Detalhes da propriedade
defaultButtonpropriedade
defaultButton:IUIComponent  [read-write]

A reference to the original default Button control. Pressing the Enter key while the focus is on any control activates the Button control by dispatching a click event on the Button control, just as if it was clicked with the mouse. The actual default Button control changes if focus is given to another Button control, but switches back to the original if focus is not on a button.

This property is managed by Flex containers; do not set it directly to specify the default button.

The defaultButton must be of class mx.controls.Button even though this property is of type IUIComponent.

defaultButtonEnabledpropriedade 
defaultButtonEnabled:Boolean  [read-write]

A flag that indicates whether the FocusManager should check for the Enter key being pressed to activate the default button. TextArea and other components that want to recognize the Enter key set this property to false to disable the Enter key from dispatching a click event on the default button, if it exists.

focusPanepropriedade 
focusPane:Sprite  [read-write]

A single Sprite that is moved from container to container as the focus moves to those containers. The Sprite is used as the parent of the visual indicator that a component has focus.

nextTabIndexpropriedade 
nextTabIndex:int  [read-only]

    public function get nextTabIndex():int
showFocusIndicatorpropriedade 
showFocusIndicator:Boolean  [read-write]

A flag that indicates whether to display an indicator that a component has focus. If true a component receiving focus draws a visible indicator that it has focus.

By default, this is false until the user uses the Tab key, then it is set to true.

In general it is better to use the showFocus() and hideFocus() methods to change this property as those methods also update the visual indicator that a component has focus.

Detalhes do método
activate()método
public function activate():void

The SystemManager activates and deactivates a FocusManager if more than one IFocusManagerContainer is visible at the same time. If the mouse is clicked in an IFocusManagerContainer with a deactivated FocusManager, the SystemManager will call the activate() method on that FocusManager. The FocusManager that was activated will have its deactivate() method called prior to the activation of another FocusManager.

deactivate()método 
public function deactivate():void

The SystemManager activates and deactivates a FocusManager if more than one IFocusManagerContainer is visible at the same time. If the mouse is clicked in an IFocusManagerContainer with a deactivated FocusManager, the SystemManager will call the activate() method on that FocusManager. The FocusManager that was activated will have its deactivate() method called prior to the activation of another FocusManager.

findFocusManagerComponent()método 
public function findFocusManagerComponent(o:InteractiveObject):IFocusManagerComponent

Returns the IFocusManagerComponent that contains the given object, if any. Because the player can set focus to a subcomponent of a Flex component this method determines which IFocusManagerComponent has focus from the component perspective.

Parâmetros

o:InteractiveObject — An object that can have player-level focus.

Retorna
IFocusManagerComponent — The IFOcusManagerComponent containing o or null
getFocus()método 
public function getFocus():IFocusManagerComponent

Gets the IFocusManagerComponent component that currently has the focus. Calling this method is recommended instead of using the Stage object because it indicates which component has focus. The Stage might return a subcomponent in that component.

Retorna
IFocusManagerComponent — IFocusManagerComponent object that has focus.
getNextFocusManagerComponent()método 
public function getNextFocusManagerComponent(backward:Boolean = false):IFocusManagerComponent

Returns the IFocusManagerComponent that would receive focus if the user pressed the Tab key to navigate to another component. It will return the same component as the current focused component if there are no other valid components in the application.

Parâmetros

backward:Boolean (default = false) — If true, return the object as if the Shift-Tab keys were pressed.

Retorna
IFocusManagerComponent — The component that would receive focus.
hideFocus()método 
public function hideFocus():void

Sets showFocusIndicator to false and removes the visual focus indicator from the focused object, if any.

setFocus()método 
public function setFocus(o:IFocusManagerComponent):void

Sets focus to an IFocusManagerComponent component. Does not check for the components visibility, enabled state, or any other conditions.

Parâmetros

o:IFocusManagerComponent — A component that can receive focus.

showFocus()método 
public function showFocus():void

Sets showFocusIndicator to true and draws the visual focus indicator on the focused object, if any.
