| CommandListener | | public interface CommandListener (Code) | | This interface is used by applications which need to receive
high-level events from the implementation. An application will
provide an implementation of a CommandListener
(typically by using
a nested class or an inner class) and will then provide the
instance to the addCommand method on a
Displayable in
order to receive high-level events on that screen.
The specification does not require the platform to create several
threads for the event delivery.
Thus, if a CommandListener method does not return
or the return is
not delayed, the system may be blocked. So, there is the following note to
application developers:
- the
CommandListener method should return
immediately.
