How to use GridLayout

Java Swing Tutorial Explaining the GridLayout. GridLayout is a layout manager that lays out a container’s components in a rectangular grid. The container is divided into equal-sized rectangles, and one component is placed in each rectangle.

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

public class GridLayoutDemo {
public final static boolean RIGHT_TO_LEFT = false;

public static void addComponentsToPane(Container contentPane) {
if (RIGHT_TO_LEFT) {
contentPane.setComponentOrientation(
ComponentOrientation.RIGHT_TO_LEFT);
}
// Any number of rows and 2 columns
contentPane.setLayout(new GridLayout(0,2));

contentPane.add(new JLabel("JLabel 1"));
contentPane.add(new JButton("JButton 2"));
contentPane.add(new JCheckBox("JCheckBox 3"));
contentPane.add(new JTextField("Long-Named JTextField 4"));
contentPane.add(new JButton("JButton 5"));
}

private static void createAndShowGUI() {
JFrame.setDefaultLookAndFeelDecorated(true);

JFrame frame = new JFrame("GridLayout Source Demo");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

//Set up the content pane and components in GridLayout
addComponentsToPane(frame.getContentPane());
frame.pack();
frame.setVisible(true);
}

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