Classpublic class TouchEvent
InheritanceTouchEvent Inheritance Event Inheritance Object

Language version: ActionScript 3.0
Runtime version: AIR 2

The TouchEvent class lets you handle events on devices that detect user contact with the device (such as a finger on a touch screen).

When a user interacts with a device such as a mobile phone or tablet with a touch screen, the user typically touches the screen with his or her fingers or a pointing device. You can develop applications that respond to basic touch events (such as a single finger tap) with the TouchEvent class. Create event listeners using the event types defined in this class. For user interaction with multiple points of contact (such as several fingers moving across a touch screen at the same time) use the related GestureEvent, PressAndTapGestureEvent, and TransformGestureEvent classes. And, use the properties and methods of these classes to construct event handlers that respond to the user touching the device.

Use the Multitouch class to determine the current environment's support for touch interaction, and to manage the support of touch interaction if the current environment supports it.

Note: When objects are nested on the display list, touch events target the deepest possible nested object that is visible in the display list. This object is called the target node. To have a target node's ancestor (an object containing the target node in the display list) receive notification of a touch event, use EventDispatcher.addEventListener() on the ancestor node with the type parameter set to the specific touch event you want to detect.

In AIR 3, and above, you can listen for proximity events on supported Android devices that have an active stylus. On such devices, proximityMove and touchMove event objects provide a byte array containing path and pressure samples taken since the previous move event. You can use these samples to construct the path of the stylus between touch events. (Note that hit-testing for interaction of the stylus input with the display list only occurs at the end of a path segment.)

A unique identification number (as an int) assigned to the touch point.

Implementation
    public function get touchPointID():int
    public function set touchPointID(value:int):void

Example
The following example establishes a variable touchMoveID to test for the correct touchPointID value before responding to a touch move event. Otherwise, other touch input triggers the event handler, too. Notice the listeners for the move and end phases are on the stage, not the display object. The stage listens for the move or end phases in case the user's touch moves beyond the display object boundaries.

Method detail
clone()method
public override function clone():Event

Language version: ActionScript 3.0
Runtime version: AIR 2

Creates a copy of the TouchEvent object and sets the value of each property to match that of the original.

Returns
Event — A new TouchEvent object with property values that match those of the original.
getSamples()method 
public function getSamples(buffer:ByteArray, append:Boolean = false):uint

Language version: ActionScript 3.0
Runtime version: AIR 3

Updates the specified ByteArray object with the high-frequency data points for a multi-point touch event.

The ByteArray object referenced by the buffer parameter is updated with values for the intermediate data points between this and the previous touch event. Three floating point values are added for each sample: an x coordinate, a y coordinate, and a pressure value. The position values reported in stage coordinates. The pressure is reported as a value between 0 and 1. Samples are recorded at regular time intervals. The exact frequency depends on the device hardware and hardware drivers. Typical sample frequencies are around 133 Hz. Note that touch events are not dispatched at exact intervals. Thus, the buffer for similar events can contain a different number of samples. The last sample in the buffer has the same data as the stageX, stageY, and pressure properties of this touch event object.

A sample buffer is included in the event objects dispatched for proximityMove and touchMove events.

Parameters
buffer:ByteArray — the ByteArray object to receive the sample data.
 
append:Boolean (default = false) — when true, the samples are added to the buffer byte array starting at the array's current position property. When false, the default, existing data in the buffer object is discarded before the samples are added.

Returns
uint — uint the number of samples added to the buffer. Each sample consists of three floating point Numbers.

Defines the value of the type property of a TOUCH_TAP touch event object.

The dispatched TouchEvent object has the following properties:

PropertyValue
altKeytrue if the Alt key is active (Windows or Linux).
bubblestrue

Example
The following example displays a message when the square drawn on mySprite is tapped on a touch-enabled screen:
Multitouch.inputMode=MultitouchInputMode.TOUCH_POINT;

var mySprite:Sprite = new Sprite();
var myTextField:TextField = new TextField();

mySprite.graphics.beginFill(0x336699);
mySprite.graphics.drawRect(0,0,40,40);
addChild(mySprite);

mySprite.addEventListener(TouchEvent.TOUCH_TAP, taphandler);

function taphandler(e:TouchEvent): void {
    myTextField.text = "I've been tapped";
	myTextField.y = 50;
	addChild(myTextField);
}

Examples
examples\TouchEventExample
The following example shows event handling for the TOUCH_BEGIN, TOUCH_MOVE, and TOUCH_END events. While the point of contact moves across the screen (onTouchMove), the x-coordinate relative to the stage is traced to output. For the Sprite.startTouchDrag parameters in the onTouchBegin function, the value for touchPointID is the value assigned to the event object. The bounds parameter is the rectangle defining the boundaries of the parent display object (bg is a display object containing MySprite).
Multitouch.inputMode = MultitouchInputMode.TOUCH_POINT;

MySprite.addEventListener(TouchEvent.TOUCH_BEGIN, onTouchBegin);
MySprite.addEventListener(TouchEvent.TOUCH_MOVE, onTouchMove);
MySprite.addEventListener(TouchEvent.TOUCH_END, onTouchEnd);

function onTouchBegin(eBegin:TouchEvent) {
     eBegin.target.startTouchDrag(eBegin.touchPointID, false, bg.getRect(this));
 	trace("touch begin");
 
 }

function onTouchMove(eMove:TouchEvent) {
	trace(eMove.stageX);
}
 
function onTouchEnd(eEnd:TouchEvent) {
 	eEnd.target.stopTouchDrag(eEnd.touchPointID);
 	trace("touch end");
}
examples\TouchExample2
The following example shows how to handle touch events and touch event phases, as well as the Multitouch.maxTouchPoints and the touch event object's touchPointID properties. This example comes from Christian Cantrell, and is explained in more detail in his quickstart: Multi-touch and gesture support on the Flash Platform.
