Static Properties

final DomEventType<BlurHandler> TYPE #

Event type for focus events. Represents the meta-data associated with this event.

static final DomEventType<BlurHandler> TYPE = new DomEventType<BlurHandler>(BrowserEvents.BLUR, new BlurEvent())

Constructors

new BlurEvent() #

Protected constructor, use {@link DomEvent#fireNativeEvent(com.google.gwt.dom.client.NativeEvent, com.google.gwt.event.shared.HasHandlers)} to fire focus events.

BlurEvent();

Methods

void assertLive() #

inherited from DwtEvent

Asserts that the event still should be accessed. All events are considered to be "dead" after their original handler manager finishes firing them. An event can be revived by calling {@link GwtEvent#revive()}.

void assertLive() {
 assert (!_dead) ; //: "This event has already finished being processed by its original handler manager, so you can no longer access it";
}

void dispatch(BlurHandler handler) #

Implemented by subclasses to invoke their handlers in a type safe manner. Intended to be called by EventBus#fireEvent(Event) or EventBus#fireEventFromSource(Event, Object).

@param handler handler @see EventBus#dispatchEvent(Event, Object)

docs inherited from IEvent<H>

void dispatch(BlurHandler handler) {
 handler.onBlur(this);
}

DomEventType<BlurHandler> getAssociatedType() #

Returns the EventType used to register this event, allowing an EventBus to find handlers of the appropriate class.

@return the type

docs inherited from IEvent<H>

DomEventType<BlurHandler> getAssociatedType() {
 return TYPE;
}

Event getNativeEvent() #

inherited from DomEvent

Gets the underlying native event.

@return the native event

docs inherited from HasNativeEvent

dart_html.Event getNativeEvent() {
 assertLive();
 return _nativeEvent;
}

Element getRelativeElement() #

inherited from DomEvent

Gets the element relative to which event coordinates will be measured. If this element is <code>null</code>, event coordinates will be measured relative to the window's client area.

@return the event's relative element

dart_html.Element getRelativeElement() {
 assertLive();
 return _relativeElem;
}

Object getSource() #

inherited from DwtEvent

Returns the source for this event. The type and meaning of the source is arbitrary, and is most useful as a secondary key for handler registration. (See EventBus#addHandlerToSource, which allows a handler to register for events of a particular type, tied to a particular source.)

Note that the source is actually set at dispatch time, e.g. via EventBus#fireEventFromSource(Event, Object).

@return object representing the source of this event

docs inherited from IEvent<H>

Object getSource() {
 assertLive();
 return super.getSource();
}

bool isLive() #

inherited from DwtEvent

Is the event current live?

@return whether the event is live

bool isLive() {
 return !_dead;
}

void kill() #

inherited from DwtEvent

Kill the event. After the event has been killed, users cannot really on its values or functions being available.

void kill() {
 _dead = true;
 setSource(null);
}

void overrideSource(Object source) #

inherited from DwtEvent

void overrideSource(Object source) {
 super.setSource(source);
}

void preventDefault() #

inherited from DomEvent

Prevents the wrapped native event's default action.

void preventDefault() {
 assertLive();
 _nativeEvent.preventDefault();
}

void revive() #

inherited from DwtEvent

Revives the event. Used when recycling event instances.

void revive() {
 _dead = false;
 setSource(null);
}

void setSource(source) #

inherited from IEvent

Set the source that triggered this event. Intended to be called by the EventBus during dispatch.

@param source the source of this event. @see EventBus#fireEventFromSource(Event, Object) @see EventBus#setSourceOfEvent(Event, Object)

void setSource(dynamic source) {
 this._source = source;
}

void stopPropagation() #

inherited from DomEvent

Stops the propagation of the underlying native event.

void stopPropagation() {
 assertLive();
 _nativeEvent.stopPropagation();
}

String toString() #

inherited from IEvent

The toString() for abstract event is overridden to avoid accidently including class literals in the the compiled output. Use Event

toDebugString to get more information about the event.

String toString() {
 return "An event type";
}
