Create a JTable inside a JTabbedPane using Swing UI designer - Intellij

Question

I'm trying to create a frame with multiple tabs, each with a different list. I've used the Swing UI designer with Intellij to create the "assets" and then modified them in my main class file. I've looked up some examples of creating a JTable using the designer, but these don't use multiple tabs, which I think is the main problem for me right now as I am not able to figure out how to do it.

This is the code for now.

package client;

import javax.swing.*;
import javax.swing.table.TableModel;
import java.awt.event.*;

public class ATCGUI extends GUI {

    private JPanel mainPanel;
    private JTabbedPane tabbedPanel;
    private JPanel tabbedAirportInfo;

    private JScrollPane scrollPane;
    private JButton addButtonOut;
    private JButton deleteButtonOut;
    private JButton addButtonIn;
    private JButton deleteButtonIn;
    private JTable tableOut;
    private JTable tableIn;
    private JPanel panelOut;
private JScrollPane tabbedPaneOut;

    public ATCGUI(String AirportCode) {

        this.add(mainPanel);

        String airportID = getID(AirportCode);

        TableOut(airportID);

        pack();
        setVisible(true);
        setDefaultCloseOperation(DISPOSE_ON_CLOSE);
    }

    private void TableOut(String airportID){
        String[] columnNames = {"Airline", "Destination", "Aircraft"};

        Object[][] dataTest = {{"Iberia", "London", "737"}, {"AirEuropa", "Paris", "320"}, {"BritishAirways", "Berlin", "330"}};

        JTable TableOut = new JTable(dataTest, columnNames);

        setContentPane(panelOut);
    }
    public static void main(String[] args) {
        new ATCGUI("MAD");
    }
}

For now it shows the different tabs, but the JTable doesn't appear in any of the tabs. And I did make sure to put the JTable inside a JScrollPane.

I'm pretty new to this so maybe there's something I've missed out or just simply don't know.

Without your JTabbedPane code it will be difficult to suggest what you can "fix" in your own code.

This is a good reference for using a JTabbedPane with multiple tabs:

https://docs.oracle.com/javase/tutorial/uiswing/components/tabbedpane.html

An example of how JTabbedPane might be used with your data:

package whatever;

import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTabbedPane;
import javax.swing.JTable;

public class MyGui extends JFrame {

    private JTabbedPane tPane;

    MyGui(String t){
        super(t);
        this.tPane = new JTabbedPane();
        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        tPane.addTab("Tab 1", createTab());
        tPane.addTab("Tab 2", createTab());
        tPane.addTab("Tab 3", createTab());
        tPane.addTab("Tab 4", createTab());
        this.setContentPane(this.tPane);
        this.setSize(400, 400);
        this.setVisible(true);
    }
    
    public static void main(String[] args) {
        new MyGui("My Tabbed App");
    }

    private JScrollPane createTab(){
        String[] columnNames = {"Airline", "Destination", "Aircraft"};
        Object[][] dataTest = {{"Iberia", "London", "737"}, {"AirEuropa", "Paris", "320"}, {"BritishAirways", "Berlin", "330"}};
        JTable tableOut = new JTable(dataTest, columnNames);
        return new JScrollPane(tableOut);
    }
}
