Right now, it's not possible to register this as an Action: package org.demo;import java.awt.Component;import javax.swing.JLabel;import org.openide.awt.ActionRegistration;import org.openide.awt.ActionReference;import org.openide.awt.ActionReferences;import org.openide.awt.ActionID;import org.openide.util.actions.Presenter;@ActionID(category = "File", id = "org.demo.SomeAction")@ActionRegistration(displayName = "not-used")@ActionReferences({ @ActionReference(path =...

Here's how you could construct an Admin Window in an application based on NetBeans Platform 7.1: package org.netbeans.paint; import org.openide.util.NbBundle; import org.openide.windows.TopComponent; @TopComponent.Description(         preferredID = "AdminTopComponent",         iconBase = "/org/netbeans/paint/new_icon.png",         persistenceType = TopComponent.PERSISTENCE_ALWAYS) @TopComponent.Registration(         position = 10,        roles = {"Admin", "Boss"},        mode...

During a JavaOne IDE-comparison session, in a valiant effort to prove my impartiality, I revealed some of my pet peeves about NetBeans IDE. One of these was this odd scenario: Above, I have called up a hint to convert an if-else statement to a strings-in-switch statement. However, annoyingly, there's also a tooltip, a meaningless tooltip, taking up space and blocking part of my code. Here's another example: To me, this looks messy and, worst of all, blocks me from seeing part...

Realized that for the first time in years I hadn't yet blogged about JavaOne. (Whether stated explicitly or not, my blog is increasingly focused purely on providing a succinct list of solutions to specific problems I get asked about in one way or another. For example, yesterday's blog entry is a response to a question from Stanford University, where they're doing some amazing work in biomechanics with NetBeans, but more about that another time.) Time to rectify that. To me,...

Let's create a simple text editor and set up a file on disk to be double-clicked for opening into the simple text editor. So, a file will be on disk, I will double-click the file, the simple text editor will start up, and automatically my text file will be open in the simple text editor. I can then immediately start working with the file in the editor. No coding will be required for all this functionality. Create the Application. Start NetBeans IDE, go to the New Project dialog...

Reading through the NetBeans API Changes List today, I came across this, which applies to 7.1 releases of NetBeans IDE: (Jul 16 '11) org-netbeans-modules-editor-lib2:Zoom text actions added That sounds cool and so I tried it immediately. Wooow. Works exactly as one would expect! Font size increases/decreases as I scroll (with mousewheel). Will be very handy in future NetBeans presentations. :-) On my non-mouse system, I hold down the Ctrl key and move my finger up/down in the...

In yesterday's blog entry, you saw most/all Actions relevant to Nodes demonstrated within the context of a single sample: However, what you do NOT see, in the screenshot above, are mnemonics. In other words, maybe you'd like to let the user use a single character on the keyboard (which is not the same as a keyboard shortcut) to invoke the various Actions shown above? If that support were present, you'd see a character in the items above underlined, indicatingwhich key on the...

Anyone using the Nodes API on the NetBeans Platform must have encountered the tricky difficulties in getting the cut/copy/paste/delete/move/reorder/drag/drop operations to work correctly. The examples and tutorials in this area tend to focus on one or two of these, rather than all in the same context, which can be frustrating. That's why it is great that Toni Epple has contributed a complete example, here: http://java.net/projects/nb-api-samples/sources/api-samples/show/versions...

In part 1, you saw Jesse Glick's solution for a JDesktopPane on the NetBeans Platform. I've been playing with the latest sources he's provided, which now work on 7.1: https://bitbucket.org/jglick/dynamicmenudemo So, now, when "Win1" is selected below, dedicated menu items and toolbar buttons appear in the main window: ...while, if Win2 is selected, other menu items and toolbar buttons are shown/hidden: If interested in this functionality, download the sources from the link above.
