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
, TouchEvent
, FocusEvent
, KeyboardEvent
, WheelEvent
, InputEvent
, and CompositionEvent
.
Constructors
UIEvent()
- Creates a
UIEvent
object.

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.detail
Read only- Returns a
long

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

UIEvent.pageX
Read only- Returns the horizontal coordinate of the event relative to the whole document.
UIEvent.pageY

UIEvent.sourceCapabilities
