Re: How to align swing buttons vertically ?

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

public class test extends JPanel {
    public test() {
        super(new GridBagLayout());

        GridBagConstraints c = new GridBagConstraints();
        c.fill = GridBagConstraints.HORIZONTAL;
        c.gridy = 0;

        String labels[] = {"Button 1","Button 2",
         "Long Button 3","Button 4","Button 5"};

        for (int i=0; i<labels.length; i++) {
            add(new JButton(labels[i]),c);
            ++c.gridy;
        }
    }

    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {
            public void run() {
                JFrame f = new JFrame();
                f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                f.add(new test(),BorderLayout.EAST);
                f.setSize(700,500);
                f.setVisible(true);
            }
        });
    }
