Netbeans template AboutBox Java

Question

I used this code previously in netbeans 6.9.1 but it does not seem to work in 7.1.1, it underlines .getApplication() with the hint "cannot find symbol".

How can I make this work again?

JFrame mainFrame = TestProject.getApplication().getMainFrame();
AboutBox newAboutBox = new  AboutBox();
newAboutBox.setLocationRelativeTo(mainFrame);
TestProject.getApplication().show(newAboutBox);

Here is a similar question, but the solution does not work.

Have you checked the static method getApplication() in TestProject.java? What does it show?

It doesn't show that method, in the TestProject class, but it didn't have it when I had netbeans 6.9.1 either, but it still worked, i assumed that it is a basic java method, but at this stage it lokks more like it was a netbeans class. – thewikus Mar 22 '12 at 10:22

I found the solution by re-installing netbeans 6.9.1. It appears that there is a built-in library that is not in 7.1.1. I also found that the template I used was the "Desktop Application" template.

This is the solution I came up with from that:

TestProject class:

import org.jdesktop.application.Application;
import org.jdesktop.application.SingleFrameApplication;

public class TestProject extends SingleFrameApplication {

    @Override protected void startup() {
        show(new AppView(this));
    }

    @Override protected void configureWindow(java.awt.Window root) { }

    public static TestProject getApplication() {
        return Application.getInstance(TestProject.class);
    }

    public static void main(String[] args) {
        launch(TestProject.class, args);
    }
}

AppView JFrame:

import org.jdesktop.application.FrameView;
import org.jdesktop.application.SingleFrameApplication;

public class AppView extends FrameView {
   public AppView(SingleFrameApplication app) {
       super(app);

       JFrame mainFrame = TestProject.getApplication().getMainFrame();
       AboutBox newAboutBox = new  AboutBox();
       newAboutBox.setLocationRelativeTo(mainFrame);
       TestProject.getApplication().show(newAboutBox);
   }
}
