JMapViewer将鼠标侦听器添加到MapMarkerDot

Question

I am trying to add a mouse listener to a MapMarker, so that when a mouse will hover a MapMarker, I could react with an event.

I implemented the mouseListener, but I can't really add a listener. The issue is that I did not find a way the MapMarker will addMouseListener, due to the fact that non of the hierarchy implements JPanel.

Any help appreciated

As noted here , the default JMapViewer constructor uses a DefaultMapController , "which implements map moving by pressing the right mouse button and zooming by double click or by mouse wheel." To see map coordinates, extend DefaultMapController , override mouseClicked() and use one of the viewer's getPosition() methods. You can use your controller as shown in comments at line 65 of Demo.java , r30377.

 new DefaultMapController(map){

    @Override
    public void mouseClicked(MouseEvent e) {
        System.out.println(map.getPosition(e.getPoint()));
    }
};
