Property Detail

angle

property
angle:Number
Deprecated: Please Use rotation

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

By default, the LinearGradientStroke defines a transition from left to right across the control. Use the angle property to control the transition direction. For example, a value of 180.0 causes the transition to occur from right to left, rather than from left to right.

The default value is 0.0.



Implementation
    public function get angle():Number
    public function set angle(value:Number):void

compoundTransform

property 
protected var compoundTransform:mx.geom:CompoundTransform

Holds the matrix and the convenience transform properties (x, y, and rotation). The compoundTransform is only created when the matrix property is set.

entries

property 
entries:Array

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

An Array of GradientEntry objects defining the fill patterns for the gradient fill.

The default value is [].

This property can be used as the source for data binding. When this property is modified, it dispatches the propertyChange event.



Implementation
    public function get entries():Array
    public function set entries(value:Array):void

interpolationMethod

property 
interpolationMethod:String

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

A value from the InterpolationMethod class that specifies which interpolation method to use.

Valid values are InterpolationMethod.LINEAR_RGB and InterpolationMethod.RGB.

The default value is InterpolationMethod.RGB.



Implementation
    public function get interpolationMethod():String
    public function set interpolationMethod(value:String):void

matrix

property 
matrix:Matrix

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

An array of values used for matrix transformation.

The gradient scaleX and scaleY properties represent pixels while the Matrix scale properties represent multipliers. Thus they are not compatible. Another difference is the most of the transform properties (x, y, scaleX, and scaleY) support NaN values while the matrix does not. A NaN value means that the gradient will choose an appropriate value.

The scaleX and scaleY properties can not be represented by the matrix. Once the matrix is set, scaleX and scaleY can no longer be set. Also, x and y can not be set to NaN. The matrix can be set back to null which also resets all of the convenience transform properties back to their default values.

If the matrix is set, then the gradient draw logic will scale the gradient to fit the bounds of the graphic element. It will then position the gradient in the upper left corner of the graphic element. Finally, it will apply the matrix transformations.

By default, the LinearGradientStroke defines a transition from left to right across the control. Use the rotation property to control the transition direction. For example, a value of 180.0 causes the transition to occur from right to left, rather than from left to right.

The default value is null.



Implementation
    public function get matrix():Matrix
    public function set matrix(value:Matrix):void

rotation

property 
rotation:Number

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

By default, the LinearGradientStroke defines a transition from left to right across the control. Use the rotation property to control the transition direction. For example, a value of 180.0 causes the transition to occur from right to left, rather than from left to right.

The default value is 0.0.

This property can be used as the source for data binding. When this property is modified, it dispatches the propertyChange event.



Implementation
    public function get rotation():Number
    public function set rotation(value:Number):void

spreadMethod

property 
spreadMethod:String

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

A value from the SpreadMethod class that specifies which spread method to use.

Valid values are SpreadMethod.PAD, SpreadMethod.REFLECT, and SpreadMethod.REPEAT.

The default value is SpreadMethod.PAD.

This property can be used as the source for data binding. When this property is modified, it dispatches the propertyChange event.



Implementation
    public function get spreadMethod():String
    public function set spreadMethod(value:String):void

x

property 
x:Number

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

The distance by which to translate each point along the x axis.

This property can be used as the source for data binding. When this property is modified, it dispatches the propertyChange event.



Implementation
    public function get x():Number
    public function set x(value:Number):void

y

property 
y:Number

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

The distance by which to translate each point along the y axis.

This property can be used as the source for data binding. When this property is modified, it dispatches the propertyChange event.



Implementation
    public function get y():Number
    public function set y(value:Number):void
