alpha | property |
alpha:Number| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
The alpha for this design layer instance, between 0.0 and 1.0.
When updated, the appropriate change event for effectiveAlpha
will be dispatched to all layerPropertyChange listeners
for this layer, as well as those of affected descendant layers if any.
The default value is 1.0.
Implementation

effectiveAlpha:Number [read-only] | Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Property that returns the effective alpha, between 0.0 and 1.0, of this design layer. This value multiplies the alpha of this layer by the alpha of any ancestor layers.
The default value is 1.0.
Implementation
public function get effectiveAlpha():NumbereffectiveVisibility | property |
effectiveVisibility:Boolean [read-only] | Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Returns the effective visibility of this design layer. This value takes into consideration the visibility of this layer and any ancestor layers.
The default value is true.
Implementation
public function get effectiveVisibility():Booleanid | property |
id:String| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
ID of the layer component. This value becomes the instance name of the layer and as such, should not contain any white space or special characters.

parent | property |
parent:DesignLayer [read-only] | Language Version: | ActionScript 3.0 |

| Runtime Versions: | Flash Player 10, AIR 1.5 |
This layer's parent layer.
The default value is null.
Implementation
public function get parent():DesignLayervisible | property |
visible:Boolean| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
The visibility for this design layer instance.
When updated, the appropriate change event for effectiveVisibility
will be dispatched to all layerPropertyChange listeners for
this layer, as well as those of affected descendant layers if any.
The default value is true.

Constructor.
addLayer | () | method |
public function addLayer(value:DesignLayer):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Adds a DesignLayer child to this layer.
Parameters
value:DesignLayer — The layer child to add.
|
getLayerAt | () | method |
public function getLayerAt(index:int):DesignLayer| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Returns the DesignLayer child at the specified index.
Note that the order of DesignLayer children is insignificant.
The getLayerAt method is meant to be used in
conjunction with numLayers to iterate over the child list.
Parameters
index:int — The 0-based index of a DesignLayer child.
|
DesignLayer — The specified DesignLayer child if index is between
0 and numLayers - 1. Returns null
if the index is invalid.
