Let's say we want to make a coffee machine on the NetBeans Platform. It can be enabled... ...it can also be disabled: However, interestingly, the checkbox to enable the coffee machine is in one module, while the window that shows the results of the coffee production is in a different module: There is no dependency between the two modules, i.e., the one module does not use code or refer to code in the other module. Because the two modules are loosely coupled, we can easily...

Let's use the org.openide.explorer.propertysheet.PropertyPanel component, a generic GUI component for displaying and editing a JavaBeans property: The window in the lower left above uses the PropertyPanel, in fact all 3 components you see there are PropertyPanels. (So does the Properties window that you see above, but that's a predefined component that uses the PropertyPanel, while in this blog we want to create a custom component that uses PropertyPanel too.)...

Guess what, I'm in China, at JavaOne in Beijing. Visited the Forbidden City, among other things, as well as the Great Wall: Oh yeah, also hanging out at the NetBeans booth at the conference. Listening to Adam Bien right now, it's great to be here. Also had some excellent Peking duck the other day.

Yesterday @petrjiricka mentioned the new Cobertura support for Maven projects in NetBeans IDE. So I tried it out today, using a NetBeans IDE 7.0 development build from 6 December 2010. Once you have specified the reporting tags for Maven-Cobertura in the module where your tests are found, or for the whole application, you get a new menu item on the level (either application-level or module-level) on the right-click popup menu of the project in the Projects window. Then you...

I recreated the NetBeans Paint Application (see here and here) on top of Maven in IntelliJ IDEA: My run configurations in IntelliJ IDEA: Run: nbm:run-platform (working directory: /foo/bar/Paint/application) Build: clean reactor:make -Dmake.folders=application (working directory: /foo/bar/Paint) Test: test (working directory: /foo/bar/Paint) As you can see, I haven't looked at debugging yet. For testing, I have set up functional tests for the Maven-based NetBeans Paint Application...

This is the moment I've been waiting for, for a very long time: Register default TopComponent location via annotations Nov 30 '10; API spec. version: 6.37; affected top-level classes: TopComponent; made by: jtulach; issues: #191407 Use TopComponent.Registration, TopComponent.Description and TopComponent.OpenActionRegistration to register default location of a TopComponent, some of its properties and action to open it.

Maybe you'd like your users to open your NetBeans-based projects from the command line. If so, here's how: @ServiceProvider(service = OptionProcessor.class)public class OpenProjectOptionProcessor extends OptionProcessor { private static Option project = Option.requiredArgument(Option.NO_SHORT_NAME, "project"); @Override public Set<org.netbeans.spi.sendopts.Option> getOptions() { return Collections.singleton(project); } @Override protected void...

I visited Monaco yesterday, after doing NetBeans presentations at the Riviera JUG in Nice, France, the day before. Monaco is only a short train ride from Nice. A very large application on the NetBeans Platform (over 300 modules) is created in Monaco (as well as in England and Malaysia) by Experian, in the credit risk management sector. Read about that project here. So, in Monaco, I talked about the latest NetBeans Platform features to a group of developers from Experian. One...
