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.
Dispatched by the layer when either effectiveVisibility or effectiveAlpha changes.
DesignLayer
Property Detail
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 public function get alpha():Number public function set alpha(value:Number):void
effectiveAlpha
property
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():Number
effectiveVisibility
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():Boolean
id
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.
Implementation public function get id():String public function set id(value:String):void
numLayers
property
numLayers:int [read-only]
Language Version :
ActionScript 3.0
Product Version :
Flex 4
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
Implementation public function get parent():DesignLayer
visible
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.
Implementation public function get visible():Boolean public function set visible(value:Boolean):void
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.

initialized
()
method
public function initialized(document:Object, id:String):void
Language Version :
ActionScript 3.0
Product Version :
Flex 4
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.
