Screen.navigationClick(int, int) or Screen.navigationMovement(int, int, int, int) instead.
NOTE: Use of this interface is strongly discouraged.
A listener interface for receiving trackwheel events.
Instead of using this interface, developers are strongly encouraged to use the
"navigation" methods in the Screen class to receive such notifications. This is
done by extending the Screen class and providing custom implementations of the
following 3 methods:
Screen.navigationClick(int, int)Screen.navigationUnclick(int, int)Screen.navigationMovement(int, int, int, int)
