Why won't my pane scroll?

[Brandi Love]

Hi All!

I've written the code below to create and show a GUI for a test program that I am creating. My problem , that when I put text larger than the scroll pane in either of the JTextAreas that I've created they do not scroll even though I've set them to. I can't figure out what - I must be missing something silly. Does anyone see a problem? I've bolded the important pieces of code. Please not that any variables I have not instantiated here are global - I'm positive I haven't forgotten to declare anything.

public void createAndShowGUI() {
frame = new JFrame("Programming Test:  Problem 1");
frame.setResizable(false);

panel = new JPanel(new GridBagLayout());

Color myGray = new Color(237, 237, 237);

panel.setBackground(myGray);

[B]inst = new JTextArea("test", 7, 40);
        inst.setEditable(false);
        inst.setLineWrap(true);
        inst.setWrapStyleWord(true);
        inst.setBackground(Color.white);
        instPane = new JScrollPane(inst);
        instPane.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_NEVER);
        instPane.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED); [/B]
        
        inst.setBorder(BorderFactory.createCompoundBorder(
        BorderFactory.createMatteBorder(5, 5, 5, 5, myGray),
        BorderFactory.createCompoundBorder(
        BorderFactory.createLineBorder(Color.black),
        BorderFactory.createEmptyBorder(10, 10, 10, 10))));
        
        [B]log = new JTextArea("test" , 3, 36);
        log.setEditable(false);
        log.setLineWrap(true);
        log.setWrapStyleWord(true);
        log.setBackground(myGray);
        logPane = new JScrollPane(log);
        logPane.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_NEVER);
        logPane.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED); [/B]
        
        logPane.setBorder(BorderFactory.createEmptyBorder(15, 15, 15, 15));

        JLabel programTitle = new JLabel("IFS Programming Test: Problem 1");
        programTitle.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10));
        
select = new JButton("Select Input File");
view = new JButton("View Output FIle");
save = new JButton("Save Output File");
exit = new JButton("Exit");

view.setEnabled(false);
save.setEnabled(false);

select.addActionListener(this);
view.addActionListener(this);
save.addActionListener(this);
exit.addActionListener(this);

GridBagConstraints c = new GridBagConstraints();

c.gridwidth = 4;
c.gridx = 0;
c.gridy = 0;
panel.add(programTitle, c);

c.gridy = 1;
panel.add(inst, c);

c.gridy = 2;
panel.add(log, c);

c.gridwidth = 1;
c.gridy = 3;
c.ipadx = 10;
c.ipady = 10;
panel.add(select, c);

c.gridx = 1;
panel.add(view, c);

c.gridx = 2;
panel.add(save, c);

c.gridx = 3;
panel.add(exit, c);

frame.getContentPane().add(panel);
        frame.pack();
        frame.setVisible(true);
}

You are adding inst to your container, when you should be adding instPane. You probably also want to set the border on instPane, not inst.

I knew I was missing something silly! I think I've been staring at the screen for far too long. Thanks, Brian!
