Recently I blogged about Spring integration into the NetBeans module system. Here's how you would use that integration to enable the Print menu item for a TopComponent. In effect, what this example shows is how to use a Spring configuration file to extend a TopComponent's Lookup to include a PrintCookie:Implement PrintCookie, which requires a dependency on Nodes API: package org.yourorghere.nbspringdemo1;import javax.swing.JOptionPane;import org.openide.cookies.PrintCookie;pu...

The "Will Code for Food" competition takes us to... a small software company named cismet based in Saarland, a small state in Germany. The guys from cismet are the ones who created the "Log4J Logging Viewer plugin for NetBeans IDE". It is also known as BeanMill. On their Partners page, you can see that cismet is one of the NetBeans partners. "Thanks for the nice idea," writes Sebastian Puhl, one of the cismet developers, "we had fun making the pictures for the competition."...

In the screenshot below, the content of the "Spring Window" is injected via a Spring configuration file: The highlighted classes above are the Swing components and behavior that Spring injects into the TopComponent (except for 'SpringAction', which opens the window). In the editor area above, the following constructor is shown: private SpringTopComponent() { initComponents(); setName(NbBundle.getMessage(SpringTopComponent.class, "CTL_SpringTopComponent")); ...

How is that possible..? What did I do to include the hidden folders in the Favorites window? Answer: Tools | Options | Advanced Options | IDE Configuration | System | System Settings | Ignored Files.

NetBeans "enfant terrible" Jaroslav Tulach is writing a book on API design. It's looking pretty good and will certainly be interesting. Aside from teaching you everything you'll ever want to read about API design, it also presents an interesting history of several of the NetBeans APIs. You'll read why and how design decisions were made in NetBeans. You'll learn how to avoid the mistakes and benefit from all the wisdom of the API designers at NetBeans. Some great people are...
