Where in the world is this coming from?

Question

I've recently been contracted to build an application for my employer. Great. The project is really straight forward and its going along nicely ... all except for this simple bit here.
I decided to use a new "big & bad" IDE (Netbeans 5.5) seeing as how this was pretty GUI intensive. I don't like to have to sit down and calculate all of those dimensions and placements by hand. So ... am using the IDE.
Pasted below is the initComponents() method of my program where my JTree (jTree1) is instantiated. It has an empty constructor - and nothing has been added to it ... so I'm curious as to how this is happening:
The problem:
I've reviewed the code over and over again. I can't find anywhere where a default dataset is being assigned to the JTree. Anywhere. However, when I go to view my form - I have the following information in the tree:
JTree
|
Colors
|- blue
|- violet
|- red
|- yellow
|
Sports
|- basketball
|- soccer
|- football
|- hockey
|
Food
|- hotdogs
|- pizza
|- ravioli
|- bananas
Where in the name of Satan's assshole is this coming from?
    private void initComponents() {
        btnSend = new javax.swing.JButton();
        btnClose = new javax.swing.JButton();
        jScrollPane1 = new javax.swing.JScrollPane();

        jLabel1 = new javax.swing.JLabel();

        btnClose.setPreferredSize(new java.awt.Dimension(109, 23));
        btnClose.addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                btnCloseActionPerformed(evt);
        jTree1.setEditable(true);

                .addContainerGap())
        pack();
    }Nowhere else in the rest of the entire application is jTree1 even referenced. So, how is this? How is that data in my tree? Best question: how in the funk do I get it out??

Answer 1

Myeh - I'm not really in any rush. I work from home as a private contractor. I tell you - it is so much more ... relaxed? ... than when I was working for my previous employer. My current employer wants the product finished by June. Thats when they have a big push of students coming in and want the new software ready for them. So, I've got a while - and it definitely wont take me that long to complete. I just figured that there must be something to the fuss about IDEs and how they simplify things. And, tonight, I found that that is a load of horseshit.
(Just so you know - there is a downside to working for yourself... you get weird requests from people like the following ...)
I had a guy once ask me to write an application for his son who is obsessed with the television show Alias. He said he wanted a program that did exactly what this Alias program did on the show in a particular episode. When asked if I was familiar with it, I said no. So what does this goofball do? He goes and buys the show on DVD and brings it to me. We watch it - he takes me to the point in the show and says "That! Right there! That's what he wants!!"
Astonished (and somewhat dumbfounded) I ask him, "You're aware of the fact that I am not going to be capable of writing an application that remotely logs into a secret NSA super-computer via satellite ...... right?" He then proceeded to tell me to make it look like it does. Just make up all sorts of stuff - just as long as it looks the same.
The worst part .... that wasn't the only request of the type that I've received. (Granted, the others were by kids - usually 14 or 15 that thought that I'd do it for 10 or so bucks.) Because I obviously have time to waste on such things ...
