Bengt-Erik Fröberg from Sweden, one of the developers working on ProSang, the leading Scandinavian blood bank system (and based on the NetBeans Platform), is reworking the user interface of the JFugue Music NotePad. In particular, the Score window (named ScoreFX window below) contains components that are now quite clearly JavaFX, instead of Swing. Looks a lot better and also performs better. The sliders in the Keyboard window are candidates for being similarly redone to use...

What's the difference between these two methods, "test1" and "test2"? public int test1(String str) { return str.length();}public int test2(String str) { if (str == null) { System.err.println("Passed null!."); //forgotten return; } return str.length();} The difference, or at least, the difference that is relevant for this blog entry, is that whoever wrote "test2" apparently thinks that the variable "str" may be null, though did not provide a...

You're working on an application and this thought occurs to you: "Wouldn't it be cool if I could define rules specifying that all static members, initializers, and fields should always be at the top of the class? And then, whenever I wanted to, I'd start off a process that would actually do the reordering for me, moving class elements around, based on the rules I had defined, automatically, across one or more classes or packages or even complete code bases, all at the same...

In NetBeans IDE 7.3, a Backbone.js file can be generated from a Java RESTful web service. The Backbone.js file contains complete CRUD functionality and your HTML5 application can immediately be deployed to make use of those features. Coupled with the NetBeans IDE two-way editing support for HTML5, via interaction with WebKit in Chrome, Backbone.js users have a completely new and powerful tool for coding their HTML5 applications. The above is illustrated via the brand new...

Create a JavaScript file and refer to it inside an HTML file. Then put this into the JavaScript file: (function($) {     var CatCollection = Backbone.Collection.extend({         url: 'http://api.flickr.com/services/feeds/photos_public.gne?tags=cat&tagmode=any&format=json&jsoncallback=?',         parse: function(response) {             return response.items;         }     });     var CatView = Backbone.View.extend({         el: $('body'),         initialize: function() {            ...

In NetBeans IDE 7.3, bodies of newly created methods can now be customized in Tools/Templates/Java/Code Snippets, see below: The content of the first of the two above, "Generated Method Body", is like this: <#--A built-in Freemarker template (see http://freemarker.sourceforge.net) used forfilling the body of methods generated by the IDE. When editing the template,the following predefined variables, that will be then expanded intothe corresponding values, could be used together...
