James L. Weaver

James Weaver’s JavaFX Blog Kevin Nilson, the leader of the Silicon Valley Web Developer JUG, relayed to me the idea of creating an application in JavaFX Script that consists of a wheel that has the names of JUG attendees on it.  The wheel would revolve and land on a name, who would then receive a prize. Today's post is a first cut at this, which also demonstrates several compiled JavaFX Script features. Here's a screenshot of the application: When the program starts up, a wheel with some fictitious names appears.  The user can click the dot in the center of the circle and enter a list of names (up to 60) in a dialog box, shown below: Clicking the OK button causes the names entered to appear in the wheel, as shown in the screenshot above.  Clicking the arrow on the left causes the wheel to spin, landing on a name, and showing a dialog box with the winner: Presuma...

JFX and the Way Forward After JavaOne 2008

James Weaver’s JavaFX Blog For me, JavaOne 2008 was enlightening, exhilarating and exhausting.  It was great meeting colleagues that I had only known via email and JavaFX mailing lists.  I'd like to especially thank all who suffered through my JavaFX University and technical sessions :-) There were several JavaFX-related announcements and demos at JavaOne, not the least of which is the preview release of the JavaFX SDK due in June 2008.  As the interpreted version of JavaFX was the prototype for the compiled version, the javafx.ui classes are the prototype for the javafx.gui...

Closures in Compiled JavaFX Script

From Jim Weaver's Learn JavaFX Weblog One of the very useful (and cool) features of compiled JavaFX Script will be closures.  In a nutshell, JavaFX Script closures provide the ability to define a function within another function with the inner function having access to the local variables of the outer function.  This feature is enabled by the fact that in compiled JavaFX Script, functions are first-class objects, which provides the ability to assign functions to variables and to pass functions as arguments to other functions.  You can read more about closures in this Wikipedia ...

Playing with UI Features in Compiled JavaFX Script

From Jim Weaver's Learn JavaFX Weblog As I've mentioned before, compiled JavaFX Script is currently under development, and one of the last pieces of the puzzle is the UI features. Currently there are a few UI features that are operational in the compiled version, for example Frame, BorderPanel and Button. Fortunately, the user interface API (widgets and 2D graphics) is almost identical to interpreted JavaFX Script, as is the declarative scripting. For example, this classic border layout (BorderPanel widget) example executes in the interpreted, and compiled versions of JavaFX Scrip... (more)

Compiled JavaFX Script Applet - Happy Holidays!

To wish you Happy Holidays (and if you'll permit me, a very merry Christmas) I wrote this Compiled JavaFX Script Applet (that executes in a browser).  For fast deployment I used the latest version of Java SE 6 Update 10 (formerly known as Java SE Update N, formerly known as Consumer JRE, formerly known as Prince :-D).  I also used the latest beta version of Firefox (Minefield 3.0 beta), as this is necessary if you want to use the Java SE Update 10 browser plug-in with Firefox.  Check out this video blog by Robert Eckstein for some great information about Java SE Update 10. The Java... (more)
