How can we add different font style items to JList in Java?
A JList is a subclass of JComponent class and it can be used to display a list of objects that allows the user to select one or more items. A JList can generate a ListSelectiionListener interface and need to implement the abstract method valueChanged(). A DefaultListModel class provides a simple implementation of a list model, which can be used to manage items displayed by a JList control. We can add the items to a JList using the addElement() method of the DefaultListModel class, we can also add items with different fonts to JList using HTML tags like <b> for bold style text, <i> for italic style text, <u> for underlined style text etc.
Example
import java.awt.*;
import javax.swing.*;
public class JLabelListTest {
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
new JLabelListTest().makeUI();
}
});
}
public void makeUI() {
String[] data = {"<html>Raja</html>", "<html><b>Adithya</b></html>", "<html><i>Jaidev</i> </html>", "<html><u>Chaitanya</u></html>"};
JList list = new JList(data);
list.setBackground(Color.lightGray);
JFrame frame = new JFrame();
frame.getContentPane().add(new JScrollPane(list), BorderLayout.NORTH);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(400, 300);
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
}Output
