Class | public class TouchEvent |
Inheritance | TouchEvent Event Object |
Language version: | ActionScript 3.0 |
Runtime version: | AIR 2 |
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.)

, and touchRollOver
events.
The value of this property can be null
in two circumstances: if there is no related object,

relatedObject:InteractiveObject (default = null ) — The complementary InteractiveObject instance that is affected by the event. For example, when a touchOut event occurs,
relatedObject represents the display list object to which the pointing device now points.
|
|
ctrlKey:Boolean (default = false ) — On Windows or Linux, indicates whether the Ctrl key is activated. On Mac, indicates whether either the Ctrl key or the Command key is activated.
|
|
altKey:Boolean (default = false ) — Indicates whether the Alt key is activated (Windows or Linux only).
|
|
shiftKey:Boolean (default = false ) — Indicates whether the Shift key is activated.
|
|
commandKey:Boolean (default = false ) — (AIR only) Indicates whether the Command key is activated (Mac only). This parameter is for Adobe AIR only; do not set it for Flash Player content.
|
|
controlKey:Boolean (default = false ) — (AIR only) Indicates whether the Control or Ctrl key is activated. This parameter is for Adobe AIR only; do not set it for Flash Player content.
|
|
timestamp:Number — (AIR only) The timestamp of the event in milliseconds relative to the start of the application.
|
|
touchIntent:String — (AIR only) A value from the TouchEventIntent class.
|
|
samples:ByteArray (default = null ) — (AIR only) A ByteArray object containing position and pressure readings for each intermediate sample
recorded since the last touch or proximity event in a sequence.
|
|
isTouchPointCanceled:Boolean (default = false ) — (AIR only) true if the touch event is canceled because of a rejected touch type.
|
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.
ReturnsEvent —
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.
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.
|
uint —
uint the number of samples added to the buffer. Each sample consists of three floating point Numbers.

stageY | The vertical coordinate at which the event occurred in global stage coordinates. |

TOUCH_ROLL_OUT | constant |
public static const TOUCH_ROLL_OUT:String = "touchRollOut"
Language version: | ActionScript 3.0 |
Runtime version: | AIR 2 |
Defines the value of the type
property of a TOUCH_ROLL_OUT
touch event object.
The dispatched TouchEvent object has the following properties:
Property | Value |
---|---|
altKey | true if the Alt key is active (Windows or Linux). |
bubbles | true |
cancelable | false ; there is no default behavior to cancel. |
commandKey | true on the Mac if the Command key is active; false if it is inactive. Always false on Windows. |

localY | The vertical coordinate at which the event occurred relative to the containing sprite. |
pressure | A value between 0.0 and 1.0 indicating force of the contact with the device. If the device does not support detecting the pressure, the value is 1.0 . |

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"); }
Multitouch.maxTouchPoints
and the
touch event object's touchPointID
properties.
