Interface TouchEvent

All Superinterfaces:

Event, UIEvent

All Known Implementing Classes:

JsTouchEvent

public interface TouchEvent
extends UIEvent

A TouchEvent represents an event sent when the state of contacts with a touch-sensitive surface changes. This surface can be a touch screen or trackpad, for example. The event can describe one or more points of contact with the screen and includes support for detecting movement, addition and removal of contact points, and so forth.

Touches are represented by the Touch object; each touch is described by a position, size and shape, amount of pressure, and target element. Lists of touches are represented by TouchList objects.

Method Summary

Modifier and Type	Method and Description
TouchList	getChangedTouches() A TouchList of all the Touch objects representing individual points of contact whose states changed between the previous touch event and this one.
TouchList	getTargetTouches() A TouchList of all the Touch objects that are both currently in contact with the touch surface and were also started on the same element that is the target of the event.
TouchList	getTouches() A TouchList of all the Touch objects representing all current points of contact with the surface, regardless of target or changed status.

boolean	isAltKey() A Boolean value indicating whether or not the alt key was down when the touch event was fired.
boolean	isCtrlKey() A Boolean value indicating whether or not the control key was down when the touch event was fired.
boolean	isMetaKey() A Boolean value indicating whether or not the meta key was down when the touch event was fired.
