This interface describes the properties and methods that an object
must implement so that it can fully participate in the style subsystem.
This interface is implemented by UIComponent.
If the object does not need to store style values locally, it can
implement the ISimpleStyleClient interface instead.
Deletes a style property from this component instance.
This does not necessarily cause the getStyle() method to return
undefined.
Parameters
styleProp:String — Name of the style property.
getClassStyleDeclarations
()
method
public function getClassStyleDeclarations():Array
Language Version :
ActionScript 3.0
Product Version :
Flex 3
Runtime Versions :
Flash Player 9, AIR 1.1
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.
Returns
Array — Array of CSSStyleDeclaration objects.
getStyle
()
method
public function getStyle(styleProp:String):*
Language Version :
ActionScript 3.0
Product Version :
Flex 3
Runtime Versions :
Flash Player 9, AIR 1.1
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.
Parameters
styleProp:String — Name of the style property.
Returns
* — Style value.
notifyStyleChangeInChildren
()
method
public function notifyStyleChangeInChildren(styleProp:String, recursive:Boolean):void
Language Version :
ActionScript 3.0
Product Version :
Flex 3
Runtime Versions :
Flash Player 9, AIR 1.1
Propagates style changes to the children of this component.
Parameters
styleProp:String — Name of the style property.
recursive:Boolean — Whether to propagate the style changes to the children's children.
regenerateStyleCache
()
method
public function regenerateStyleCache(recursive:Boolean):void
Language Version :
ActionScript 3.0
Product Version :
Flex 3
Runtime Versions :
Flash Player 9, AIR 1.1
Sets up the internal style cache values so that the getStyle()
method functions.
If this object already has children, then reinitialize the children's
style caches.
Parameters
recursive:Boolean — Regenerate the proto chains of the children.
registerEffects
()
method
public function registerEffects(effects:Array):void
Language Version :
ActionScript 3.0
Product Version :
Flex 3
Runtime Versions :
Flash Player 9, AIR 1.1
Registers the EffectManager as one of the event listeners for each effect event.
Parameters
effects:Array — An Array of Strings of effect names.
setStyle
()
method
public function setStyle(styleProp:String, newValue:*):void
Language Version :
ActionScript 3.0
Product Version :
Flex 3
Runtime Versions :
Flash Player 9, AIR 1.1
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.
