macOS jbutton problems between Windows/Mac

[canada eh]

I am currently in a high school programming class and we just started learning about jbutton in GUI applications. At school we use Jcreator 5.0 as our IDE but I use Netbeans 7.0 on a Mac. The problem I am having is that when I run the code he has given us to do an assignment the button itself doesn’t show up, only the text does. I can click the button with no problems there is just no borders. Here is the code. Thanks

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

public class GUIbutton implements ActionListener {
    // declare objects in window

    JFrame frame;
    JPanel contentPane;
    JLabel label1;
    JLabel label2;
    JButton button1;
    JButton button2;

    public GUIbutton() {    // this constructs the GUI object and


        // Create and set up the frame 
        frame = new JFrame("JButtons on a GUI");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        // the box layout puts objects in a vertical column 
        contentPane = new JPanel();
        contentPane.setLayout(new BoxLayout(contentPane, BoxLayout.PAGE_AXIS));
        contentPane.setBorder(BorderFactory.createEmptyBorder(20, 20, 20, 20));
        contentPane.setBackground(Color.red);

        // Add content pane to frame 
        frame.setContentPane(contentPane);


        // Create and add label1 
        label1 = new JLabel("Good Morning ICS4U !");
        label1.setAlignmentX(JLabel.CENTER_ALIGNMENT);
        label1.setBorder(BorderFactory.createEmptyBorder(20, 20, 20, 20));
        label1.setForeground(Color.white);
        contentPane.add(label1);

        // create button1
        button1 = new JButton("English");
        button1.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10));
        button1.setAlignmentX(JButton.CENTER_ALIGNMENT);
        button1.setBackground(Color.blue);
        button1.addActionListener(this);
        contentPane.add(button1);

        // create button2
        
        button2 = new JButton("French");
        button2.setBackground(Color.white);
        button2.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10));
        button2.setAlignmentX(JButton.CENTER_ALIGNMENT);
        //button2.setBackground(Color.white);
        button2.addActionListener(this);
        contentPane.add(button2);

        // create label2
        label2 = new JLabel("Java Applications can run on any platform.");
        label2.setAlignmentX(JLabel.CENTER_ALIGNMENT);
        label2.setBorder(BorderFactory.createEmptyBorder(20, 20, 20, 20));
        label2.setForeground(Color.white);
        contentPane.add(label2);

        // Size and then display the window. 
        frame.setSize(500, 300);
        frame.setLocation(300, 300);
        frame.setVisible(true);

    }

    public void actionPerformed(ActionEvent event) {

        String eventName = event.getActionCommand();

        // check to see which button is clicked

        if (eventName.equals("French")) {
            label1.setText("Bonjour ICS4U !");
            label2.setText("Les applications Java peuvent fonctionner sur n'importe quelle plate-forme. ");
        }

        if (eventName.equals("English")) {
            label1.setText("Good Morning ICS4U !");
            label2.setText("Java Applications can run on any platform.");

        }

    }

    public static void main(String[] args) {

        // create  a GUI called g1 and run !
        GUIbutton g1 = new GUIbutton();

    }
}

Remove the borders being assigned to the JButtons with setBorder().

JButtons on Mac OS X are not infinitely customizable. If you add a border, it will no longer be drawn as a typical pushbutton. You also can't change the JButton's colors arbitrarily.

That worked perfectly!

I did notice that the border colouring I tried to do didn't work, thats what my teacher recommended I try.

Thanks a lot!
