I want to add a mousse listener to this polygon. How can I add mouse listener to graphics Polygon?

public class Domx extends JPanel{

    Domx(){
    }

    @Override

        super.paintComponent(g);
        Graphics2D g2 = (Graphics2D) g;
        this.setBackground(Color.white);
        Polygon p4=new Polygon();
        for (int i = -1; i < 2; i++) {
                p4.addPoint((int) (X + i * P4[9] / 2), (int) (Y + P1[10] + P2[10] + P3[10] + P4[10]));
        }
        for (int i = 1; i > -2; i--) {
            p4.addPoint((int) (X + i * P4[8] / 2), (int) (Y + P1[10] + P2[10] + P3[10]));

A MouseListener is added to components, which a Polygon is .. not. Instead add the mouse listener to the component which displays it, then when a mouse action happens, check if polygon.contains(..) before proceeding.
