public Main() {
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
addMouseListener(getListener());
setSize(200, 200);
pane = (JPanel) getContentPane();
setVisible(true);
}
private MouseListener getListener() {
return new MouseAdapter() {
@Override
public void mousePressed(MouseEvent e) {
super.mousePressed(e);
pane.setCursor(Cursor.getPredefinedCursor(Cursor.CROSSHAIR_CURSOR));
}
@Override
public void mouseReleased(MouseEvent e) {
super.mouseReleased(e);
pane.setCursor(Cursor.getDefaultCursor());
}
};
