Sizing error

Question

Okay, so I have this formatting code:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.util.*;
public class Gui1{
     JTextArea area;
     JScrollPane area0;
     JTextField field;
     JTextField field2;
     JPanel panel;
     ArrayList good = new ArrayList();
     ArrayList bad = new ArrayList();
     Gui1 gui;
     JPanel contentPanel;
     public static void main(String[] args){
          Gui1 gui = new Gui1();
          gui.start(10,gui);
     public void start(int bg, Gui1 g){
          gui = g;
          panel = new JPanel();
          JPanel panel2 = new JPanel();
          panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS));
          panel2.setLayout(new BoxLayout(panel2, BoxLayout.X_AXIS));
          field = new JTextField();
          field2 = new JTextField();
          JButton button = new JButton("Set");
          button.addActionListener(new SetterListener());
          JButton button2 = new JButton("Ready!");
//          button2.addActionListener(new GoListener());
          JButton button3 = new JButton("AutoAdd");
          button3.addActionListener(new AutoListener());
          panel.add(field);
          panel.add(field2);
          panel.add(panel2);
          panel2.add(button);
          panel2.add(button3);
          panel2.add(button2);
          JFrame frame = new JFrame("Diff'rent window select");
          frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          contentPanel = new JPanel();
          contentPanel.setBackground(Color.darkGray);
          contentPanel.setSize(200,200);
          area = new JTextArea(27,43);
          area.setText("Game created. \n");
          area0 = new JScrollPane(area0);
          area.setLineWrap(true);
          area0.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS);
          area0.setHorizontalScrollBarPolicy(ScrollPaneConstants.HORIZONTAL_SCROLLBAR_NEVER);
          JPanel holder = new JPanel();
          JPanel holder2 = new JPanel();
          JButton areaButton = new JButton("Show TextCode");
          areaButton.addActionListener(new AreaShowListener());
          JButton panelButton = new JButton("Show Game");
          panelButton.addActionListener(new PanelShowListener());
          holder2.setLayout(new BoxLayout(holder2, BoxLayout.X_AXIS));
          holder2.add(panelButton);
          holder2.add(areaButton);
          area0.setVisible(false);
          area.setVisible(false);
          holder.add(contentPanel);
          holder.add(area0);
          holder.setBackground(Color.green);
          frame.setSize(500,500);
          frame.getContentPane().add(BorderLayout.CENTER, holder);
          frame.getContentPane().add(BorderLayout.NORTH, holder2);
          frame.getContentPane().add(BorderLayout.SOUTH, panel);
          frame.setVisible(true);
//          for(int y=1; y<=bg; y++){
//               bad.add(new Badguy(0,y));
          field.requestFocus();
//     public void go(Gui1 g){
//          panel.setVisible(false);
//          while((!good.isEmpty()) && (!bad.isEmpty())){

//                    g.area.append("Badguy "+baddy.getId()+" survived. \n");
//          }else if(bad.isEmpty()){

     class AreaShowListener implements ActionListener {

//               good.add(new Melee(x,y));
               area.append("New goodguy at ("+x+"x"+y+"). \n");
               field.setText("");
               field2.setText("");
               field.requestFocus();
//     class GoListener implements ActionListener {

//                    good.add(new Melee(1,i));
                    area.append("New goodguy at (1x"+i+"). \n");
               field.setText("");
               field2.setText("");
               field.requestFocus();
}(That's just formatting, so the //'d stuff doesn't apply,)
But if you compile and run it, the JTextArea is 1 pixel, and the JPanel is very small too. If you remove the JScrollPane from the picture, though, the JTextArea is (about) the right size!
How do I make the size of the JScrollPane and JPanel adhere to the size of the panel they are in? Help!

Answer 1

Your posting has too much unnecessary code to look at.
We don't want to see you commented out code so get rid of it.
We don't care about your ActionListener code, so get rid of it.
We don't care about the components added to the North and South of the content pane since they are displayed correctly.
Once you get rid of all this unnecessary code, then maybe we will be able to see what you are actually doing and find the problem.
Its called a SSCCE. You need to create a [url http://homepage1.nifty.com/algafield/sscce.html]Short, Self Contained, Compilable and Executable, Example Program (SSCCE) that demonstrates the incorrect behaviour.
