I am trying to make an application which will allow you to create and play and Jeopardy! board. While creating the GUI I seem to have hit a road bump. A JPanel (scrollPanel1) does not seem to be showing up in my JScrollPane (scrollPanel1). I’m pretty sure that the JScrollPane is there because when I set the Scroll Bar Policy to always show the scrollbars the scrollbars are visible. But I don’t think the JPanel is showing up within. I would appreciate some help.

Here’s the code:

import java.awt.*;
import javax.swing.*;

public class CreateNewBoardGUI {
    private JFrame mainFrame;
    private JPanel mainPanel;
    private JPanel boardInfo;
    private JLabel boardNameLabel;
    private JTextField boardNameField;
    private JTabbedPane catTab;
    private JPanel tabPanel1;
    private JPanel catNamePanel1;
    private JLabel catNameLabel1;
    private JTextField catNameField1;
    private JScrollPane scrollPane1;
    private JPanel scrollPanel1;
    private JPanel qPanel1;
    private JLabel qLabel1;
    private JTextField qField1;

    public void CreateNewBoardGUI(){
        mainFrame = new JFrame("Create new Jeopardy! board");
        mainPanel = new JPanel();
        boardInfo = new JPanel();
        boardNameLabel = new JLabel("What would you like this board to be called?");
        boardNameField = new JTextField();
        catTab = new JTabbedPane();
        tabPanel1 = new JPanel();
        catNamePanel1 = new JPanel();
        catNameLabel1 = new JLabel("What would you like the category to be called?");
        catNameField1 = new JTextField();
        scrollPane1 = new JScrollPane();
        scrollPanel1 = new JPanel();
        qPanel1 = new JPanel();
        qLabel1 = new JLabel("200 Point Question");
        qField1 = new JTextField();

        mainPanel.setLayout(new BorderLayout());
        boardInfo.setLayout(new BorderLayout());
        tabPanel1.setLayout(new BorderLayout());
        catNamePanel1.setLayout(new BorderLayout());
        scrollPanel1.setLayout(new BorderLayout());
        mainFrame.setSize(700, 900);
        mainFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        mainFrame.setResizable(false);
        mainFrame.setLocationRelativeTo(null);
        mainFrame.setVisible(true);

        qPanel1.add(qLabel1);
        qPanel1.add(qField1);
        scrollPanel1.add(qPanel1, BorderLayout.NORTH);
        scrollPane1.add(scrollPanel1);
        tabPanel1.add(scrollPane1, BorderLayout.CENTER);
        catNamePanel1.add(catNameField1, BorderLayout.CENTER);
        catNamePanel1.add(catNameLabel1, BorderLayout.NORTH);
        tabPanel1.add(catNamePanel1, BorderLayout.NORTH);
        mainPanel.add(catTab, BorderLayout.CENTER);
        boardInfo.add(boardNameField, BorderLayout.CENTER);
        boardInfo.add(boardNameLabel, BorderLayout.NORTH);
        mainPanel.add(boardInfo, BorderLayout.NORTH);
        mainFrame.add(mainPanel);

        catTab.addTab("Category 1", tabPanel1);





    }
}

Thanks in advance.

    Remove the scrollPane1 = new JScrollPane();

    and add this instead(after creating scrollPanel1 instance):

    scrollPane1 = new JScrollPane(scrollPanel1);

    This will force the scrollPane1 to have scrollPanel1 as its ‘viewport’.

    To see how things are going you should set a background color:
    scrollPanel1.setBackground(Color.red);
    Add different colors to the pannel to study their behaviour.

    It should add the scrollbar as soon as you stretch it out of the tab panel.

    Note: Take a look into the ‘null layout’. It should be easier to deal with.

    Let me know if this helps or if you still have any trouble.
