Method Detail

    public static GwtEvent.Type<Event.NativePreviewHandler> getType()

  Gets the type associated with this event.

  Returns:
    returns the handler type

### cancel

    public void cancel()

  Cancel the native event and prevent it from firing. Note that the event can still fire if another handler calls `consume()`. Classes overriding this method should still call super.cancel().

### consume

    public void consume()

  Consume the native event and prevent it from being canceled, even if it has already been canceled by another handler. `Event.NativePreviewHandler` that fire first have priority over later handlers, so all handlers should check if the event has already been canceled before calling this method.

### getAssociatedType

    public final GwtEvent.Type<Event.NativePreviewHandler> getAssociatedType()

  Description copied from class: `Event`
  Returns the `Event.Type` used to register this event, allowing an `EventBus` to find handlers of the appropriate class.

  Specified by:
    `getAssociatedType` in class `GwtEvent<Event.NativePreviewHandler>`
  Returns:
    the type

### getNativeEvent

    public NativeEvent getNativeEvent()

  Description copied from interface: `HasNativeEvent`
  Gets the underlying native event.

  Specified by:
    `getNativeEvent` in interface `HasNativeEvent`
  Returns:
    the native event

### getTypeInt

    public final int getTypeInt()

  Gets the type int corresponding to the native event that triggered this preview.

  Returns:
    the type int associated with this native event

### isCanceled

    public boolean isCanceled()

  Has the event already been canceled? Note that `isConsumed()` will still return true if the native event has also been consumed.

  Returns:
    true if the event has been canceled
  See Also:

### isConsumed

    public boolean isConsumed()

  Has the native event been consumed? Note that `isCanceled()` will still return true if the native event has also been canceled.

  Returns:
    true if the event has been consumed
  See Also:

### isFirstHandler

    public boolean isFirstHandler()

  Is the current handler the first to preview this event?

  Returns:
    true if the current handler is the first to preview the event

### dispatch

    protected void dispatch(Event.NativePreviewHandler handler)
