A base class that can be used when implementing an object that uses the IAdvancedStyleClient interface. The base class supplies implementations of the methods and properties required for an object to participate in the style subsystem.

In addition to the IAdvancedStyleClient interface, this object also implements the IFlexModule and IMXMLObject interfaces. The IMXMLObject interface contains an initialized method that is called when the class is instantiated using an MXML declaration. The implementation of the initialized method provided by this base class will add the class instance to the document object that contains the MXML declaration. For more details, see the description of the initilized method.

Constructor.

Detalhes do método

clearStyle

()

método

public function clearStyle(styleProp:String):void

Versão da linguagem:

ActionScript 3.0

Versão de produto:

Flex 4.5

Versões de runtime:

Flash Player 10, AIR 2.5

Deletes a style property from this component instance.

This does not necessarily cause the getStyle() method to return undefined.

Parâmetros

styleProp:String — Name of the style property.

getClassStyleDeclarations

()

método

public function getClassStyleDeclarations():Array

Versão da linguagem:

ActionScript 3.0

Versão de produto:

Flex 4.5

Versões de runtime:

Flash Player 10, AIR 2.5

Returns an Array of CSSStyleDeclaration objects for the type selector that applies to this component, or null if none exist.

For example, suppose that component MyButton extends Button. This method first looks for a MyButton selector; then, it looks for a Button type selector; finally, it looks for a UIComponent type selector.

Retorna

Array — Array of CSSStyleDeclaration objects.

getStyle

()

método

public function getStyle(styleProp:String):*

Versão da linguagem:

ActionScript 3.0

Versão de produto:

Flex 4.5

Versões de runtime:

Flash Player 10, AIR 2.5

Gets a style property that has been set anywhere in this component's style lookup chain.

This same method is used to get any kind of style property, so the value returned may be a Boolean, String, Number, int, uint (for an RGB color), Class (for a skin), or any kind of object. Therefore the return type is specified as *.

If you are getting a particular style property, you will know its type and will often want to store the result in a variable of that type. You can use either the as operator or coercion to do this. For example:

      var backgroundColor:uint = getStyle("backgroundColor") as int;
      
      or
      
      var backgroundColor:uint = int(getStyle("backgroundColor"));

If the style property has not been set anywhere in the style lookup chain, the value returned by the getStyle() method is undefined. Note that undefined is a special value that is not the same as false, the empty String (""), NaN, 0, or null. No valid style value is ever undefined. You can use the static method StyleManager.isValidStyleValue() to test whether the value was set.

Parâmetros

styleProp:String — Name of the style property.

Retorna

* — Style value.

hasCSSState

()

método

public function hasCSSState():Boolean

Versão da linguagem:

ActionScript 3.0

Versão de produto:

Flex 4.6

Versões de runtime:

Flash Player 10, AIR 2.5

Returns true if currentCSSState is not null. Typically, you do not call this method directly. It is called by the mx.styles.CSSCondition.matchesStyleClient() method.

Note Spark components use their skin state as the pseudo state. Halo components use the currentState property.

Retorna

Boolean — true if currentCSSState is not null. By default, currentCSSState is the same as currentState. If no state exists, return false.

initialized

()

método

public function initialized(document:Object, id:String):void

Versão da linguagem:

ActionScript 3.0

Versão de produto:

Flex 4.5

Versões de runtime:

Flash Player 10, AIR 2.5

The initialized method is called when this class or a class that extends this class is used in an MXML declaration. It is called after the implementing object has been created and all component properties specified on the MXML tag have been initialized.

If the document that created this object is a UIComponent, (e.g. Application, Module, etc.) then the UIComponent's addStyleClient method will be called to add this object to the UIComponent's list of non-visual style clients. This allows the object to inherit styles from the document.

Parâmetros

	`document:Object` — The MXML document that created this object.

