[OpenMap Users] Implementing a Layer that Hijacks Mouse Clicks

Hi,

I am attempting to create an OpenMap layer that handles mouse events internally.

OpenMap's Layer.addMouseListener() method prevents me from attaching my own mouse listener as it rejects any listener that isn't part of javax.swing. The Javadoc helpfully points out that this is to stop classes stealing the mouse events and thus not letting them fall through to the map.

However, that's exactly what I want to do. My "overlay"-type layer gets switched on and off, but when it's on, it sits on top and steals mouse clicks to handle them itself rather than passing them through to the layers below.

Can I only do this by overriding OpenMap's Layer class to remove the check, or is there a better way to do what I'm trying to do?

Thanks,

Ian
