangelist. Felipe works with Java since its early versions and has plans to keep that Java tradition as it is. When he is not coding, he prefers to listen reggae and travel around with his lovely wife Alena and his son Rodrigo."
We just published a new java.net Feature Article, Dibyendu Roy's Rethinking Multi-Threaded Design Principles; in the emerging multicore/multiprocessor world, multi-threaded programming is critical, in my view. We're also featuring Has JDBC Kept up with Enterprise Requirements? by Jesse Davis; in the article, Jesse invites us to look beyond Type 4 architecture to address the latest requirements of the enterprise Java ecosystem. And, Adhir Mehta's Java Tech article, Web Service Simulatino Using Servlets also remains in the Featured Articles section of the java.net home page.
