What should I use instead of FlowLayout()?

Question

So, my JFrame is not turning out the way I want it to, because of the FlowLayout() but I don't know what else to use to fix this. It just makes my JButton fill the entire JFrame. Is there a way I can get FlowLayout() to apply my custom sizes and location for the JFrame components, or is there an alternative that could easily replace it?

Here is my code:

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

public class MTGSAMPServerReference extends JFrame implements ActionListener {

    public static Toolkit tk = Toolkit.getDefaultToolkit();
    static int ScrnWidth = ((int) tk.getScreenSize().getWidth());
    static int ScrnHeight = ((int) tk.getScreenSize().getHeight());

    private static final long serialVersionUID = 1L;
    private static JList list1;
    private static JButton next;

    public MTGSAMPServerReference() {
        // set flow layout for the frame
        this.getContentPane().setLayout(new FlowLayout());
        Object[] data1 = { "Value 1", "Value 2", "Value 3", "Value 4", "Value 5" };
        list1 = new JList<Object>(data1);
        next = new JButton("Next");
        next.addActionListener(this);
        // add list to frame
        add(list1);
        add(next);
    }
    @Override
    public void actionPerformed(ActionEvent e) {
        if (e.getActionCommand().equals("Next")) {
            int index = list1.getSelectedIndex();
            System.out.println("Index Selected: " + index);
            String s = (String) list1.getSelectedValue();
            System.out.println("Value Selected: " + s);
        }
    }
    private static void createAndShowGUI() {
        //Create and set up the window.
        JFrame f = new MTGSAMPServerReference();
        //Display the window.
        f.pack();
        f.setVisible(true);
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        f.setSize(1200, 800);
        f.setLocationRelativeTo(null);
        list1.setSize(250, 250);
        list1.setLocation(0, 0);
        next.setSize(75, 25);
        next.setLocation(251, 276);
    }

    public static void main(String[] args) {
        javax.swing.SwingUtilities.invokeLater(new Runnable() {
        public void run() {
        createAndShowGUI();
        }
        });
    }
}

Any ideas?

Thanks in advance!

Answer 1

This example puts the button below the list, and adds a border to the list using a scroll pane. 'White space' in the GUI is provided partly by spacing defined in the constructor of the layout (e.g. the space between list and button), and partly by using an EmptyBorder.

The control panel (which uses a BorderLayout) is then placed inside the other FlowLayout.

public class MTGSAMPServerReference extends JFrame implements ActionListener {

    public static Toolkit tk = Toolkit.getDefaultToolkit();
    static int ScrnWidth = ((int) tk.getScreenSize().getWidth());
    static int ScrnHeight = ((int) tk.getScreenSize().getHeight());

    private static final long serialVersionUID = 1L;
    private static JList list1;
    private static JButton next;

    public MTGSAMPServerReference() {
        // set flow layout for the frame
        this.getContentPane().setLayout(new FlowLayout(FlowLayout.LEADING));
        Object[] data1 = { "Value 1", "Value 2", "Value 3", "Value 4", "Value 5" };

        JPanel controls = new JPanel( new BorderLayout(5,5) );

        list1 = new JList<Object>(data1);
        list1.setVisibleRowCount(5);
        next = new JButton("Next");
        next.addActionListener(this);
        // add list to frame
        controls.add(new JScrollPane(list1));
        controls.add(next, BorderLayout.PAGE_END);
        // adjust numbers as needed.
        controls.setBorder(new EmptyBorder(25,25,0,0));

        add(controls);
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        if (e.getActionCommand().equals("Next")) {
            int index = list1.getSelectedIndex();
            System.out.println("Index Selected: " + index);
            String s = (String) list1.getSelectedValue();
            System.out.println("Value Selected: " + s);
        }
    }

    private static void createAndShowGUI() {
        //Create and set up the window.
        JFrame f = new MTGSAMPServerReference();
        //Display the window.
        f.pack();
        f.setVisible(true);
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        f.setSize(1200, 800);
        f.setLocationRelativeTo(null);
        list1.setSize(250, 250);
        list1.setLocation(0, 0);
        next.setSize(75, 25);
        next.setLocation(251, 276);
    }

    public static void main(String[] args) {
        javax.swing.SwingUtilities.invokeLater(new Runnable() {

If you want complete control over where the components are placed, and have setBounds work, you need to remove the layout manager. This can be done by setting the layout manager to null. That's not a good idea, though, and you are better off only using a layout manager and not using setBounds at all, because you are not tied down to a particular window size and default component sizes, and components that look good with a specific size on one look and feel might not look nice on another.
