JList.setModel() from NetBeans

Here's what I want:

public class ListSample {
  public static void main(String args[]) {
    String labels[] = { "A", "B", "C", "D","E", "F", "G", "H","I", "J" };

    String title = "JList Sample";
    JFrame f = new JFrame(title);
    f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    JList list = new JList(labels); //Jlist to array!!!!!!
    JScrollPane scrollPane = new JScrollPane(list);

    Container contentPane = f.getContentPane();
    contentPane.add(scrollPane, BorderLayout.CENTER);

    f.setSize(200, 200);
    f.setVisible(true);
  }
}

However, I can't seem to find the button to allow me to edit the
particular code from within NetBeans to accomplish this seemingly simply
task.

Here's what I have:

thufir@arrakis:~/bcit-comp2611-project2/src$
thufir@arrakis:~/bcit-comp2611-project2/src$ cat a00720398/view/Tabs.java
| head -n 86 | tail -n 8
      //pre-initialization code@@@@@@@@@@@@@
      guestsList.setModel(new javax.swing.AbstractListModel()
      {
         String[] strings = { "guest 1", "guest 2" };
         public int getSize() { return strings.length; }
         public Object getElementAt(int i) { return strings[i]; }
      });
      //post initialization @@@@@@@@@@@@@@@
thufir@arrakis:~/bcit-comp2611-project2/src$
thufir@arrakis:~/bcit-comp2611-project2/src$

What I want is:

guestsList.setModel(myArray); //that's it

I'd like to do this from within the GUI builder, just can't figure out
which button to click.

thanks,

Thufir
