Hi Ben,

I'm not sure if you are still in need of a solution to your problem but I would
recommend that you use the gwt-earth-3 project instead.
It provides full support for the entire Google Earth API, including the
capability that you are trying to implement.

You can find the project here:
https://code.google.com/p/gwt-earth-3/

Regards,
Nick
