Property Detail

actualHeight | property

`protected var actualHeight:Number = 0`

The final height value that should be used for layout. If the height has been explicitly set, then that value is used. If not, the actual height will be calculated automatically. Each component has different automatic sizing behavior, but it's usually based on the component's skin or content, including text or subcomponents.

actualWidth | property |

`protected var actualWidth:Number = 0`

The final width value that should be used for layout. If the width has been explicitly set, then that value is used. If not, the actual width will be calculated automatically. Each component has different automatic sizing behavior, but it's usually based on the component's skin or content, including text or subcomponents.

clipRect | property |

`clipRect:Rectangle`[override]

Implementation
`public function get clipRect():Rectangle`
`public function set clipRect(value:Rectangle):void`

defaultTextEditorFactory | property |

`public static var defaultTextEditorFactory:Function`

A function used by all UI controls that support text editor to create an `ITextEditor` instance. You may replace the default function with your own, if you prefer not to use the `StageTextTextEditor`.

The function is expected to have the following signature:

    function():ITextEditor

http://wiki.starling-framework.org/feathers/text-editors
feathers.core.ITextEditor

defaultTextRendererFactory | property |

`public static var defaultTextRendererFactory:Function`

A function used by all UI controls that support text renderers to create an ITextRenderer instance. You may replace the default function with your own, if you prefer not to use the BitmapFontTextRenderer.

The function is expected to have the following signature:

    function():ITextRenderer

See also

http://wiki.starling-framework.org/feathers/text-renderers
feathers.core.ITextRenderer

explicitHeight | property |

`protected var explicitHeight:Number = NaN`

The height value explicitly set by calling the height setter or setSize().

explicitWidth | property |

`protected var explicitWidth:Number = NaN`

The width value explicitly set by calling the width setter or setSize().

focusManager | property |

`focusManager:IFocusManager`

The current focus manager for this component.

Implementation
`public function get focusManager():IFocusManager`
`public function set focusManager(value:IFocusManager):void`

height | property |

`height:Number`[override]

The height of the component, in pixels. This could be a value that was set explicitly, or the component will automatically resize if no explicit height value is provided. Each component has a different automatic sizing behavior, but it's usually based on the component's skin or content, including text or subcomponents.

Note: Values of the `width` and `height` properties may not be accurate until after validation. If you are seeing `width` or `height` values of `0`, but you can see something on the screen and know that the value should be larger, it may be because you asked for the dimensions before the component had validated. Call `validate()` to tell the component to immediately redraw and calculate an accurate values for the dimensions.

Implementation
`public function get height():Number`
`public function set height(value:Number):void`

feathers.core.IFeathersControl.validate()

includeInLayout | property |

Implementation
`public function get isInitialized():Boolean`

isQuickHitAreaEnabled | property |

`isQuickHitAreaEnabled:Boolean`

Similar to mouseChildren on the classic display list. If true, children cannot dispatch touch events, but hit tests will be much faster.

Implementation
`public function get minTouchHeight():Number`
`public function set minTouchHeight(value:Number):void`

minTouchWidth | property |

`minTouchWidth:Number`

If using `isQuickHitAreaEnabled`, and the hit area's width is smaller than this value, it will be expanded.

Implementation

width | property |

`width:Number`[override]

The width of the component, in pixels. This could be a value that was set explicitly, or the component will automatically resize if no explicit width value is provided. Each component has a different automatic sizing behavior, but it's usually based on the component's skin or content, including text or subcomponents.

Note: Values of the `width` and `height` properties may not be accurate until after validation.

Constructor Detail

FeathersControl | () | Constructor

`public function FeathersControl()`

Constructor.

Method Detail

draw | () | method

`protected function draw():void`

Override to customize layout and to adjust properties of children. Called when the component validates, if any flags have been marked to indicate that validation is pending.

initialize | () | method |

`protected function initialize():void`

Called the first time that the UI control is added to the stage, and you should override this function to customize the initialization process. Do things like create children and set up event listeners. After this function is called, `FeathersEventType.INITIALIZE` is dispatched.

See also

feathers.events.FeathersEventType.INITIALIZE

invalidate | () | method |

`public function invalidate(flag:String):void`

Call this function to tell the UI control that a redraw is pending. The redraw will happen immediately before Starling renders the UI control to the screen. The validation system exists to ensure that multiple properties can be set together without redrawing multiple times in between each property change.

If you cannot wait until later for the validation to happen, you can call `validate()` to redraw immediately. As an example, you might want to validate immediately if you need to access the correct `width` or `height` values of the UI control, since these values are calculated during validation.

Parameters

| `flag:String` (default = `NaN`)``

See also

feathers.core.FeathersControl.validate()

isInvalid | () | method |

`public function isInvalid(flag:String = null):Boolean`

Indicates whether the control is pending validation or not. By default, returns `true` if any invalidation flag has been set. If you pass in a specific flag, returns `true` only if that flag has been set (others may be set too, but it checks the specific flag only. If all flags have been marked as invalid, always returns `true`.

Parameters

| `flag:String` (default = `null`)``

Returns

| `Boolean`

setSize | () | method |

`public function setSize(width:Number, height:Number):void`

Sets both the width and the height of the control.

Parameters

| `width:Number`
| `height:Number`

setSizeInternal | () | method |

`protected function setSizeInternal(width:Number, height:Number, canInvalidate:Boolean):Boolean`

Sets the width and height of the control, with the option of invalidating or not. Intended to be used when the `width` and `height` values have not been set explicitly, and the UI control needs to measure itself and choose an "ideal" size.

Parameters

| `width:Number`
| `height:Number`
| `canInvalidate:Boolean`

Returns

| `Boolean`

validate | () | method |

`public function validate():void`

Immediately validates the control, which triggers a redraw, if one is pending. Validation exists to postpone redrawing a component until the last possible moment before rendering so that multiple properties can be changed at once without requiring a full redraw after each change.

A component cannot validate if it does not have access to the stage and if it hasn't initialized yet. A component initializes the first time that it has been added to the stage.
