How do you regenerate autogenerated code in NetBeans?

  1. Create a project in NetBeans and create a new JFrame.

  2. Use the GUI Builder to drag some components like a button or label onto the frame and look and the source. You'll see by default that the member variables are private in the frame class.

  3. Now go to Tools -> Options -> Misc -> GUI Builder and change something like the variables modifier to protected instead of private.

Now how do you apply those changes to the already generated code? I've tried several things like format code, fix code, etc. I've even tried cutting all the components off of the frame and then repasting them hoping to fix the issue, but it still uses the old settings.

When I create a new JFrame in the project and perform step 2 again, the changes have taken effect. Any new code generated on a new frame or file works as expected, but not the original.

This is very strange behavior, and I have to imagine there's an easy straight forward way to regenerate this code. Am I missing something?

I'm using NetBeans 7.1 and Java 7u2. Thanks in advance!

As you have already alluded to, the GUI Builder options are defaults only, for the creation of the form.

You can change most things about already-generated GUI elements.

To change the GUI components 'access' from private to protected, right-click the component in the GUI designer and select "Customize Code". At the bottom of the "Code Customizer" dialog you can change just about any aspect of the declaration of the GUI element. That dialog also lets you customise things like the constructor used for the element.

I would recommend you leave the access default at private, and only change the elements that you really need to be protected or even public.

And don't listen to the doom-sayers. We have over 600 GUI-designed forms in our application, we use the GUI designer every day, with multiple developers, and we very rarely have any issues at all.

By the way, we are using version 6.9.1 of NetBeans with Java6, so YMMV.
