How to set TabLayout Policy to JTabbedPane in Java when all the tabs does not fit in a single run

To set TabLayout Policy to JTabbedPane in Java when all the tabs does not fit in a single run, use the method setTabLayoutPolicy() −

JTabbedPane tabbedPane = new JTabbedPane();
tabbedPane.setTabLayoutPolicy(JTabbedPane.SCROLL_TAB_LAYOUT);

Above we have set the constant to be SCROLL_TAB_LAYOUT, which is a tab layout policy for providing a subset of available tabs when all the tabs will not fit within a single run.

The following is an example −

package my;
import javax.swing.*;
import java.awt.*;
import java.awt.event.KeyEvent;
public class SwingDemo {
   public static void main(String args[]) {
      JFrame frame = new JFrame("Devices");
      JTabbedPane tabbedPane = new JTabbedPane();
      JPanel panel1, panel2, panel3, panel4, panel5, panel6, panel7, panel8;
      panel1 = new JPanel();
      panel2 = new JPanel();
      panel3 = new JPanel();
      panel4 = new JPanel();
      panel5 = new JPanel();
      panel6 = new JPanel();
      panel7 = new JPanel();
      panel8 = new JPanel();
      tabbedPane.setBackground(Color.blue);
      tabbedPane.setForeground(Color.white);
      tabbedPane.setTabLayoutPolicy(JTabbedPane.SCROLL_TAB_LAYOUT);
      tabbedPane.addTab("Laptop", panel1);
      tabbedPane.addTab("Desktop ", panel2);
      tabbedPane.addTab("Notebook", panel3);
      tabbedPane.addTab("Echo ", panel4);
      tabbedPane.addTab("Tablet", panel5);
      tabbedPane.addTab("Alexa ", panel6);
      tabbedPane.addTab("Notebook", panel7);
      tabbedPane.addTab("iPad", panel8);
      frame.add(tabbedPane);
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      frame.setSize(500,350);
      frame.setVisible(true);
   }
}

The output is as follows. Now you can see all the tabs does not fit, therefore a navigation is visible to display all other tabs on the right −

Now when you will click on the right navigation, all the other tabs will be visible −
