The JavaFX SDK Packages are Taking Shape

Now that we're getting close to the Technology Preview Release of the JavaFX SDK, the classes that have been created so far have been organized into a more fine-grained package structure.  The impact is mainly in the import statements as you can see in this updated Hello/Goodbye example from a previous post.  As a quick reference, the list below contains the packages in JavaFX and the classes that are contained in each package.  By the way, you can download the latest Technology Preview Release here

and see the API documentation in more detail.

Some Other Recent/Upcoming Changes

There have been a couple of changes to JavaFX language syntax recently: 

• The "not equals" operator used to be <> but has been changed to the Java-style !=
• The modulus (remainder) operator has been changed from % to mod.

Also, a new web services library is in the works that will make it even easier to communicate with remote services required by your application.  As a result, the JSON and XML libraries are being pruned from the Technical Preview Release branch, but they are still available in the SVN repository if you need them.  You can read the current thinking about the web services library in this message on the [email protected] mailing list.  As is typical with JavaFX libraries, the likely outcome will be a simplification of the design in that message.

Finally, I'd like to point out something that is very exciting to me -- the fact that JavaFX is migrating to a "node-centric" approach.  As you may know, underneath the covers of the JavaFX UI for the desktop are Java Swing (components) and Java2D classes (graphical nodes).  Eventually, most UI constructs in JavaFX will be graphical nodes, including the components (e.g. Button) and layout panels (e.g. BorderPanel).  This will eliminate the need for using "adapter" classes like Canvas (to place a node on a panel) and ComponentView (to place a component on a Canvas).  This will also make it easier to create UIs that have an "iPhone look and feel" that users will increasingly expect.  As you can see by the fact that Dialog, Frame and Window exist in two packages (javafx.application and javafx.ext.swing), this migration has already begun.  An examination of the JavaFX documentation for the Frame class in the javafx.application package, for example, will show you that the content attribute of its Window superclass contains a sequence of Node objects.  Compare this with the Frame class in the java.ext.swing package whose Window superclass has a content attribute that still contains a sequence of Component objects.  The latter, by the way, will be around at least until the migration to a node-centric UI is complete.

Have fun, and please post a comment if you have any questions!

Hi!

It's a great article for me, a newbie in JavaFX. I try to run your code in Netbeans 6.7.1, but i've got so may errors. The most important error is, all the import packages are unavailable. The compiler could not found the class. Once i populate all classes, my classes are so different with you've populated in this article. I'm using JavaFX 1.2.. any clue? i really need this clue Sir.

Thank you

Bill,
There are a couple of options available now to create a grid of nodes
1) Use HBox and VBox, as shown in the following Create a Simple Calculator series:
http://javafxpert.com/weblog/simple-calculator-app/

2) Use the new Grid class in the JFXtras project. See the following post:

Hi James !!

It's nice to see your blog and thanks a lot for your javafx script book. It helped me a lot in uderstanding the structure for writing my basic script. I wanted to know that If I have to make a big appliaction and required handling database,logging,network,internationlization etc, then will it be suitable to use JavaFx. Can we use any existing framework like Swing application framework to support life cycle. Please help
Thanks
Shahid
