Property Detail
focusManagerproperty
focusManager:IFocusManager

The current focus manager for this component. May be null if no focus manager is enabled.


Implementation
    public function get focusManager():IFocusManager
    public function set focusManager(value:IFocusManager):void
focusOwnerproperty 
focusOwner:IFocusDisplayObject

    object.focusOwner = otherObject;


Implementation
    public function get focusOwner():IFocusDisplayObject
    public function set focusOwner(value:IFocusDisplayObject):void
isFocusEnabledproperty 
isFocusEnabled:Boolean

Determines if this component can receive focus.

In the following example, the focus is disabled:

    object.isFocusEnabled = false;


Implementation
    public function get isFocusEnabled():Boolean
    public function set isFocusEnabled(value:Boolean):void
isShowingFocusproperty 
isShowingFocus:Boolean  [read-only]

Indicates if the showFocus() method has been called on the object when it has focus.

Method Detail
hideFocus()method
public function hideFocus():void

If the visual indicator of focus has been displayed by showFocus(), call this function to hide it.

Important: This function will not clear focus from the display object if it has focus. To clear focus from the display object, you should set the focus property on the focus manager to null or another display object.

See also

showFocus()method 
public function showFocus():void

If the object has focus, an additional visual indicator may optionally be displayed to highlight the object. Calling this function may have no effect. It's merely a suggestion to the object.

Important: This function will not give focus to the display object if it doesn't have focus. To give focus to the display object, you should set the focus property on the focus manager.

    object.focusManager.focus = object;

Event Detail
focusIn Event
Event Object Type: starling.events.Event
Event.type property = feathers.events.FeathersEventType.FOCUS_IN

Dispatched when the display object receives focus.

The properties of the event object have the following values:

PropertyValue
bubblesfalse
currentTargetThe Object that defines the event listener that handles the event. For example, if you use myButton.addEventListener() to register an event listener, myButton is the value of the currentTarget.
datanull
targetThe Object that dispatched the event; it is not always the Object listening for the event. Use the currentTarget property to always access the Object listening for the event.

The FeathersEventType.FOCUS_IN event type is used by Feathers components to indicate when they have received focus.
focusOut Event  
Event Object Type: starling.events.Event
Event.type property = feathers.events.FeathersEventType.FOCUS_OUT

Dispatched when the display object loses focus.

The properties of the event object have the following values:

PropertyValue
bubblesfalse
currentTargetThe Object that defines the event listener that handles the event. For example, if you use myButton.addEventListener() to register an event listener, myButton is the value of the currentTarget.
datanull
targetThe Object that dispatched the event; it is not always the Object listening for the event. Use the currentTarget property to always access the Object listening for the event.

The FeathersEventType.FOCUS_OUT event type is used by Feathers components to indicate when they have lost focus.
