IStyleClient

Package | mx.styles
Interface | public interface IStyleClient extends ISimpleStyleClient
Implementors | AdvancedDataGridItemRenderer, DataGridItemRenderer, DefaultGridItemRenderer, FTEAdvancedDataGridItemRenderer, FTEDataGridItemRenderer, HaloFocusRect, UITextFieldGridItemRenderer

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

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.

Property Detail

className | property

`className:String` [read-only]

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

The name of the component class.

Implementation
`public function get className():String`

inheritingStyles | property |

`inheritingStyles:Object`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

An object containing the inheritable styles for this component.

Implementation
`public function get inheritingStyles():Object`
`public function set inheritingStyles(value:Object):void`

nonInheritingStyles | property |

`nonInheritingStyles:Object`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

An object containing the noninheritable styles for this component.

Implementation
`public function get nonInheritingStyles():Object`
`public function set nonInheritingStyles(value:Object):void`

styleDeclaration | property |

`styleDeclaration:CSSStyleDeclaration`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

The style declaration that holds the inline styles declared by this object.

Implementation
`public function get styleDeclaration():CSSStyleDeclaration`
`public function set styleDeclaration(value:CSSStyleDeclaration):void`

Method Detail

clearStyle | () | method

`public function clearStyle(styleProp:String):void`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

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.

Parameters

| `styleProp:String` — Name of the style property.
| `newValue:*` — New value for the style.
