mwt
Interface EventListener

public interface EventListener

An event listener interface defines the method used to dispatch events.

Due to the small device's limitations, there is not an event listener hierarchy.
Instead, events are classified by an integer value.
Negative values are reserved for future MWT extensions and 0 is used for undefined event types.

Field Summary

static int	EVENT_ACTION Constant for action event types.
static int	EVENT_UNDEFINED Constant for undefined event types.

Method Summary

void	processEvent(int eventType, Component c, java.lang.Object[] args) Processes an event.

                  java.lang.Object[] args)

Parameters depend on how the caller invokes the event. However, the event type should be an EventListener EVENT_* constant (or any custom event type) and the component should be the sender.
