IFocusManagerComponent  - AS3 Flex

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.

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.

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.

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.

If tabFocusEnabled, the order in which the component receives focus. If -1, then the component receives focus based on z-order.

Called by the FocusManager when the component receives focus. The component should draw or hide a graphic that indicates that the component has focus.

Called by the FocusManager when the component receives focus. The component may in turn set focus to an internal component.
