flash.events.GesturePhase (ActionScript 3.0)

Package	flash.events
Class	public final class GesturePhase
Inheritance	GesturePhase Object

Language version:

ActionScript 3.0

Runtime version:

AIR 2

The GesturePhase class is an enumeration class of constant values for use with the GestureEvent, PressAndTapGestureEvent, and TransformGestureEvent classes. Use these values to track the beginning, progress, and end of a touch gesture (such as moving several fingers across a touch enabled screen) so your application can respond to individual stages of user contact. Some gestures (swipe and two-finger tap gestures) do not have multiple phases, and set the event object phase property to all.

	Property	Defined by
		constructor : Object A reference to the class object or constructor function for a given object instance.	Object
		prototype : Object [static] A reference to the prototype object of a class or function object.	Object

	Method		Defined by
		hasOwnProperty(name:String):Boolean Indicates whether an object has a specified property defined.	Object

		toLocaleString():String Returns the string representation of this object, formatted according to locale-specific conventions.	Object
		toString():String Returns the string representation of the specified object.	Object
		valueOf():Object Returns the primitive value of the specified object.	Object

	Constant	Defined by
		ALL : String = "all" [static] A single value that encompasses all phases of simple gestures like two-finger-tap or swipe.	GesturePhase
		BEGIN : String = "begin" [static] The beginning of a new gesture (such as touching a finger to a touch enabled screen).	GesturePhase
		END : String = "end" [static] The completion of a gesture (such as lifting a finger off a touch enabled screen).	GesturePhase
		UPDATE : String = "update" [static] The progress of a gesture (such as moving a finger across a touch enabled screen).	GesturePhase

Constant detail

ALL

constant

public static const ALL:String = "all"

Language version:

ActionScript 3.0

Runtime version:

AIR 2

A single value that encompasses all phases of simple gestures like two-finger-tap or swipe. For gestures that set the event object phase property to all (swipe and two-finger tap gestures), the phase value is always all once the event is dispatched.

BEGIN

constant

public static const BEGIN:String = "begin"

Language version:

ActionScript 3.0

Runtime version:

AIR 2

The beginning of a new gesture (such as touching a finger to a touch enabled screen).

END

constant

public static const END:String = "end"

Language version:

ActionScript 3.0

Runtime version:

AIR 2

The completion of a gesture (such as lifting a finger off a touch enabled screen).

UPDATE

constant

public static const UPDATE:String = "update"

Language version:

ActionScript 3.0

Runtime version:

AIR 2

The progress of a gesture (such as moving a finger across a touch enabled screen).

Examples

examples\TransformGestureEventExample

The following example shows event handling for the GESTURE_ROTATE events. While the user performs a rotation gesture on the touch-enabled device, mySprite rotates and myTextField populates with the current phase.

Multitouch.inputMode = MultitouchInputMode.GESTURE;

var mySprite = new Sprite();
mySprite.addEventListener(TransformGestureEvent.GESTURE_ROTATE , onRotate );
mySprite.graphics.beginFill(0x336699);
mySprite.graphics.drawRect(0, 0, 100, 80);
var myTextField = new TextField();
myTextField.y = 200;
addChild(mySprite);
addChild(myTextField);

function onRotate(evt:TransformGestureEvent):void {

    evt.target.rotation -= 45;

	if (evt.phase==GesturePhase.BEGIN) {
		myTextField.text = "Begin";
	}
	if (evt.phase==GesturePhase.UPDATE) {
		myTextField.text = "Update";
	}
	if (evt.phase==GesturePhase.END) {
		myTextField.text = "End";
	}
}
