How can we set the foreground and background color to JComboBox items in Java?
A JComboBox is a subclass of JComponent class and it is a combination of a text field and a drop-down list from which the user can choose a value. A JComboBox can generate an ActionListener, ChangeListener and ItemListener interfaces when the user actions on a combo box. We can also set the foreground and background color to JComboBox items by using setForeground() and setBackground() methods of a JComboBox class.
Example
import java.awt.*;
import javax.swing.*;
public class JComboBoxItemColorTest extends JFrame{
private JComboBox jcb;
public JComboBoxItemColorTest() {
setTitle("JComboBoxItemColor Test");
String[] countries = {"India", "Australia", "England", "South Africa", "Newzealand"};
jcb = new JComboBox(countries);
jcb.setForeground(Color.blue);
jcb.setBackground(Color.white);
add(jcb, BorderLayout.NORTH);
setSize(500,300);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setLocationRelativeTo(null);
setVisible(true);
}
public static void main(String[]args) {
new JComboBoxItemColorTest();
}
}Output
