Constructor Detail

HeadsUpDisplay

HeadsUpDisplay(PolltrackV trackV,
              Spool spool)

Creates a HeadsUpDisplay. Create at most one for the entire life of the trackV registry, as currently it does not unregister its listeners there.

Parameters:

spool - the spool for the release of associated holds. When unwound it releases the holds of this display and thereby disables it.
