When creating your own InplaceEditors, the NetBeans IDE sources are your friend. Here, for example, is a "RadioInplaceEditor" in action, which is based on the RadioInplaceEditor in the sources: Many more similar classes are found here: http://deadlock.netbeans.org/hudson/job/NB-Core-Build/ws/openide.explorer/src/org/openide/explorer/propertysheet/

If the command line does not contain the correct name, i.e., as follows: run.args.extra=--name admin ...then the Admin toolbar button (on the extreme left below) is disabled, e.g., here "henry" was passed in: ...otherwise, i.e., if "admin" is passed in, the menu item is enabled: How to do this, as simple as possible: Create a User POJO: public class User { static String name; public static String getName() { return name; } public void setName(String name) { ...

"netbeans.conf" is a file most NetBeans IDE users know about, since that's where the IDE's user directory and JVM arguments are defined. The same is true for any application created on top of the NetBeans Platform, i.e., each application has its own configuration file. When you choose "Build ZIP Distribution" in the IDE, or if you run the related Ant target on the command line, the default configuration file from "harness/etc/app.conf" is added to the ZIP distribution of your...

In the NetBeans Platform (i.e., not the tool NetBeans IDE, but the Swing framework beneath it [and many others]), 6.9 brings many enhancements. These, in my opinion, are the most important:NetBeans Platform as a Product. As announced by Jim Parkinson, Sun exec at the time, the post 6.8 scene, in terms of the NetBeans project, is markedly different from before, where there really only was one official project, that is, the IDE. That heralds a totally new vision to the pre-6.9...

Of the two people making my list of "Current Favorite Two (Male) People on My Favorite People List", one is named Scott Palmer. More about him some other time. The other is named "Thomas G." The G could stand for anything, as could the Thomas. I know not who that person is nor from whence he hails nor when he was instantiated. All of that notwithstanding, I post in its entirety the issue he posted (Feb 02, 2010) on the MyEclipseIDE site (here). Let it be known that I endorse...

I came across Petra Barus and his JSR-296 based Taekwondo Tournament Magament System yesterday. Petra gave me the sources of the app and I've been looking through them, and running the app itself, with the aim of porting it to the NetBeans Platform. Below, I want to share my initial thoughts relating to porting the application. Maybe it will give others pointers when doing the same with their own project. I.e., a logical first step is to just browse through the sources of...

Let's say you want a widget-based window where you have different regions, as shown here: The above widgets, within a Visual Library scene, are created as a result of parsing the following file, which is available in the "Text" tab of the multiview component: How to create these two regions? (Everything else in the scenario above has recently been described in this blog, from multiview component to parsing the XML file to serialization.) To create the above 50/50 split in the...

Lots of interest in workflow applications atop the NetBeans Platform, I believe, so let's create this today as an example: How to create the above from scratch: Create new NetBeans Platform application named "Demo Workflow". Create a new module within the application above, named "WorkflowUI", with code name base "org.demo.workflow.ui", together with a layer XML file. Create a new TopComponent via the "Window" wizard, in the "editor" position, with "Workflow" as class name...

I reported on the OfficeLAF for the NetBeans Platform sometime ago, so I'm happy to again have the opportunity of announcing a new NetBeans Platform LAF... the blue Look and Feel, which can have this impact on your application: Why was the above LAF created? It comes from the blue music composer (that's a link to an interview published today), where you'll find this explanation, by the LAF's author, Steven Yi: "blue's custom look and feel started off one day when I was using...
