Hi,

Is it possible to show popup menu by right click our mouse(by using PApplet & if yes, then how) ?

Create a JPopupMenu in method setup() as follows:

import javax.swing.*;
import java.awt.event.*;

void setup() {

final JPopupMenu menu = new JPopupMenu();
   
   // Create and add a menu item
   JMenuItem item = new JMenuItem("Item Label 1");
   item.addActionListener(new ActionListener() {
       void actionPerformed(ActionEvent e) {
           System.out.println("Item Label 1");
       }
   });
   menu.add(item);
   item = new JMenuItem("Item Label 2");
   menu.add(item);
   
   // Set the component to show the popup menu
   addMouseListener(new MouseAdapter() {        
       public void mouseReleased(MouseEvent evt) {
           if (evt.isPopupTrigger()) {
               menu.show(evt.getComponent(), evt.getX(), evt.getY());
           }
       }
   });
}
