Netbeans: Using GUI Builder on a Regular Java Class File

advertisements

I'm using Netbeans. When I create a Java class, I sometimes want to change it to be a GUI component so that I can visually edit it using the GUI Builder.

What is the necessary step to transform a regular Java class to a GUI component so that Netbeans would recognize it and allow me to use GUI Builder ? (i.e. switch between Source and Design)


NetBeans' Gui builder, Matisse, works off a .form xml file located adjacent to the source file. Matisse creates and maintains the .form file and the code generator creates/updates methods in the java source to reflect changes to the form.

Unfortunately, there is no support in NetBeans for free-form GUI construction.

The closest I've seen is FormGenerator. It's a contributed NetBeans module that adds a right click action to .java files that will attempt to generate a .form file from the .java source. It's very limited, but it's better than nothing. It works best if you've followed the coding style employed by Matisse.
