Hi Ian,
There's a better way to do what you want to do, but I'm not sure what
you want to do. Do you want to do anything in particular with the
mouse events, or how to interact with OMGraphics on your layer? You
get a lot of help doing this if your overlay layer extends
OMGraphicHandlerLayer. If you are extending OMGraphicHandlerLayer and
want events to fall through to other layers, set the consumeEvents
flag to false on your layer.
If you want to interact with the OMGraphics on your layer, I suggest
taking a look at the code for the
com.bbn.openmap.layer.learn.InteractionLayer. There are comments in
the code explaining all the different aspects of receiving and
managing MouseEvents with the current MapMouseModes.
If you want to do something else, or have question about that layer or
your layer, let me know. If you have more specifics that'll help,
too.
Cheers,
Don
