The DesignLayer class represents a visibility group that can be associated
with one or more IVisualElement instances at runtime.
DesignLayer instances support a
visible
and alpha property
that when set will propagate to the associated layer children.
alpha:Number
Language Version: | ActionScript 3.0 |
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 public function get alpha():Number
public function set alpha(value:Number):void
effectiveAlpha:Number
[read-only]
Language Version: | ActionScript 3.0 |
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():Number
effectiveVisibility:Boolean
[read-only]
Language Version: | ActionScript 3.0 |
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():Boolean
id:String
Language Version: | ActionScript 3.0 |
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.
Implementation public function get id():String
public function set id(value:String):void
numLayers:int
[read-only]
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
The number of DesignLayer children directly parented by this layer.
The default value is 0.
Implementation public function get numLayers():int
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():DesignLayer
visible:Boolean
Language Version: | ActionScript 3.0 |
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.
Implementation public function get visible():Boolean
public function set visible(value:Boolean):void
public function DesignLayer()
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Constructor.
public function addLayer(value:DesignLayer):void
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Adds a DesignLayer child to this layer.
Parameters
public function getLayerAt(index:int):DesignLayer
Language Version: | ActionScript 3.0 |
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.
|
Returns | DesignLayer — The specified DesignLayer child if index is between
0 and numLayers - 1. Returns null
if the index is invalid.

public function initialized(document:Object, id:String):void
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Called after the implementing object has been created and all
component properties specified on the MXML tag have been initialized.
Parameters
| document:Object — The MXML document that created this object.
|
|
| id:String — The identifier used by document to refer
to this object.
If the object is a deep property on document ,
id is null.

public function removeLayer(value:DesignLayer):void
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Removes a DesignLayer child from this layer.
Parameters
Event Object Type: mx.events.PropertyChangeEvent
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Dispatched by the layer when either effectiveVisibility
or
effectiveAlpha
changes.
