How to create a Box to display components from left to right in Java

Box is lightweight container that uses a BoxLayout object as its layout manager. To display components from left to right, use Box createHorizontalBox() method.

Let us first create some button components −

JButton button1 = new JButton("One"); JButton button2 = new JButton("Two"); JButton button3 = new JButton("Three"); JButton button4 = new JButton("Four"); JButton button5 = new JButton("Five"); JButton button6 = new JButton("Six");

Now, crate a Box and align all the buttons from left to right −

Box box = Box.createHorizontalBox(); box.add(button1); box.add(button2); box.add(button3); box.add(button4); box.add(button5); box.add(button6);

The following is an example to create a Box to display components from left to right −

Example

package my; import java.awt.BorderLayout; import javax.swing.Box; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JScrollPane; public class SwingDemo {    public static void main(String args[]) {       JFrame frame = new JFrame("Demo");       frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);       JButton button1 = new JButton("One");       JButton button2 = new JButton("Two");       JButton button3 = new JButton("Three");       JButton button4 = new JButton("Four");       JButton button5 = new JButton("Five");       JButton button6 = new JButton("Six");       Box box = Box.createHorizontalBox();       box.add(button1);       box.add(button2);       box.add(button3);       box.add(button4);       box.add(button5);       box.add(button6);       JScrollPane jScrollPane = new JScrollPane();       jScrollPane.setViewportView(box);       frame.add(jScrollPane, BorderLayout.CENTER);       frame.setSize(550, 250);       frame.setVisible(true);    } }

This will produce the following output −
