Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1


Starting with Flex 4.0, Apache recommends that you use the spark.effects.Rotate class as an alternative to this class.

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.

MXML SyntaxexpandedHide MXML Syntax

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"
  />

Property Detail
angleFromproperty
public var angleFrom:Number = 0

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

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

The default value is 0.

angleToproperty 
public var angleTo:Number = 360

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

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.

hideFocusRingproperty 
hideFocusRing:Boolean[override]

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

Determines whether the effect should hide the focus ring when starting the effect. The target itself is responsible for the actual hiding of the focus ring.

The default value is true.

    public function get hideFocusRing():Boolean
    public function set hideFocusRing(value:Boolean):void

The default value is 0.

originYproperty 
public var originY:Number

Language Version : ActionScript 3.0
