I watched and listened to the conversation by James Gosling with the Silicon Valley Java User Group sometime ago. (Here on YouTube.) It is two hours long. If you stick around until 5 minutes before the end, Gosling says: "If I had to say I'm jaded it's sort of about the fact that people's attention is so focused on the web. And it feels to me like that's 10% of the computing landscape. If you look at what goes on in, say, biology. Huge, huge computational problems in biology....

@Overridepublic void requestVisible() { Mode mode = WindowManager.getDefault().findMode("explorer"); if (mode != null) { mode.dockInto(this); this.open(); }} The above is code inside a TopComponent that, by default (i.e., via layer.xml registration) docks in "explorer" mode. With the above, when the TopComponent is minimized, it will redock in the "explorer" mode whenever the mouse hovers over the button in the left sidebar, i.e., the visualization of...

I've been looking at a very interesting application that someone on one of the recent NetBeans Platform courses has been working on. It is a Swing application, created in Eclipse. The purpose of the application is to provide a visual calculator, for scientific calculations of various kinds. The sources, as I received them, were structured as follows: Aside from a GUI, the application provides abstract classes that model the objects that need to be calculated. For example,...

NDVis is a free tool for neuroscientists. It provides an interactive data visualization and analysis tool for large multidimensional databases: NDVis is currently used in neuroscience classes at Emory University and in ongoing research projects at Brandeis University and abroad. I've been in touch with its main developer, John Langton from VisiTrend, who is interested in moving some of his tools to the NetBeans Platform. From my side, the easiest one to get started with was...

In my layer: <filesystem> <folder name="Profiles"> <file name="DriverProfiles" url="nbresloc:/com/visitrend/ndvis/sql/gui/resources/DriverProfiles.xml"/> </folder></filesystem> The url above points to a package in a module, which contains the actual file I need to incorporate, i.e., "DriverProfiles.xml". Now, in my code: try { URL driverProfiles = new URL("nbfs:/SystemFileSystem/Profiles/DriverProfiles"); FileObject fo =...

Andrzej Olszak, one of the students here at the NetBeans Platform course at the University of Southern Denmark, is researching the feature-oriented decomposition of Java programs. That's of relevance to the NetBeans Platform because it provides a methodology for turning a monolithic application into one that is modular. Today during the course Andrzej presented his work and I recorded it. He showed a whole bunch of tools and graphs that help you analyze the features of your...

Odense, Denmark, isn't one of the world's largest places (still, the 3rd largest city of Denmark), which makes it all the more remarkable that there was such a large turnout (around 30) on the 1st day of the 3-day training held at the University of Southern Denmark today: After the course is over, the students will need to do a report, as part of their official university course: Deadline for the report is on the 18th of February. You may do the report individually or in...

The quick search popup appears when you start typing in a treeview, e.g., in BeanTreeView: By default, the search is by prefix, e.g., above, "D" is typed and immediately "Dick" is selected, since that string starts with "D". However, you can use this statement: beanTreeView.setUseSubstringInQuickSearch(true); ...and then the entered text is used as a substring in the search: Above, the "r" wouldn't have matched anything by default, since there's no string that starts with that...

The purpose of the previous blog entry was to explain how you can add project types as subprojects to your own project types. However, what about the scenario where you want to add project types as subprojects of project types created by others? For example, let's imagine you have a dedicated project type that could be relevant to programmers creating web applications in NetBeans IDE. In this scenario, you did not create the web application project type, so how can you...
