런타임 버전: | Flash Player 9, AIR 1.1 |
A flag that indicates whether the component can receive focus when selected.
As an optimization, if a child component in your component
implements the IFocusManagerComponent interface, and you
never want it to receive focus,
you can set focusEnabled
to false
before calling addChild()
on the child component.
This will cause the FocusManager to ignore this component
and not monitor it for changes to the tabFocusEnabled
,
hasFocusableChildren
, and mouseFocusEnabled
properties.
This also means you cannot change this value after
addChild()
and expect the FocusManager to notice.
Note: It does not mean that you cannot give this object focus
programmatically in your setFocus()
method;
it just tells the FocusManager to ignore this IFocusManagerComponent
component in the Tab and mouse searches.

hasFocusableChildren:Boolean
언어 버전: | ActionScript 3.0 |
제품 버전: | Flex 4 |
런타임 버전: | Flash Player 10, AIR 1.5 |
A flag that indicates whether child objects can receive focus.
Note: This property is similar to the tabChildren
property
used by Flash Player.
Use the hasFocusableChildren
property with Flex applications.
Do not use the tabChildren
property.
This property is usually false
because most components
either receive focus themselves or delegate focus to a single
internal sub-component and appear as if the component has
received focus.
For example, a TextInput control contains a focusable
child RichEditableText control, but while the RichEditableText
sub-component actually receives focus, it appears as if the
TextInput has focus. TextInput sets hasFocusableChildren
to false
because TextInput is considered the
component that has focus. Its internal structure is an
abstraction.
Usually only navigator components, such as TabNavigator and
Accordion, have this flag set to true
because they
receive focus on Tab but focus goes to components in the child
containers on further Tabs.
The default value is false
, except for the
spark.components.Scroller component.
For that component, the default value is true
.

[읽기 전용] 언어 버전: | ActionScript 3.0 |

런타임 버전: | Flash Player 9, AIR 1.1 |
A flag that indicates whether the component can receive focus
when selected with the mouse.
If false
, focus will be transferred to
the first parent that is mouseFocusEnabled
.

[읽기 전용] 언어 버전: | ActionScript 3.0 |
제품 버전: | Flex 4 |
런타임 버전: | Flash Player 10, AIR 1.5 |
A flag that indicates whether pressing the Tab key eventually
moves focus to this component.
Even if false
, you can still be given focus
by being selected with the mouse or via a call to
setFocus()
. This property replaces
InteractiveObject.tabEnabled which must be set to true
in Flex apps.
