| 產品版本: | Flex 4 |
| 執行階段版本: | 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.
預設值為 1.0。

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.
預設值為 true。
實作
public function get visible():Boolean public function set visible(value:Boolean):voidDesignLayer | () | 建構函式 |
public function DesignLayer()| 語言版本: | ActionScript 3.0 |

Adds a DesignLayer child to this layer.
參數
value:DesignLayer — The layer child to add.
|
getLayerAt | () | 方法 |
public function getLayerAt(index:int):DesignLayer| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 4 |
| 執行階段版本: | 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.
參數
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.

參數
document:Object — The MXML document that created this object.
| |
id:String — The identifier used by document to refer
to this object.
