spark.effects.Rotate (Flex 4 Beta)

Package	spark.effects
Class	public class Rotate
Inheritance	Rotate AnimateTransform Animate Effect EventDispatcher Object

Language Version:

ActionScript 3.0

Product Version:

Flex 4

Runtime Versions:

Flash Player 10, AIR 1.5

The Rotate effect rotates a target object in the x, y plane around the transform center.

If you specify any two of the angle values (angleFrom, angleTo, or angleBy), Flex calculates the third. If you specify all three, Flex ignores the angleBy value.

Like all AnimateTransform-based effects, this effect will only work on subclasses of UIComponent and GraphicElement, as these effects depend on specific transform functions in those classes.

	Property	Defined By
		applyTransitionEndProperties : Boolean This flag controls whether the effect, when run in a transition, will automatically apply the property values according to the end state, as opposed to leaving values as set by the effect itself.	Effect
		endValuesCaptured : Boolean = false A flag containing true if the end values of an effect have already been determined, or false if they should be acquired from the current properties of the effect targets when the effect runs.	Effect

ActionScript 3.0

Product Version:

Flex 4

Runtime Versions:

Flash Player 10, AIR 1.5

Degrees by which to rotate the target object. Value may be negative.

If the value of angleBy is negative, 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.

angleFrom

property

public var angleFrom:Number

Language Version:

ActionScript 3.0

Product Version:

Flex 4

Runtime Versions:

Flash Player 10, AIR 1.5

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

angleTo

public var angleTo:Number

Language Version:

ActionScript 3.0

Product Version:

Flex 4

Runtime Versions:

Flash Player 10, AIR 1.5

The ending angle of rotation of the target object, 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.
