Interface CommandListener

public interface CommandListener

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.

Since:

MIDP 1.0
