推荐答案

来自 MouseListener 可以执行的方法：

From MouseListener methods you can do:

@Override
public void mouseClicked(MouseEvent e) {
    int x=e.getX();
    int y=e.getY();
    System.out.println(x+","+y);//these co-ords are relative to the component
}

只需将其添加到组件中：

component.addMouseListener(new MouseListener() {
    @Override
    public void mouseClicked(MouseEvent e) {
    }
});
