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 −
