creationPolicy | 屬性 |
creationPolicy:String| 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 |
The creation policy for the items.
This property determines when the itemsFactory will create
the instance of the items.
Flex uses this property only if you specify an itemsFactory property.
The following values are valid:
| Value | Meaning |
|---|---|
auto | (default)Create the instance the first time it is needed. |
all | Create the instance when the application started up. |
none | Do not automatically create the instance.
You must call the createInstance() method to create
the instance. |
預設值為 "auto"。
實作
public function get creationPolicy():String public function set creationPolicy(value:String):voiddestination | 屬性 |
public var destination:Object| 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 |
The object relative to which the child is added. This property is used
in conjunction with the position property.
This property is optional; if
you omit it, Flex uses the immediate parent of the State
object, that is, the component that has the states
property, or <mx:states>tag that specifies the State
object.
destructionPolicy | 屬性 |
destructionPolicy:String| 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 |
The destruction policy for the items.
This property determines when the itemsFactory will destroy
the deferred instances it manages. By default once instantiated, all
instances are cached (destruction policy of 'never').
Flex uses this property only if you specify an itemsFactory property.
The following values are valid:
| Value | Meaning |
|---|---|
never | (default)Once created never destroy the instance. |
auto | Destroy the instance when the override no longer applies. |
預設值為 "never"。
實作
public function get destructionPolicy():String public function set destructionPolicy(value:String):voidisArray | 屬性 |
public var isArray:Boolean = false| 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 |
Denotes whether or not the collection represented by the target property is to be treated as a single array instance instead of a collection of items (the default).
預設值為 false。
isStyle | 屬性 |
public var isStyle:Boolean = false| 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 |
Denotes whether or not the collection represented by the target property is a style.
預設值為 false。
items | 屬性 |
items:*| 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 |
The items to be added.
If you set this property, the items are created at app startup.
Setting this property is equivalent to setting a itemsFactory
property with a creationPolicy of "all".
Do not set this property if you set the itemsFactory
property.
實作
public function get items():* public function set items(value:any):voiditemsFactory | 屬性 |
itemsFactory:mx.core:ITransientDeferredInstance| 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 |
The factory that creates the items.
If you set this property, the items are instantiated at the time
determined by the creationPolicy property.
Do not set this property if you set the items
property.
This propety is the AddItems class default property.
Setting this property with a creationPolicy of "all"
is equivalent to setting a items property.
實作
public function get itemsFactory():mx.core:ITransientDeferredInstance public function set itemsFactory(value:mx.core:ITransientDeferredInstance):voidposition | 屬性 |
public var position:String = "last"| 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 |
The position of the child in the display list, relative to the
object specified by the relativeTo property.
預設值為 AddItems.LAST。
propertyName | 屬性 |
public var propertyName:String| 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 |
The name of the Array property that is being modified. If the destination
property is a Group or Container, this property is optional. If not defined, the
items will be added as children of the Group/Container.
relativeTo | 屬性 |
public var relativeTo:Object| 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 |
The object relative to which the child is added. This property is only
used when the position property is AddItems.BEFORE
or AddItems.AFTER.
vectorClass | 屬性 |
public var vectorClass:Class| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 4.5 |
| 執行階段版本: | Flash Player 10, AIR 1.5 |
When the collection represented by the target property is a Vector, vectorClass is the type of the target. It is used to initialize the target property.
AddItems | () | 建構函式 |
public function AddItems()| 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 |
Constructor.
apply | () | 方法 |
override public function apply(parent:UIComponent):void| 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 |
Applies the override. Flex retains the original value, so that it can
restore the value later in the remove() method.
This method is called automatically when the state is entered. It should not be called directly.
參數
parent:UIComponent — The parent of the state object containing this override.
The override should use this as its target if an explicit target was
not specified.
|
createInstance | () | 方法 |
public function createInstance():void| 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 |
Creates the items instance from the factory.
You must use this method only if you specify a targetItems
property and a creationPolicy value of "none".
Flex automatically calls this method if the creationPolicy
property value is "auto" or "all".
If you call this method multiple times, the items instance is
created only on the first call.
initialize | () | 方法 |
override public function initialize():void| 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 |
IOverride interface method; this class implements it as an empty method.
remove | () | 方法 |
override public function remove(parent:UIComponent):void| 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 |
Removes the override. The value remembered in the apply()
method is restored.
This method is called automatically when the state is entered. It should not be called directly.
參數
parent:UIComponent — The parent of the state object containing this override.
The override should use this as its target if an explicit target was
not specified.
