Constructor Detail

AbstractEventAdapter

public AbstractEventAdapter(UiFeatureEvent source,
                            UiHandlerEvent sender)

The constructor.

Parameters:

source - is the source of the events (typically UiWidget).

sender - is the sender of events (an adapter that delegates to the individual handlers/listeners).

Method Detail

fireEvent

public void fireEvent(EventType type)

Fires an event of the given EventType.

Parameters:

type - is the EventType to fire.

setProgrammaticEventType

public void setProgrammaticEventType(EventType type)

Parameters:

type - is the expected EventType used for detection to prevent concurrent user-events to interfere.
