A PopupMenu is a setting menu that appears when you right-click on a component, such as a button or a venire. It provides a set of options or actions that the user can select from. In this clause, we testament explore the syntax, methods, and constructors of the Java AWT PopupMenu.

Example of Java AWT PopupMenu

Below is the implementation of Java AWT PopupMenu:

Java

// Java Program to implement
// Java AWT PopupMenu
import java.awt.*;
import java.awt.event.*;

// Driver Class
public class PopupMenuExample {
      // main function
    public static void main(String[] args) {

        Frame frame = new Frame("GeeksforGeeks PopupMenu Example");
        frame.setSize(400, 400);

        // Create a PopupMenu
        PopupMenu popupMenu = new PopupMenu();

        // Create MenuItems
        MenuItem menuItem1 = new MenuItem("Option 1");
        MenuItem menuItem2 = new MenuItem("Option 2");
        MenuItem menuItem3 = new MenuItem("Option 3");

        // Add MenuItems to the PopupMenu
        popupMenu.add(menuItem1);
        popupMenu.add(menuItem2);
        popupMenu.add(menuItem3);

        // Add the PopupMenu to the Frame
        frame.add(popupMenu);

        // Add a MouseListener to the Frame to display the PopupMenu
        frame.addMouseListener(new MouseAdapter() {
            public void mousePressed(MouseEvent e) {
                if (e.isPopupTrigger()) {
                    popupMenu.show(frame, e.getX(), e.getY());
                }
            }

            public void mouseReleased(MouseEvent e) {
                if (e.isPopupTrigger()) {
                    popupMenu.show(frame, e.getX(), e.getY());
                }
            }
        });

        frame.setLayout(null);
        frame.setVisible(true);

    }
}
