Method Detail

appendback to summary
public EventDispatchTree append(final EventDispatcher eventDispatcher)

Implements com.sun.javafx.event.EventDispatchTree.append.

Doc from javafx.event.EventDispatchChain.append.

Appends the specified EventDispatcher to this chain. Returns a reference to the chain with the appended element.

The caller shouldn't assume that this EventDispatchChain remains unchanged nor that the returned value will reference a different chain after the call. All this depends on the EventDispatchChain implementation.

So the call should be always done in the following form: chain = chain.append(eventDispatcher);

Parameters
eventDispatcher:EventDispatcher

the EventDispatcher to append to the chain

Returns:EventDispatchTree

the chain with the appended event dispatcher

dispatchEventback to summary
public Event dispatchEvent(final Event event)

Implements javafx.event.EventDispatchChain.dispatchEvent.

Doc from javafx.event.EventDispatchChain.dispatchEvent.

Dispatches the specified event through this EventDispatchChain. The return value represents the event after processing done by the chain. If further processing is to be done after the call the event referenced by the return value should be used instead of the original event. In the case the event is fully handled / consumed in the chain the returned value is null and no further processing should be done with that event.

Parameters
event:Event

the event to dispatch

Returns:Event

the processed event or null if the event had been fully handled / consumed

public EventDispatchTree prepend(final EventDispatcher eventDispatcher)

Implements com.sun.javafx.event.EventDispatchTree.prepend.

Doc from javafx.event.EventDispatchChain.prepend.

Prepends the specified EventDispatcher to this chain. Returns a reference to the chain with the prepended element.

The caller shouldn't assume that this EventDispatchChain remains unchanged nor that the returned value will reference a different chain after the call. All this depends on the EventDispatchChain implementation.

So the call should be always done in the following form: chain = chain.prepend(eventDispatcher);

Parameters
eventDispatcher:EventDispatcher

the EventDispatcher to prepend to the chain

Returns:EventDispatchTree

the chain with the prepended event dispatcher

public String toString()

Overrides java.lang.Object.toString.

Doc from java.lang.Object.toString.

Returns a string representation of the object. Satisfying this method's contract implies a non-null result must be returned.

Returns:String

a string representation of the object
