Let's say you have two toolbar buttons, one for expanding and the other for collapsing the currently selected node, as shown below, within the black box drawn on the screenshot: How to, from the two toolbar buttons above, expand/collapse the currently selected node? The answer is very similar to "Add Widget from Action in Toolbar". Start by creating two interfaces, one for expanding and the other for collapsing: public interface Expandable { void expand();} public interface...

The free Community Edition of forensics software Maltego Radium was released the day before yesterday: Details: http://maltego.blogspot.nl/2012/12/maltego-radium-community-edition.html Those guys make by far the coolest YouTube movies on their software releases, e.g., this recent one: http://www.youtube.com/watch?v=OSipLyYZQks

Updated the "Add Widget via Action in Toolbar" sample so that, when a new object is added to the canvas (via the red dot toolbar button below), a new customer is automatically added to the explorer view, below, after which any node selected in the explorer is automatically highlighted in the canvas, while any object selected in the canvas causes the related node in the explorer to be highlighted: This is a cool example illustrating communication between multiple modules, with...

I discovered, perhaps unsurprisingly, that it's possible to create a module that defines window groups consisting of windows defined in other modules, even (and that's the most fun part) windows over which you normally have no control, e.g., the windows defined in the NetBeans Platform itself, such as the Properties window, the Favorites window, and the Output window. Once you have defined a window group consisting of some of your own windows, plus some windows from the...

I've been in touch recently with Ann Maybury, who is creating a golf tournament roundrobin manager for senior citizens in Palm Desert, California. The application is created on the NetBeans Platform and looks as follows, very neat and professional: Ann has been working on wrapping up the application for distribution and needs to include the JRE, since end users of the application don't necessarily have the JRE installed when they install the application. Several blogs and...

Based on yesterday's blog entry, let's do something semi useful and display, in the project popup, which is available when you right-click a project in the Projects window, the time since the last change was made anywhere in the project, i.e., we can listen recursively to any changes done within a project and then update the popup with the newly acquired information, dynamically: import java.awt.event.ActionEvent;import java.text.DateFormat;import java.text.SimpleDateFormat;imp...

Very interesting thing and handy to know when needed is the fact that "menuText" and "popupText" (from org.openide.awt.ActionRegistration) can be changed dynamically, via "putValue" as shown below for "popupText". The Action class, in this case, needs to be eager, hence you won't receive the object of interest via the constructor, but you can easily use the global Lookup for that purpose instead, as also shown below. import java.awt.event.ActionEvent;import...

The question of the day comes from Vadim, who asks on the NetBeans Platform mailing list: "Looking for example showing how to add Widget to Scene, e.g. by toolbar button click." Well, the solution is very similar to this blog entry, where you see a solution provided by Jesse Glick for VisiTrend in Boston: https://blogs.oracle.com/geertjan/entry/zoom_capability Other relevant articles to read are as follows: http://netbeans.dzone.com/news/which-netbeans-platform-action http://netbe...
