Method Detail

cameraMoved

void cameraMoved(Camera cam,
                 Point2D.Double coord,
                 double alt)

Called back when a Camera is moved. Callback handlers are expected to be thread-safe. Do not perform blocking or time consuming tasks within the handler. It is a bad idea to move the target Camera in a handler (infinite loop). Moving other Cameras is also probably a bad idea. To receive notifications, clients should register themselves using Camera.addListener

Parameters:

cam - camera which was moved

coord - camera xy coordinates after the move

alt - camera altitude after the move
