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.

Descrizione dei metodi

clearStyle

()

metodo

public function clearStyle(styleProp:String):void

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4.5

Versioni 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.

Parametri

styleProp:String — Name of the style property.

getClassStyleDeclarations

()

metodo

public function getClassStyleDeclarations():Array

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4.5

Versioni 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.

Restituisce

Array — Array of CSSStyleDeclaration objects.

getStyle

()

metodo

public function getStyle(styleProp:String):*

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4.5

Versioni 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.

Parametri

styleProp:String — Name of the style property.

Restituisce

* — Style value.

hasCSSState

()

metodo

public function hasCSSState():Boolean

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4.6

Versioni 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.

Restituisce

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

initialized

()

metodo

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

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4.5

Versioni 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.

Parametri

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

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

matchesCSSState

()

metodo

public function matchesCSSState(cssState:String):Boolean

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4.5

Versioni 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.

Parametri

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

Restituisce

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

matchesCSSType

()

metodo

public function matchesCSSType(cssType:String):Boolean

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4.5

Versioni 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.

Parametri

cssType:String — A CSSSelector object.

Restituisce

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

notifyStyleChangeInChildren

()

metodo

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

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4.5

Versioni 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.

Parametri

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

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

regenerateStyleCache

()

metodo

public function regenerateStyleCache(recursive:Boolean):void

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4.5

Versioni runtime:

Flash Player 10, AIR 2.5

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

Parametri

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

registerEffects

()

metodo

public function registerEffects(effects:Array):void

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4.5

Versioni runtime:

Flash Player 10, AIR 2.5

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

Parametri

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

setStyle

()

metodo

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

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4.5

Versioni 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.

Parametri

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

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

styleChanged

()

metodo

public function styleChanged(styleProp:String):void

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4.5

Versioni 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.

Parametri

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

stylesInitialized

()

metodo

public function stylesInitialized():void

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 4.5

Versioni runtime:

Flash Player 10, AIR 2.5

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