	`id:String` — The identifier used by the document object to refer to this object.

matchesCSSState

()

método

public function matchesCSSState(cssState:String):Boolean

Versão da linguagem:

ActionScript 3.0

Versão de produto:

Flex 4.5

Versões de runtime:

Flash Player 10, AIR 2.5

Returns true if cssState matches currentCSSState. Typically, you do not call this method directly. It is called by the mx.styles.CSSCondition.matchesStyleClient() method.

Note Spark components use their skin state as the pseudo state. Halo components use the currentState property.

Parâmetros

cssState:String — A possible value of CSSCondition.value. It represents the current state of this component used to match CSS pseudo-selectors.

Retorna

Boolean — true if cssState matches currentCSSState. By default, currentCSSState is the same as currentState. If no state exists, return null.

matchesCSSType

()

método

public function matchesCSSType(cssType:String):Boolean

Versão da linguagem:

ActionScript 3.0

Versão de produto:

Flex 4.5

Versões de runtime:

Flash Player 10, AIR 2.5

Determines whether this instance is the same as, or is a subclass of, the given type. Typically, you do not call this method directly. It is called by the mx.styles.CSSCondition.matchesStyleClient() method.

Parâmetros

cssType:String — A CSSSelector object.

Retorna

Boolean — true if cssType is in the hierarchy of qualified type selectors.

notifyStyleChangeInChildren

()

método

public function notifyStyleChangeInChildren(styleProp:String, recursive:Boolean):void

Versão da linguagem:

ActionScript 3.0

Versão de produto:

Flex 4.5

Versões de runtime:

Flash Player 10, AIR 2.5

Propagates style changes to the children of this style client instance. A non-visual style client (i.e. a style client that is not a DisplayObject) does not have children, therefore this method does not do anything for non-visual style clients.

Parâmetros

	`styleProp:String` — Name of the style property.

	`recursive:Boolean` — Whether to propagate the style changes to the children's children.

regenerateStyleCache

()

método

public function regenerateStyleCache(recursive:Boolean):void

Versão da linguagem:

ActionScript 3.0

Versão de produto:

Flex 4.5

Versões de runtime:

Flash Player 10, AIR 2.5

Sets up the internal style cache values so that the getStyle() method functions.

Parâmetros

recursive:Boolean — Regenerate the proto chains of the children.

registerEffects

()

método

public function registerEffects(effects:Array):void

Versão da linguagem:

ActionScript 3.0

Versão de produto:

Flex 4.5

Versões de runtime:

Flash Player 10, AIR 2.5

Registers the EffectManager as one of the event listeners for each effect event.

Parâmetros

effects:Array — An Array of Strings of effect names.

setStyle

()

método

public function setStyle(styleProp:String, newValue:*):void

Versão da linguagem:

ActionScript 3.0

Versão de produto:

Flex 4.5

Versões de runtime:

Flash Player 10, AIR 2.5

Sets a style property on this component instance.

This may override a style that was set globally.

Calling the setStyle() method can result in decreased performance. Use it only when necessary.

Parâmetros

	`styleProp:String` — Name of the style property.

	`newValue:*` — New value for the style.

styleChanged

()

método

public function styleChanged(styleProp:String):void

Versão da linguagem:

ActionScript 3.0

Versão de produto:

Flex 4.5

Versões de runtime:

Flash Player 10, AIR 2.5

Detects changes to style properties. When any style property is set, Flex calls the styleChanged() method, passing to it the name of the style being set.

This is an advanced method that you might override when creating a subclass of AdvancedStyleClient. When you create a custom class, you can override the styleChanged() method to check the style name passed to it, and handle the change accordingly. This lets you override the default behavior of an existing style, or add your own custom style properties.

Parâmetros

styleProp:String — The name of the style property, or null if all styles for this style client have changed.

stylesInitialized

()

método

public function stylesInitialized():void

Versão da linguagem:

ActionScript 3.0

Versão de produto:

Flex 4.5

Versões de runtime:

Flash Player 10, AIR 2.5

Flex calls the stylesInitialized() method when the styles for a component are first initialized.
