I delete the code of "onUpAction" and "onMoveAction" in this way the code
become simpler...then, how you say, i remove Event listener but the the
problem is not solved:

private JButton getPolygonButton() {
                        if (polygonButton == null) {
                                polygonButton = new JButton();
                                polygonButton.setText("polygon");
                                polygonButton.addActionListener(new 
java.awt.event.ActionListener() {
                                        public void 
actionPerformed(java.awt.event.ActionEvent e) {     
                                                move = false;                   
                
                                                elem = 6;
                                                create = true;
                                                flag = true;
