mx.effects.Rotate (Flex™ 2 Language Reference

Package	mx.effects
Class	public class Rotate
Inheritance	Rotate TweenEffect Effect EventDispatcher Object

The Rotate effect rotates a component around a specified point. You can specify the coordinates of the center of the rotation, and the starting and ending angles of rotation. You can specify positive or negative values for the angles.

Note: To use the Rotate effect with text, you must use an embedded font, not a device font.

The <mx:Rotate> tag inherits all of the tag attributes of its superclass, and adds the following tag attributes:

  <mx:Rotate
    id="ID"
    angleFrom="0"
    angleTo="360"
    originX="0"
    originY="0"

	Method		Defined by
		Rotate(target:Object = null) Constructor.	Rotate
		addEventListener(type:String, listener:Function, useCapture:Boolean = false, priority:int = 0, useWeakReference:Boolean = false):void Registers an event listener object with an EventDispatcher object so that the listener receives notification of an event.	EventDispatcher
		captureStartValues():void Captures the current values of the relevant properties on the effect's targets.	Effect
		createInstance(target:Object = null):IEffectInstance Creates a single effect instance and initializes it.	Effect
		createInstances(targets:Array = null):Array Takes an Array of target objects and invokes the `createInstance()` method on each target.	Effect
		dispatchEvent(event:Event):Boolean Dispatches an event into the event flow.	EventDispatcher
		end(effectInstance:IEffectInstance = null):void Interrupts an effect that is currently playing, and jumps immediately to the end of the effect.	Effect
		getAffectedProperties():Array Returns an Array of Strings, where each String is the name of a property that is changed by this effect.	Effect
		hasEventListener(type:String):Boolean Checks whether the EventDispatcher object has any listeners registered for a specific type of event.	EventDispatcher
		pause():void Pauses the effect until you call the `resume()` method.	Effect
		play(targets:Array = null, playReversedFromEnd:Boolean = false):Array Begins playing the effect.	Effect
		removeEventListener(type:String, listener:Function, useCapture:Boolean = false):void Removes a listener from the EventDispatcher object.	EventDispatcher
		resume():void Resumes the effect after it has been paused by a call to the `pause()` method.	Effect
		reverse():void Plays the effect in reverse, if the effect is currently playing, starting from the current position of the effect.	Effect
		setPropertyIsEnumerable(name:String, isEnum:Boolean = true):void Sets the availability of a dynamic property for loop operations.	Object
		toString():String Returns the string representation of the specified object.	Object
		valueOf():Object Returns the primitive value of the specified object.	Object
		willTrigger(type:String):Boolean Checks whether an event listener is registered with this EventDispatcher object or any of its ancestors for the specified event type.	EventDispatcher

Property detail

angleFrom

property

public var angleFrom:Number = 0

The starting angle of rotation of the target object, expressed in degrees. Valid values range from 0 to 360.

The default value is 0.

angleTo

property

public var angleTo:Number = 360

The ending angle of rotation of the target object, expressed in degrees. Values can be either positive or negative.

If the value of angleTo is less than the value of angleFrom, the target rotates in a counterclockwise direction. Otherwise, it rotates in clockwise direction. If you want the target to rotate multiple times, set this value to a large positive or small negative number.

The default value is 360.

originX

property

public var originX:Number

The x-position of the center point of rotation. The target rotates around this point. The valid values are between 0 and the width of the target.

The default value is 0.

originY

property

public var originY:Number

The y-position of the center point of rotation. The target rotates around this point. The valid values are between 0 and the height of the target.

The default value is 0.

Constructor detail

Rotate

()

constructor

public function Rotate(target:Object = null)

Constructor.

Parameters

target:Object (default = null) — The Object to animate with this effect.
