I added some new features to the visual designer I mentioned a few days ago. Now there is automatic synchronization from the view to the source (not yet from the source to the view), as well as better checking about where the drop can take place, i.e., the "logo" can only be in the header, etc, as well as a drop image, if the item can be dropped. Video speaks better than words: Source code: https://java.net/projects/nb-api-samples/sources/api-samples/show/versions/7.4/misc/Graph...

In the air traffic management (ATM) domain, System Wide Information Management (SWIM) is a new open standard-based information infrastructure which will connect all ATM stakeholders, aircraft as well as all ground facilities. In the recently held annual SWIM innovation contest, where innovations in software related to this domain are highlighted, Barco Orthogon won the top prize, in one of the two categories, namely "applications", with a NetBeans Platform solution. So, here...

Here's a new NetBeans Platform sample that puts many typical things together and gets you jump started when creating some kind of designer. The movie above is silent. It shows how to create a new XML file of the type managed by the application. It shows you can drag items into certain regions of the visual designer, i.e., items in the Header category of the Palette can only be dropped in the top of the three widgets, items in the Body category only in the middle, etc. Then...

Finding the place in the Options window where you can list the classes you'd like to exclude from the Code Completion box is not easy.Therefore, in NetBeans 8, you can exclude the classes you don't need right from within the Code Completion box. Below, notice the lightbulb at the far right in the currently selected item in the Code Completion box, which appears the second time you call up code completion: Press Alt-Enter or click the lightbulb and now you see this: Press Enter...

I believe this image to represent the essence of the key features of NetBeans IDE 8. For more: https://netbeans.org/community/releases/80

So you're happily using JTattoo in your NetBeans Platform application. However, when you use the darker variations, such as "com.jtattoo.plaf.graphite.GraphiteLookAndFeel", you run into a problem. Though all the colors change as you'd expect... there's still the white background at the top of the Options window, as you can see below.  That may seem like a small and insignificant problem. However, in the real world, Java and the NetBeans Platform are to be found in air traffic...

A first attempt at JTattoo usage in a NetBeans Platform application. To achieve the above, create a new module that wraps JTattoo, and in a different module set a dependency on the JTattoo module and then include the following: @OnStartpublic class Startable implements Runnable { @Override public void run() { try { UIManager.setLookAndFeel("com.jtattoo.plaf.smart.SmartLookAndFeel"); } catch (ClassNotFoundException ex) { ...

One thing I don't like about doing JavaScript in NetBeans IDE is the very wide code completion box, see below. Doesn't even fit in this blog, it's so wide, nor in the browser when you enlarge it below, without scrolling. In NetBeans IDE 8, there's a new option to configure the width of the code completion box for JavaScript. You can see it below, "Code Completion Item Signature Char Width", which is set to 40 by default, but I prefer 10: And now the code completion box is much...

If you want a simple security mechanism for the NetBeans Platform, go here: https://blogs.oracle.com/geertjan/resource/SecurityMechanism.zip  Run the attached from NetBeans IDE 7.4. If you're not logged in as 'admin', there's no Admin menu. Otherwise, there is. The @OnStart, i.e., this is the new way of doing ModuleInstall classes, no need to register in the Manifest: @OnStartpublic class Startable implements Runnable { @Override public void run() { ...
