The UIEvent interface represents simple user interface events.

UIEvent derives from Event. Although the UIEvent.initUIEvent() method is kept for backward compatibility, you should create a UIEvent object using the UIEvent() constructor.

Several interfaces are direct or indirect descendants of this one: MouseEvent, TouchEventFocusEvent, KeyboardEvent, WheelEvent, InputEvent, and CompositionEvent.

Constructors

UIEvent()
Creates a UIEvent object.

Properties

This interface also inherits properties of its parent, Event.

UIEvent.cancelBubble  
Is a Boolean indicating whether the bubbling of the event has been canceled or not.
UIEvent.detailRead only
Returns a long with details about the event, depending on the event type.
UIEvent.isChar Read only
Returns a Boolean indicating whether the event produced a key character or not.
UIEvent.layerX Read only
Returns the horizontal coordinate of the event relative to the current layer.
UIEvent.layerY Read only

UIEvent.pageY Read only
