Java GridLayout class

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.

GridLayout Source Code

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()); <font size=-1> frame.pack(); frame.setVisible(true); } public static void main(String[] args) { javax.swing.SwingUtilities.invokeLater(new Runnable() { public void run() { createAndShowGUI(); } }); } }
